I like the idea very much. One idea for improvement: article might mention that file must be made executable - it took me a while until I realised this (probably not to everyone) obvious fact.

java -jar ./static-app.jar --build
[+] SEVERE: Path to Emacs not valid.

It's possible I'm misunderstanding this code:

for case let (label?, anyValue) in mirror.children {
    if let value = anyValue as? AnyObject {
        managedObject.setValue(child, forKey: label)
    } else {
        throw SerializationError.UnsupportedSubType(label: label)
    }
}

Shouldn't that be "managedObject.setValue(value, forKey: label)"?

Hi there,

Great article.

Could it be that you made a little mistake here:

guard oldData == newData else { return }

Shouldn't it be:

guard oldData != newData else { return }

For some reason isNone: Bool and isSome: Bool don't work. I get error:

Cannot convert value of type 'Optional' to expected argument type '_?'

Tested on Xcode 9.2 (9C40b), Swift 4.0

However, this version compiles without problem:

var isNone: Bool {
        switch self {
        case .none:
            return true
        default:
            return false
        }
    }

var isSome: Bool {
        switch self {
        case .some(_):
            return true
        default:
            return false
        }
    }

Unfortunately, I don't know the root cause.

In this code example:

typealias Config = (RAM: Int, CPU: String, GPU: String)

// Each of these takes a config and returns an updated config
func selectRAM(_ config: Config) -> Config {return (RAM: 32, CPU: config.CPU, GPU: config.GPU)}
func selectCPU(_ config: Config) -> Config {return (RAM: config.RAM, CPU: "3.2GHZ", GPU: config.GPU)}
func selectGPU(_ config: Config) -> Config {return (RAM: config.RAM, CPU: "3.2GHZ", GPU: "NVidia")}

enum Desktop {
   case Cube(Config)
   case Tower(Config)
   case Rack(Config)
}

let aTower = Desktop.Tower(selectGPU(selectCPU(selectRAM((0, "", "") as Config))))

Why do the select functions (selectRAM, selectCPU, selectGPU) set the value of the associated values? It would make more sense if the functions took in the new value and the config and then set the new value based on the input.

Also, I'm not clear on what "select" means here. The word "set" or "update" make more sense to me based on my understanding of these functions.

Hi,
We are SwiftGG Chinese translation team, we are now translating high quality English swift blogs into Chinese to help native iOS developer better learning the swift language.

Thanks for your high quality blogs, and we've translated most of the blogs into Chinese. I'm wondering if you would like to add the translation link to the blog article. Or if you wish, you can tell us where to insert the link, then we can add the link ourselves and create a pull request.

Here are all the translated blogs: http://swift.gg/tags/APPVENTURE/
