Tailor 3.0.0

Tailor Swift logo

A super fast & convenient object mapper tailored for your needs.

Mapping objects to arrays or dictionaries can be a really cumbersome task, but those days are over. Tailor features a whole bunch of nifty methods for your model sewing needs.

Mapping properties

Tailor features property, relation(s) mapping for both struct and class objects.

Struct

struct Person: Mappable {

  var firstName: String? = ""
  var lastName: String? = ""

  init(_ map: JSONDictionary) {
    firstName <- map.property("first_name")
    lastName  <- map.property("last_name")
  }
}

let dictionary = ["first_name" : "Taylor", "last_name" : "Swift"]
let model = Person(dictionary)

Class

class Person: Mappable {

  var firstName: String? = ""
  var lastName: String? = ""

  required convenience init(_ map: [String : AnyObject]) {
    self.init()
    firstName <- map.property("first_name")
    lastName  <- map.property("last_name")
  }
}

let dictionary = ["first_name" : "Taylor", "last_name" : "Swift"]
let model = Person(dictionary)

Object mapping

struct Person: Mappable {

  var firstName: String? = ""
  var lastName: String? = ""
  var spouse: Person?

  init(_ map: JSONDictionary) {
    firstName <- map.property("first_name")
    lastName  <- map.property("last_name")
    spouse    <- map.relation("spouse")
  }
}

let dictionary = [
  "first_name" : "Taylor",
  "last_name" : "Swift",
  "spouse" : ["first_name" : "Calvin",
              "last_name" : "Harris"]
]
let model = Person(dictionary)

Mapping objects

struct Person: Mappable {

  var firstName: String? = ""
  var lastName: String? = ""
  var spouse: Person?
  var parents = [Person]()

  init(_ map: JSONDictionary) {
    firstName <- map.property("first_name")
    lastName  <- map.property("last_name")
    spouse    <- map.relation("spouse")
    parents   <- map.relations("parents")
  }
}

let dictionary = [
  "first_name" : "Taylor",
  "last_name" : "Swift",
  "spouse" : ["first_name" : "Calvin",
              "last_name" : "Harris"],
  "parents" : [
             ["first_name" : "Andrea",
              "last_name" : "Swift"],
              ["first_name" : "Scott",
              "last_name" : "Swift"]
  ]
]
let model = Person(dictionary)

SafeMappable

struct ImmutablePerson: SafeMappable {
  let firstName: String
  let lastName: String
  let spouse: Person
  let parents = [Person]()

  init(_ map: JSONDictionary) throws {
    firstName = try <-map.property("firstName")
    lastName = try <-map.property("lastName")
    spouse = try <-map.relationOrThrow("spouse")
    parents = try <-map.relationsOrThrow("parents")
  }
}

let immutablePerson: ImmutablePerson
do {
  immutablePerson = try TestImmutable(["firstName" : "foo" , "lastName" : "bar"])
} catch {
  print(error)
}

Transforms

struct Person: Mappable {

  var firstName: String? = ""
  var lastName: String? = ""
  var spouse: Person?
  var parents = [Person]()
  var birthDate = NSDate?

  init(_ map: JSONDictionary) {
    firstName <- map.property("first_name")
    lastName  <- map.property("last_name")
    spouse    <- map.relation("spouse")
    parents   <- map.relations("parents")
    birthDate <- map.transform("birth_date", transformer: { (value: String) -> NSDate? in
      let dateFormatter = NSDateFormatter()
      dateFormatter.dateFormat = "yyyy-MM-dd"
      return dateFormatter.dateFromString(value)
    })
  }
}

let dictionary = [
  "first_name" : "Taylor",
  "last_name" : "Swift",
  "spouse" : ["first_name" : "Calvin",
              "last_name" : "Harris"],
  "parents" : [
             ["first_name" : "Andrea",
              "last_name" : "Swift"],
              ["first_name" : "Scott",
              "last_name" : "Swift"]
  ],
  "birth_date": "1989-12-13"
]
let model = Person(dictionary)
