Adding any two numberic tuples in swift

Question

I have created one function to add tuples which looks like (Int, Int).

func + (x: (T, T), y: (T, T)) -> (T, T) {
    return (x.0 + y.0, x.1         


        

Answer 1

You can use the Array solution as suggested by @Cristik or you can also make use of closure returning variadic function like:

func add(_ a: T...) -> (_ b: T...) -> [T] {
    return { (b: T...) -> [T] in
        return zip(a, b).map { $0.0 + $0.1 }
    }
}

let sum = add(1, 2,3)(4, 5, 6)

print(sum)
