QHValidator

• Input validator for Swift
• 94% Code Coverage
• Declarative Validator
• Functional Programming

Validating an Integer

let numberValidator = Validator<Int>().lesserThan(value: 150).greaterOrEqualsThan(value: 10)
let result = try numberValidator.validate(value: 50)

Validating a String

let emailValidator = Validator<String>().notEmpty().maxLength(length: 55).isEmailAddress()
let result = try emailValidator.validate(value: "yourmail@mail.com")

Validating using the combine extension

let emailValidator = Validator<String>().notEmpty().maxLength(length: 55).isEmailAddress()
let result = emailValidator.validateAsPublisher(value: "yourmail@mail.com")

Create your custom validation rule

Validator has an add method where you set a validation rule

func add(rule: @escaping (Input) throws -> Bool) -> Validator<Input>

See how it works:

let emailValidator = Validator<String>().notEmpty().maxLength(length: 55).isEmailAddress().add { string in 
  return string.count == 25
}
let result = try emailValidator.validate(value: "yourmail@mail.com")
