I'm pretty much solely a C++/C# on Windows developer (with some Android/Unix/Linux a while ago).
I know that on Windows I can write an app that sends keyboard commands and invoke menu commands from one running executable to another. Is this possible on IOS? I.e. Could I have one app invoking commands on another. Specifically without needing a code change in the receiving app? E.g. Send a hotkey to invoke a command.
Any API(s) I could look at to get started? Could this be done with QT or would I need a Mac and XCode.
