How to use this library to programmatically create macOS Apps

[efgee]

Congratulation to this gem of library.
I would like to use it to programmatically create macOS apps with Go.

How can I make this work?
The code below crashes as soon the NewNSWindow call is done.
It looks like it has something to do with NSRectMake.

Thanks in advance.
`

package main

import (
"github.com/mkrautz/objc"
. "github.com/mkrautz/objc/Foundation"
. "github.com/mkrautz/objc/AppKit"
"runtime"
"fmt"
)

type ApplicationDelegate struct {
objc.Object
}

func InitApplicationDelegate() ApplicationDelegate {
return ApplicationDelegate{objc.GetClass("ApplicationDelegate").Alloc().Init()}
}

func main() {
defer runtime.LockOSThread()
pool := NewNSAutoreleasePool()
defer pool.Release()

app := NSSharedApplication()
del := InitApplicationDelegate()
app.SetDelegate(del)
app.SendMsg("setActivationPolicy:", 0)

rect := NSRectMake(0, 0, 500, 500)
window := NewNSWindow(rect, NSWindowStyleMaskTitled, NSBackingStoreBuffered, false)
window.SendMsg("display")
window.SendMsg("makeKeyAndOrderFront:", app)

fmt.Println("Still OK!")

app.SendMsg("activateIgnoringOtherApps:", true)
app.Run()
pool.Release()

}`

Not sure why the code is weirdly displayed on GitHub...

To fix the code display, you need to surround it in triple backticks ```

There is an example in the repo that shows how to create a simple app delegate in go: https://github.com/mkrautz/objc/blob/master/demo/demo.go#L17-L19
