This is a small pitch which I will abandon if there is not much appetite for such improvement. ;)
I would like to propose an improvement to an initializer of all collection types that provide: init(repeating repeatedValue: Element, count: Int). This change is meant to support reference type initialization on each iteration of the internal for-loop rather than copying the same references n times. The change would be really straightforward and should not break existing code, except that the behavior would change for class types. Instead of: init(repeating repeatedValue: Element, count: Int) let threeViews = Array(repeating: UIView(), count: 3) // contains 1 view 3 times we would have: init(repeating repeatedValue: @autoclosure () -> Element, count: Int) This simple change would allow us to construct an array of different objects instead of an array with n references to the same object. let threeViews = Array(repeating: UIView(), count: 3) // contains 3 different views
