Separation of function declaration and definition in Swift

Question

I\'m having a look at the new Swift. I come from C, C++, Objective-C... I notice that in swift is not possible (?) to separate the declaration and the definition of function

Answer 1

About the best we can do is use protocols as Implementation declarations and mark all private methods:

protocol TestInterface {
    var propertyPublic1: String { get }
    func funcPublic1() -> Int
}

class Test : TestInterface {
    var propertyPublic1: String = "text."
    func funcPublic1() -> Int {return 754}

    private var propertyPrivate1: Int = 5678
    private func funcPrivate1() -> Int {return 334}
}

var t = Test()
let propPublic1 = t.propertyPublic1

The problem is that it is not provided as a standard idiom and the naming is unfortunate, I have just appended "Interface" to the class name.
