Validation
A simple type to perform validations on Strings.
struct Validation {
var required = false
var minimumLength = 0
var maximumLength: Int?
var maximumValue: Double?
var minimumValue: Double?
var characterSet: CharacterSet?
var format: String?
}API
Making complete false will cause minimumLength, minimumValue and format to be ignored this is useful for partial validations, or validations where the final string is in process of been completed. For example when entering characters into an UITextField. With complete true all validations will be run.
func validateString(string: String, complete: Bool = true) -> BoolExamples
Required (short hand for minimum value: 1)
var validation = Validation()
validation.required = true
validation.validateString("12345") // => returns true
validation.validateString("") // => returns falseMaximum or/and minimum length
var validation = Validation()
validation.minimumLength = 5
validation.maximumLength = 6
validation.validateString("1234") // => returns false
validation.validateString("12345") // => returns true
validation.validateString("1234567") // => returns falseMinimum or/and maximum value
var validation = Validation()
validation.minimumValue = 5
validation.maximumValue = 6
validation.validateString("4") // => returns false
validation.validateString("5") // => returns true
validation.validateString("7") // => returns falseNSCharacterSet
var validation = Validation()
validation.characterSet = NSCharacterSet.decimalDigitCharacterSet()
validation.validateString("23213") // => returns true
validation.validateString("hi there") // => returns falseFormat (regex)
var validation = Validation()
validation.format = "[\\w._%+-]+@[\\w.-]+\\.\\w{2,}"
validation.validateString("[email protected]") // => returns true
validation.validateString("elvnume.co") // => returns false
validation.validateString("hi there [email protected]") // => returns falseInstallation
