cocoa - Simulate keypress using Swift

Question

I'm searching for a way to simulate keystrokes in OSX. I found another solution (Simulate keypress for system wide hotkeys) using Objective-C, but i need to do it with Swift. How can i adapt CGEventCreateKeyboardEvent?

Answer 1

Working with Swift 3

let src = CGEventSource(stateID: CGEventSourceStateID.hidSystemState)

let cmdd = CGEvent(keyboardEventSource: src, virtualKey: 0x38, keyDown: true)
let cmdu = CGEvent(keyboardEventSource: src, virtualKey: 0x38, keyDown: false)
let spcd = CGEvent(keyboardEventSource: src, virtualKey: 0x31, keyDown: true)
let spcu = CGEvent(keyboardEventSource: src, virtualKey: 0x31, keyDown: false)

spcd?.flags = CGEventFlags.maskCommand;

let loc = CGEventTapLocation.cghidEventTap

cmdd?.post(tap: loc)
spcd?.post(tap: loc)
spcu?.post(tap: loc)
cmdu?.post(tap: loc)
