Tuples

let coord = (3, 5)

or

let coord:(Int, Int) = (3, 5)

//playground result:(.0 3, .1 5)

//To access elements of the tuple:

coord.0 //3

coord.1 //5

or

let (x, y) = coord

x //3

y //5

or use underscores to ignore elements of the tuple:

let (_,theYvalue) = coord

theYvalue //5

Named tuple

let coord = (X: 3, Y: 5)

coord.X //3

coord.Y //5

or the explicit form:

let coord:(myX:Int, myY:Int) = (3, 5)

coord.myX //3

coord.myY //5
