A framework and Xcode plugin for generating Lenses using SourceKitten

Just give it the model files and it will generate Simple Lenses based on that:

Example:

struct Model {
  let string: String
  let int: Int
  let float: Float
  let double: Double
  let array: [Any]
  let dictionary: [String: Any]
}

Output:

extension Model {
  static let stringLens = Lens<Model, String>(
    get: { \$0.string },
    set: { Model(string: \$0, int: \$1.int, float: \$1.float, double: \$1.double, array: \$1.array, dictionary: \$1.dictionary) }
  )

  static let intLens = Lens<Model, Int>(
    get: { \$0.int },
    set: { Model(string: \$1.string, int: \$0, float: \$1.float, double: \$1.double, array: \$1.array, dictionary: \$1.dictionary) }
  )

  static let floatLens = Lens<Model, Float>(
    get: { \$0.float },
    set: { Model(string: \$1.string, int: \$1.int, float: \$0, double: \$1.double, array: \$1.array, dictionary: \$1.dictionary) }
  )

  static let doubleLens = Lens<Model, Double>(
    get: { \$0.double },
    set: { Model(string: \$1.string, int: \$1.int, float: \$1.float, double: \$0, array: \$1.array, dictionary: \$1.dictionary) }
  )

  static let arrayLens = Lens<Model, [Any]>(
    get: { \$0.array },
    set: { Model(string: \$1.string, int: \$1.int, float: \$1.float, double: \$1.double, array: \$0, dictionary: \$1.dictionary) }
  )

  static let dictionaryLens = Lens<Model, [String: Any]>(
    get: { \$0.dictionary },
    set: { Model(string: \$1.string, int: \$1.int, float: \$1.float, double: \$1.double, array: \$1.array, dictionary: \$0) }
  )
}
