Find first element matching condition in Swift array (e.g. EKSource)

Question

I would like to find the first EKSource of type EKSourceType.Local with a \"single\"-line expression in Swift. Here is what I currently have:

Answer 1

For Swift 3 you'll need to make a few small changes to Nate's answer above. Here's the Swift 3 version:

public extension Sequence {
    func find(predicate: (Iterator.Element) throws -> Bool) rethrows -> Iterator.Element? {
        for element in self {
            if try predicate(element) {
                return element
            }
        }
        return nil
    }
}

Changes: SequenceType > Sequence, Self.Generator.Element > Iterator.Element
