Elegant `bounded` methodology in Swift

Question

I\'m looking for a more elegant way to create bounded limiters for numbers, primarily to be used in setters. There are plenty of techniques for determining whether a value falls

Answer 1

I would generalize this extension to any Comparable, so that more types can benefit from it. Also, I would change the parameter to be a ClosedRange rather than two separate Self parameters, because that's the more common way of handling ranges in Swift. That'll come in especially handy when dealing with array indices.

extension Comparable {
    func clamped(to r: ClosedRange) -> Self {
        let min = r.lowerBound, max = r.upperBound
        return self < min ? min : (max < self ? max : self)
    }
}

// Usage examples:
10.clamped(to: 0...5) // => 5
"a".clamped(to: "x"..."z") // => "x"
-1.clamped(to: 0...1) // => 0
