Sucks to use Cocoapods, when the requirements are Realm.
Build time increases by 30 minutes for bigger projects.

Please add carthage support.

I'm not sure if this is just an error with my code but I have a Realmable that looks like this:

struct AnyEntity: Realmable {
    
    var id: String = ""
    var state: String = ""
    
    var attributes: EntityAttributes? = nil
    
    static func primaryKey() -> String? {
        return "id"
    }
}

The attributes is a class that looks like this:

class EntityAttributes: Realmable {
    required init() {
    }
}

and multiple other custom classes can inherit from EntityAttributes like this:

class LightAttributes: EntityAttributes {
    var brightness: Int? = nil
    var rgbColor: [Int]? = nil
}

Now when I save say for example a LightEntity, as the attributes variable of the AnyEntity Realmable this works fine.

let realm = try! Realm()
                    
let attributes = LightAttributes()
attributes.brightness = 1
attributes.rgbColor = [0, 255, 255]
                    
let newEntity = AnyEntity(entityId: "entity_0", state: "abc", attributes: attributes)
                    
try! realm.write {
    realm.add(newEntity, update: .modified)
}

But when I try to access the saved and cast the attributes variable from EntityAttributes to LightAttributes, it fails.

let realm = try! Realm()

let entity = realm.object(ofType: AnyEntity.self, forPrimaryKey: "entity_0")

// Fails with "Could not cast value of type 'EntityAttributes' (0x1041bf2f0) to 'LightAttributes' (0x1041bf380)."
let attributes = entity!.attributes as! LightEntity

Would it be possible to add MacOS support to Unrealm. Which area of the code is currently preventing Unrealm to run on Mac and needs to be adopt?

Thanks,

error: Unexpectedly found nil while unwrapping an Optional value

Hi,

I'm using unrealm to support structs as realm objects. However this comes with a performance hit.

I observed few things. LEts say there are 10k records in realm.

Reading the results from realm is pretty quick, its less than a second for those 10k items.

And when I try to convert them into an array, it becomes too slow. It is only converting 100 items per second into an array, so for 10k items, it is taking 100secs.

Do you recommend any solution to improve the loading speed ?

NOTE: I want to convert the realm results into an array because , I cant use predicates on structs. If I use class, I loose the swift features on struct.

Sample code:

        extension Task {
              static func all() -> Results<Task>? {
                    if let realm = try? Realm() {
                          return realm.objects(Task.self)
                    }
                     return .none
              }
        }
        if let tasks = Task.all() {
            DataManager.shared.tasks = Array(tasks)
        }

Hi !

I have a problem deserializing Data attribute of my model, when it's type is an optional Dictionary.

Here's an exemple of my model:

`
var id: String = UUID().uuidString
var name: String = ""
var bodyPart: String = ""

var type: String = "normal"
var globalRestTimer: Double = 0.0
var exerciseSpecificRestTimer: [Int: Double] = [0: 0.0]

var exercises: [Exercise]?
var exercisesTargetSets: [Int: Int]?
var exercisesTargetReps: [Int: Int]?

var createdAt: Date = Date()

static func primaryKey() -> String? {
return "id"
}`

I successfully saved data to the Realm, but always get a nil value when reading the data.

I think the problem is in the else if condition, where child.value is [AnyHashable:Any], let data = value as? Data always returns false when using optionals. Unrealm.swift -> readValues(from:)

Therefore, when setting property.set in the else statement, the value (Data) gets nullified.

} else { if let t = property.type as? RealmableEnum.Type, let val = t.init(rlmValue: value) { try property.set(value: val, on: &self) } else if child.value is [AnyHashable:Any], let data = value as? Data { if let json = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data) { try property.set(value: json, on: &self) } } else { try property.set(value: value, on: &self) } }

I've tried different workaround, but I can't make it work.

Does anybody have a solution?

Thanks !

i can not use with list of object, Ex: List, or arr : [Object],
how to use it ?

Thank you for your awesome Lib ! really nice to use.

I have a question: is there a way to change the realmClassPrefix set at "RLM" in RealmableBase ?

I'm using a full-sync read-only Realm and cannot change the classe name: "myClasse". So I would Like to set the realmClassPrefix to ""

I've tried:

extension MyClasse: Realmable {
    static func className() -> String { "myClasse" }
}

But It doesn't seam to affect the classe name.

I've also tried:

extension MyClasse: Realmable {
   static var realmClassPrefix: String { "My" }
}

But it seam to crash my app :/

Question: Does Unrealm support Realm objects with optional properties?
e.g.
struct Jukugo: Realmable {
public let id: Int? = 0
public let nameString: String? = ""
public let address: String? = ""
public let pinCode: Int? = 0

static func primaryKey() -> String?
{
return "id"
}
}

Hello,

I try to install Unrealm in Xcode11 Beta 5. When I try to instanciate Realm() it throws me an error : Terminating app due to uncaught exception 'RLMException', reason: 'Primary key property 'name' does not exist on object 'RealmSwiftClassPermission''

I saw that is because Realm and RealmSwift has to be explicitly add to Podfile to target Xcode11.

Podfile :

pod 'Unrealm'
pod 'Realm', git: 'https://github.com/realm/realm-cocoa.git', branch: 'tg/xcode-11-b1', submodules: true

pod 'RealmSwift', git: 'https://github.com/realm/realm-cocoa.git', branch: 'tg/xcode-11-b1', submodules: true

But now I got the following error : Unrealm was resolved to 0.1.0, which depends on
RealmSwift (= 3.15.0) was resolved to 3.15.0, which depends on
Realm (= 3.15.0)

I think it's because Unrealm pod doesn't support Xcode11. Is that correct ?

Hello,

I'm trying to make a Realm Compaction (will be triggered once in a while in RELEASE app), but somehow, using Unrealm prevents such a thing.

I'm trying to make the compaction has soon as the app has launched, but a thread has already opened a Realm instance.

If I try to make the compaction without registering Realmable, it doesn't work (as expected), but if I register them correctly, they open a Realm instance on the DB and can't compact it anymore.

What's the best way to handle this case ?

Thank you !

Hi,

As this moment, latest is 3.17.3.

Thanks

Hey @arturdev

I found this library and it's awesome! But I found a small issue (I think 😅).

I am having this enum and I registerd it inside AppDelegate

enum AgeRange: String, Codable, RealmableEnumString {
    case KID = "13-15"
    case TEENAGER = "16-18"
    case YOUNG_ADULT = "19-25"
    case LATE_TWENTIES = "26-30"
    case THIRTIES = "31-40"
    case MIDDLE_AGED = "41-60"
    case SENIOR = "60+"
}

And this class which is using the enum. (also registered)

final class PatientModel: Codable, Realmable {
    var uuid: String = ""
    var firstName: String?
    var lastName: String?
    var ageRange: AgeRange?
}

And I am getting this error at the build time

*** Terminating app due to uncaught exception 'RLMException', reason: 'Property 'ageRange' is declared as 'AgeRange', which is not a supported RLMObject property type. All properties must be primitives, NSString, NSDate, NSData, NSNumber, RLMArray, RLMLinkingObjects, or subclasses of RLMObject. See https://realm.io/docs/objc/latest/api/Classes/RLMObject.html for more information.'

It's a little bit strange because if I declare it as var ageRange: AgeRange (without optional) or var ageRange: [AgeRange]? = nil everything it's working.

I found a workaround by encoding and decoding manually, but it's a lot of work because I have many other fields inside PatientModel and it's a little bit annoying to write them again and again.

if let range = try container.decodeIfPresent(AgeRange.self, forKey: .ageRange) {
    self.ageRange = range
} else {
    self.ageRange = .KID
}

Am I missing something?

Thanks 😁

Hi,

I'm trying to save a simple model to the Realm, but somehow, the new version using NsKeyedArchiver is throwing an exception.

Error Domain=NSCocoaErrorDomain Code=4866 "The data couldn’t be written because it isn’t in the correct format." UserInfo={NSUnderlyingError=0x60000168e8e0 {Error Domain=NSCocoaErrorDomain Code=4864 "This decoder will only decode classes that adopt NSSecureCoding. Class '__SwiftValue' does not adopt it." UserInfo={NSDebugDescription=This decoder will only decode classes that adopt NSSecureCoding. Class '__SwiftValue' does not adopt it.}}}

Here's and exemple of the model I'm trying to save.

`struct Model: Realmable, Codable {

var id: String = UUID().uuidString
var name: String = ""
var cat: String = "default"

var type: String = "user"

var dictionary: [Int: [SomeArray]] = [:]

var startDate: Date?
var endDate: Date?

static func primaryKey() -> String? {
    return "id"
}

}`

It will save the model, but the dictionary variable will be nil.

I'm stuck there, I have tried many different solution but I won't work.

Thanks !

The SPM branch seems behind the master one and only supports Realm 4.X instead of Realm 5.X. Is it normal ?

Can see Realm version too old, please update to newer

Is there a way to use LinkingObjects?

LinkingObjects expects an Object type.

Happy to help implement this, I imagine it would require wrapping LinkingObjects to be compatible with Realmable instead of Object.

Possible to add support not just for 0.2.5? Thanks! This is what I get now if I try to build SPM unrealm on Catalyst:

Please update to suppourt Realm 10.5.1

Is there any migration mechanism similar to Realm's one (or any at all) ? If so, how do I use it?

Hi just found this and it's so nice to have the ability to use swift types instead of realm types! Keep up the good job!

I have a question about some types of properties that i'm not sure if they are supported or not but i saw one of them in your User object example so i thought maybe they would be. When I init the struct and print it out, I can see all those values. After i save them into realm and retrieve them the optional dictionary and array of enum shows up nil but the array of enum and dictionary that was inited to an empty value displays the correct value.

Optional Array of Enum
Optional Dictionary of String: String
Optional Enum = Crashes on build

Are those types above supported an i'm doing something wrong or are they not supported?

This is the testing struct I'm testing with:

The Init:

Was testing simple struct:

struct Foo: Realmable {
    
    let id: Int
    let name: String
    let readOnly: Bool
    let enabled: Bool
    
    static func primaryKey() -> String? {
        return "id"
    }
    
    init(id: Int, name: String, readOnly: Bool, enabled: Bool) {
        self.id = id
        self.name = name
        self.readOnly = readOnly
        self.enabled = enabled
    }
    
    init() {
        self.init(id: -1, name: "", readOnly: true, enabled: false)
    }
}

like this:

guard let realm = try? Realm() else { return }
let foo = Foo(id: 0, name: "test name", readOnly: false, enabled: true)
try? realm.write {
    realm.add(foo)
}
let foos = realm.objects(Foo.self).map({ $0 })

Found out problem with extracting properties with 0 or false value. Problem appears at this func:

guard let value = obj.value(forKey: propertyName) fails for such properties and they left default:

Need to add linter to a project for making easier the support from other people. Also, the source code has inconsistent indents, for example: 1st, 2nd

there are a few other places with issues through application code.

Hi! Any plans for including Realm 10.x support?

Hello,
the tool looks good, we were doing the transition manually (from Realms Object subclasses to Swifts structs).

But I see you are using reflection in your implementation which can cause some performance issues. I did not notice any cache for the reflection so my guess would be it might perform poorly for larger requests.

I was thinking of doing some sort of similar thing, but using Codable.

Currently Unrealm is on 3.18.0. There is 4.3.0 and even 5.0.0 beta.

https://github.com/realm/realm-cocoa/releases

Hello. I'm curious why was this code below added? I reinstalled my app and it worked but just curious why I have this in my database now. It's just an empty array so not sure what it's for.

addPropertyToClassIfNeeded(className: className, name: "__nilProperties", typeStr: "Array<String>")

Tried Installing by adding this line:
.package(url: "https://github.com/arturdev/Unrealm", from: "1.0.1")

or this (since the line above does not use the latest version that includes Realm 4.3.0)

.package(url: "https://github.com/arturdev/Unrealm", .branch("master"))

Hello,

First, thanks for the awesome library, very benefitting in use!

Xcode 11 has been crashing with:
Primary key property 'name' does not exist on object 'RealmSwiftPermissionRole'

It's a known issue that Realm fixed in their latest version 3.18.0. If you could update this library accordingly, that'd be great as I can't run my project until then.

Best,
-Sami

I am getting error while storing data using List() and [Object] in realm.

Struct object getting below error:

While storing array [Object] getting below error:

Is there any other way to store bulk data at a time using Unrealm?

Thanks!

For now, I keep Realm under 5.0 to use Unrealm.

Hey there,

I am trying to have a simple struct to be Realmable...

struct Sprite: Realmable {
    let id: String
    let position: CGPoint
    let size: CGSize
    let alpha: CGFloat
  
    static fun primaryKey() -> String { "id" }
}

I am adding extension RealmableEnum on each of these, matching Float, tried with NSNumber(cgPoint: ) and with NSCoder.string(cgPoint:).. is there a way to do so ?

Or should I basically just save JSON strings for each object, generated by Codable ?.. sounds less efficient to me

Hey @arturdev

This seems like an amazing library. However, one useful paradigm we use (with RxRealm) is the ability to observe changes on an object in the realm db and register a callback.

This function is the public func observe<T>(on queue: DispatchQueue? = nil, _ block: @escaping (RealmSwift.ObjectChange<T>) -> Void) -> RealmSwift.NotificationToken where T : RealmSwift.Object.

Does the fact that the objects are no longer "live" make this no longer possible?

I have this field in a struct Contact.

var customFields: [String: String?]?

I'm able to store this field in realm. It is storing as data field.

But when I try to fetch the contact and read it, the custom fields are empty.

Do I have to manually convert data. back into swift dicionary ?

At which level, do I have to do this conversion ?

Info:

At the line:

  let results = self.objects(cls)

when I do, po results.first, I can see the customField with some data in it.

customFields = <length = 24, bytes = 0x62706c6973743030d4010203040506070a58247665727369 — 1537 total bytes>;

Now after Results(rlmResult: results) happens,

the struct shows customFields as nil.

Not sure how I intercept and do the conversion of data to dictionary.

Update:

Able to get it by tweaking a part of the code.

if let data = value as? Data { 

   //works
if let json = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data) {
                                   try property.set(value: json, on: &self)
                               }

}

For some reason child.value is [AnyHashable:Any] is nil and this condition fails .

I have hit a performance issue with Unrealm. My Structure is:

Stint (1 instance only):
- Has 8 Lap relations (one to many)
- Lap has 3k - 6k location objects (one to many)

When I do something simple like:
` let stints = realm.objects(Stint.self)

    for stint in stints{
        if(stint.laps.count>0){
            allStints.append(stint)
        }
    }

`
It takes 2s to go through this for loop.

What is the best approach you suggest for optimizing this?

I have problem with my struct model, it's generate from google protobuf and has an enum look like this:
enum OneOf_Doc: Equatable {
case art(My_Model)
...
}
With normal enum i can make it RealmableEnum but not to this type.
How do u guys deal with this ? Thanks

Hi I have this enum with associated types

enum LogValue: Codable, RealmableEnum {
    case sugar(SugarLogCreate)
    case carb(CarbLog)
    case weight(WeightLog)

    init(from decoder: Decoder) throws {
        let container = try decoder.singleValueContainer()
        if let x = try? container.decode(SugarLogCreate.self) {
            self = .sugar(x)
            return
        }
        if let x = try? container.decode(CarbLog.self) {
            self = .carb(x)
            return
        }
        if let x = try? container.decode(WeightLog.self) {
            self = .weight(x)
            return
        }
        throw DecodingError.typeMismatch(LogValue.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type for Log Value"))
    }
    
   func encode(to encoder: Encoder) throws {
        var container = encoder.singleValueContainer()
        switch self {
        case .sugar(let x):
            try container.encode(x)
        case .carb(let x):
            try container.encode(x)
        case .weight(let x):
            try container.encode(x)
        }
    }
}

where each SugarLogCreate, CarbLog and WeightLog are structs conforming toRealmable

I get this error that tells me I have not conformed to RealmableEnums
"Type 'LogValue' does not conform to protocol 'RealmableEnum'"
and makes me put these methods in my code which I have no idea what to do with them:

func rlmValue() -> Any {
        <#code#>
    }
    
    init?(rlmValue: Any) {
        <#code#>
    }
    
    static var rawValueType: Any.Type
    

What should I do in this case?
Thank you in advance for your reply.

Hi!

I'm getting a crash in my unit test target, in Realm.registerRealmables(...) -- it loads my AppDelegate, which calls the former method.

Specifically, I am getting an EXC_BAD_ACCESS on line 53 of NominalMetadataType.swift.

More specifically, numberOfFields() is what is crashing. The field is an empty [String]

Hello,
I'm migrating my Object models to Realmable, but I have a problem with a data type I'm trying to save.

I have a data model defined like this :

` struct WorkoutRoutine: Realmable, Codable {

var id: String = UUID().uuidString
var name: String = ""
var bodyPart: String = ""

var type: String = "normal"
var globalRestTimer: Double = 0.0
var exerciseSpecificRestTimer: [Int: Double] = [0: 0.0]

var exercises: [Exercise]?
var exercisesTargetSets: [Int: Int] = [0:0]
var exercisesTargetReps: [Int: Int] = [0:0]

var createdAt: Date = Date()

static func primaryKey() -> String? {
    return "id"

}

}`

It crashes when it's trying to serialize my object as JSON. I think it's due to the fact that the keys are required to be of type NSString (when serializing with JSONSerialization), and I'm using "Int". How could they be converted automatically?

I'm not sure how to convert it to a string. When I take my model and encode it using JSONEncoder, it produces valid JSON.

Here are some screenshot of the Exception Breakpoint:

It'd be great to add Swift Package Manager compatibility to this project.

Congratulations for your amazing work.

I can not save a Swift array of custom objects.
Terminating app due to uncaught exception 'RLMException', reason: 'Property 'weather' is of type 'RLMArray<RLMWeather>' which is not a supported RLMArray object type. RLMArrays can only contain instances of RLMObject subclasses. See https://realm.io/docs/objc/latest/#to-many for more information.'
Here are my data models

struct CurrentWeather: Codable, Realmable {
    var coord: Coord?; var weather: [Weather]?
    var main: Main?; var clouds: Clouds?
    var visibility, id, dt: Int?;var wind: Wind?
    var sys: Sys?; var name: String?

    enum CodingKeys: String, CodingKey {
        case id, main
        case weatherDescription = "description"
        case icon
    }
}

// MARK: - Wind
struct Wind: Codable, Realmable {
    var speed: Double?
    var deg: Int?
}

Thanks for help!

program crashes when trying to open realm database.

		let config = Realm.Configuration(fileURL: destinationURL,
										 readOnly: false,
										 schemaVersion: 1,
										 migrationBlock: { (migration, oldSchemaVersion) in
											if (oldSchemaVersion < 1) {

											}
		})
		let realm: Realm = {
			return try! Realm(configuration: config)
		}()

_The debugger gives me a hint that it is in the object table Kanji and near column kunYomis_

struct Kanji: Realmable {
  var id: Int = 0
  var kanjiCharacter: String = ""
  var hexUnicode: String = ""
  var frequency: Int = 0
  var jlptLevel: Int = 0
  var gradeJA: Int = 0
  var strokeCount:Int = 0
  var classification: String = ""
  var kunYomis = [String]()
  var onYomis = [String]()
  var longMeanings = [String]()
  var shortMeanings = [String]()
  var radicalComponentCount: Int = 0
  var radicalComponentStrings = [String]()
  static func primaryKey() -> String?
  {
    return "id"
  }

}

This is the definition of the database as shown by RealmStudio when generating Swift model definition

class RLMKanji: Object {
    @objc dynamic var id: Int = 0
    @objc dynamic var kanjiCharacter: String = ""
    @objc dynamic var hexUnicode: String = ""
    @objc dynamic var frequency: Int = 0
    @objc dynamic var jlptLevel: Int = 0
    @objc dynamic var gradeJA: Int = 0
    @objc dynamic var strokeCount: Int = 0
    @objc dynamic var classification: String = ""
    let kunYomis = List<String>()
    let onYomis = List<String>()
    let longMeanings = List<String>()
    let shortMeanings = List<String>()
    @objc dynamic var radicalComponentCount: Int = 0
    let radicalComponentStrings = List<String>()

    override static func primaryKey() -> String? {
        return "id"
    }
}

Have been at it since yesterday, couldn't figure out what could be wrong.
Able to open the database with RealmStudio and all the data appears correct.
I'm assuming that this is not a problem with Realm itself but in my definitions but can't figure out. There are three other objects in the database as well.

I'm getting this error

Terminating app due to uncaught exception 'RLMException', reason: 'Property 'actions' is of type 'RLMArray' which is not a supported RLMArray object type. RLMArrays can only contain instances of RLMObject subclasses. See https://realm.io/docs/objc/latest/#to-many for more information.'

my property actions is defined as this:

var actions: [Action] = []

in a Realmable struct. Action is an enum that conforms to RealmableEnum

Any ideas?

i try to use enum inside an object and it's returning the following error

ENUM im trying to insert:
`

import Foundation
import Unrealm

class MikiDate : MikiDateListable, Realmable {
required init() {

}

static func == (lhs: MikiDate, rhs: MikiDate) -> Bool {
    return true
}


enum DateType: Int, Realmable {
    init() {
        self = .none
    }        
    case none = 0
    case now
    case today
    case tomorrow
    case laterDate
    case rangeDate
}

var text : String?
var checked = false
var type = DateType.none

init(type: DateType) {
    self.type = type
}

//MARK: MikiListable
func mikiText() -> String? {
    switch type {
        case .now:
            return "עכשיו - שיגיע דחוף"
        case .today:
            return "היום"
        case .tomorrow:
            return "מחר"
        case .laterDate:
            return "תאריך אחר"
        case .rangeDate:
            return "טווח תאריכים"
        default:
            return ""
    }
}

func isChecked() -> Bool {
    return checked
}

}

There's any carthage support for this framework? Thanks
