How to sort a 2D array in Swift?

Question

Arrays

Let's say there is an array
var arr:[(type:Int,name:String)] = []
How to sort it in swift (for example, in ascending order) by one of the fields? For example on the field type:Int?

Answer 1

Well, let's start with the fact that this is a one-dimensional array.

arr.sort { (first, second) -> Bool in
    return first.type < second.type
}

If we recall the features of clojures, then we can write it like this:
arr.sort { $0.type < $1.type }
