In case setFrameAutosaveName does not work, then we need to manually save and load window size and position
I tried all the solutions. It can only saves the position, not the size. So we should do that manually. This is how I do it on my GifCapture app https://github.com/onmyway133/GifCapture
class MainWindowController: NSWindowController, NSWindowDelegate {
let key = "GifCaptureFrameKey"
override func windowDidLoad() {
super.windowDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(windowWillClose(_:)), name: Notification.Name.NSWindowWillClose, object: nil)
}
override func awakeFromNib() {
super.awakeFromNib()
guard let data = UserDefaults.standard.data(forKey: key),
let frame = NSKeyedUnarchiver.unarchiveObject(with: data) as? NSRect else {
return
}
window?.setFrame(frame, display: true)
}
func windowWillClose(_ notification: Notification) {
guard let frame = window?.frame else {
return
}
let data = NSKeyedArchiver.archivedData(withRootObject: frame)
UserDefaults.standard.set(data, forKey: key)
}
}
