StringInputValidator

StringInputValidator provides a convenient way to test a given string against a validator. A validator can be as simple the RegularExpressionValidator.numeric which checks wether the string contains numeric values only. Or a complex validator if you combine length/format validation using a composite validator.

How to use StringInputValidator

	let lengthVal = LengthValidator(lengthLimit: 5)
    let emptyVal = NotEmptyValidator()
     let numVal = RegularExpressionValidator.numeric
        
    let compVal = CompositeValidator(validators: lengthVal, emptyVal, numVal)
    let res = compVal.validate(value: "absdefgh")

    // ask for validity
    res.isValid()

    // or 
    if case let .invalid(error) = res {
        error.contains(.invalidFormat)
        error.contains(.lengthExceeded)
    } else {}

    // check the description [InvalidFormat, LengthExceeded, LengthMismatch]
    let string = error.description

Installation

Installation with Carthage
