Converting a closure to an @escaping closure in Swift 3

Escaper.swift

func makeEscaping<Parameters,Result>(_ closure: (Parameters) -> Result) -> (Parameters) -> Result {
	func cast<From,To>(_ instance: From) -> To {
		return (instance as Any) as! To
	}

	return cast(closure)
}


// Example

import UIKit

extension UIView {
	static func noescapeAnimate(withDuration duration: TimeInterval, changes: () -> ()) {
		animate(withDuration: duration, animations: makeEscaping(changes))
	}
}

Fixed to support builds having Whole Module Optimization enabled.
