Honour

Validation library for iOS inspired by Respect/Validation.

Validator.mustBe(Uppercase()).andMust(StartsWith("F")).validate("FOOBAR")

Usage

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.

Validate

func validate(value: String) -> Bool

let validator = Validator().addRule(Uppercase()).addRule(StartsWith("J"))
validator.validate("JEAN") // true
validator.validate("PIMENTEL") // false

Assert

func assert(value: String) -> (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")]

Check

func check(value: String) -> (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")
