Usage

Use the generic function handle(_:) to wrap some code that can throw an NSException.

do {

    let result = try handle { () -> String in

        // Some invocation that can throw an NSException

        return "OK"
    }

    // The type of `result` is `String`.

} catch let exception as NSException {

    // Handle the exception

} catch {

    // Handle some other error thrown.

}
