Is it possible to access a shadowed top level function in Swift?

Question

I was trying to write an Int extension to clamp an Int to a specific range, like this:

extension Int {
  func clamp(left: Int, right: Int) -> Int {
    re         


        

Answer 1

You can prepend the module name, in this case Swift:

extension Int {
    func clamp(left: Int, right: Int) -> Int {
        return Swift.min(Swift.max(self, left), right)
    }
}

And just for fun: You get the same result with

extension Int {
    func clamp(left: Int, right: Int) -> Int {
        return (left ... right).clamp(self ... self).start
    }
}

using the clamp() method from ClosedInterval.

Answer 2

You could create a function myMin<T>(a: T, b: T) that calls min and use that in your extension.
