SOLVED: How can I programmatically enter text to an arbitrary application/first-responder?

Forums > macOS

I want to make a little tool that can enter some text (like a snippet manager) into the app that is focused. How can I do that?


At the moment I am thinking CGEventCreateKeyboardEvent. I am guessing that is the way to go, here?


This works:

let text = "\(Date())"
let utf16Chars = Array(text.utf16)

let event1 = CGEvent(keyboardEventSource: nil, virtualKey: 0x31, keyDown: true);
event1?.flags = .maskNonCoalesced
event1?.keyboardSetUnicodeString(stringLength: utf16Chars.count, unicodeString: utf16Chars)
event1?.post(tap: .cghidEventTap)

let event2 = CGEvent(keyboardEventSource: nil, virtualKey: 0x31, keyDown: false);
event2?.flags = .maskNonCoalesced
event2?.post(tap: .cghidEventTap)
