Honour 1.1.1

  • By
  • Jean Pimentel


Validation library for iOS inspired by Respect/Validation.


:exclamation: If you want to use this library in Objective-C classes, check HonourBridge repo.


Single Validation

let username = "jeanpimentel"
Lowercase().validate(username) // true

Chained Validation

It is possible to use validators in a chain.

let v = Validator.addRule(Lowercase()).addRule(NoWhitespace()).addRule(Length(min: 3, max: 60))
v.validate("jeanpimentel") // true

Syntax sugar

It is possible to use some syntax tricks to be highly expressive.

let v = Validator.mustHave(Length(min: 3, max: 60)).and(NoWhitespace()).andMustBe(Lowercase())
v.validate("jeanpimentel") // true

Granularity control

We have 3 validation methods

  • validate() - returns true or false
  • assert() - returns a tuple with true/false and all errors, if any.
  • check() - returns a tuple with true/false and the first error, if any.


func validate(value: AnyObject) -> Bool
let validator = Validator().addRule(Uppercase()).addRule(StartsWith("J"))
validator.validate("JEAN") // true
validator.validate("PIMENTEL") // false


func assert(value: AnyObject) -> (isValid: Bool, invalidRules: Array<Rule>)
let validator = Validator().addRule(Uppercase()).addRule(StartsWith("J"))

let result = validator.assert("JEAN")
result.isValid      // true
result.invalidRules // [] (empty)

let result = validator.assert("Jean")
result.isValid      // false
result.invalidRules // [Uppercase()]

let result = validator.assert("Felipe")
result.isValid      // false
result.invalidRules // [Uppercase(), StartsWith("J")]


func check(value: AnyObject) -> (isValid: Bool, invalidRule: Rule?)
let validator = Validator().addRule(Uppercase()).addRule(StartsWith("J"))

let result = validator.check("JEAN")
result.isValid     // true
result.invalidRule // nil

let result = validator.check("Felipe")
result.isValid     // false
result.invalidRule // Uppercase()

let result = validator.check("FELIPE")
result.isValid     // false
result.invalidRule // StartsWith("J")
