How to elegantly compare tuples in Swift?

Question

I do have 2 different tuples of type (Double, Double):

let tuple1: (Double, Double) = (1, 2)
let tuple2: (Double, Double) = (3, 4)

I want t

Answer 1

Similar to the answer of @JeremyP, but more generic:

func ==(lhs: (T1, T2), rhs: (T1, T2)) -> Bool {
    return lhs.0 == rhs.0 && lhs.1 == rhs.1
}

func ==(lhs: (T1, T2, T3), rhs: (T1, T2, T3)) -> Bool {
    return lhs.0 == rhs.0 && lhs.1 == rhs.1 && lhs.2 == rhs.2
}

func ==(lhs: (T1, T2, T3, T4), rhs: (T1, T2, T3, T4)) -> Bool {
    return lhs.0 == rhs.0 && lhs.1 == rhs.1 && lhs.2 == rhs.2 && lhs.3 == rhs.3
}
