swift - How to simulate mouse click from Mac App to other Application

Question

I am trying to simulate mouse click on iphone simulator from macos App for that I am using CGEvents .

the process id is 33554 for iPhone simulator

let point = CGPoint(x: 500  , y:300)
let eventMouseDown = CGEvent(mouseEventSource: nil, mouseType: .leftMouseDown, mouseCursorPosition: point, mouseButton: .left)
let eventMouseUp = CGEvent(mouseEventSource: nil, mouseType: .leftMouseUp, mouseCursorPosition: point, mouseButton: .left)
eventMouseDown?.postToPid(33554)
eventMouseUp?.postToPid(33554)

I have also noticed that It simulates mouse click when ios simulator window is focused and only works for this toolbar but not for the simulator for example if I change CGPoint to (0,30) it will click on Simulator option

but when I am giving CGPoints to click app inside iOS Simulator its not working

However, I am able to post Keyboard Event to Simulator using

let keyboardDown = CGEvent(keyboardEventSource: nil, virtualKey: 6, keyDown: true)
let keyboardUp = CGEvent(keyboardEventSource: nil, virtualKey: 6, keyDown: false)
keyboardDown?.postToPid(33554)
keyboardUp?.postToPid(33554)

First of if you look at postToPid there is no documentation at all

So not even sure if it is suppose to work and if yes then when and when not. But you can post the event directly to screen using below code

//
//  main.swift
//  mouseplay

let source = CGEventSource.init(stateID: .hidSystemState)
let position = CGPoint(x: 75, y: 100)
let eventDown = CGEvent(mouseEventSource: source, mouseType: .leftMouseDown, mouseCursorPosition: position , mouseButton: .left)
let eventUp = CGEvent(mouseEventSource: source, mouseType: .leftMouseUp, mouseCursorPosition: position , mouseButton: .left)


eventDown?.post(tap: .cghidEventTap)

//eventDown?.postToPid(71028)
usleep(500_000)
//eventUp?.postToPid(71028)
eventUp?.post(tap: .cghidEventTap)

print("Hello, World!")

You can see it working also
