Swift extensions: NSEventModifierFlags functions isSet and isNotSet

This extension makes working with the NSEventModifierFlags a little easier by hiding the verbose testing code inside a test function.

extension NSEventModifierFlags {
    func isSet(bit: NSEventModifierFlags) -> Bool {
        return self & bit == bit
    func isNotSet(bit: NSEventModifierFlags) -> Bool {
        return !isSet(bit)


After this the code to test for a modifier becomes very readable:

if theEvent.modifierFlags.isSet(.ShiftKeyMask) { ... }

Happy coding
