tomekc / Optional+getOrElse.swift

Last active October 28, 2016 17:29

Add .getOrElse() method to Swift's Optional<T>, to unwrap value with fallback to default value. Idea borrowed from Scala language.

	// An extension to Optional type:
	// getOrElse() will return optional's value if exists, otherwise the default value provided as argument will be returned.
	//
	// Note: Since Xcode6 beta 5, you can use '??' operator.
	//

	extension Optional {
	func getOrElse(val:T) -> T {
	if self != nil {
