Swift App runs but no buttons appear - swift

Question

I wrote a Swift app but only the window appears when it runs. I can't see any buttons.
Here is my code... I've tried removing the .white attribute thinking maybe it was hidden behind a layer. Nothing.

Answer 1

Three errors:
First, you are overriding viewDidLoad() and defining another viewDidLoad() inside of it.
Your code:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
func viewDidLoad() {
super.viewDidLoad()
}
}
Should just look like this:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
Second, you are overriding viewDidAppear but never calling super.
Your code:
override func viewDidAppear() {
// Window Properties, including solid colour, lack of resize, movable by background.
view.window?.titlebarAppearsTransparent = true
view.window?.backgroundColor = NSColor.white
view.window?.styleMask.remove(.resizable)
view.window?.isMovableByWindowBackground = true
}
Should look like this:
override func viewDidAppear() {
super.viewDidAppear()
// Window Properties, including solid colour, lack of resize, movable by background.
view.window?.titlebarAppearsTransparent = true
view.window?.backgroundColor = NSColor.white
view.window?.styleMask.remove(.resizable)
view.window?.isMovableByWindowBackground = true
}
Third, you are overriding the IPAdress didSet and then setting it again. This will cause an infinite loop. You are also comparing a textField to nil, which it will never be, because it's a NSTextField!, instead of checking whether it's empty or not. I can't really make sense of what you're trying to achieve here but you should rip all this overriding nonsense out until you can clearly formulate your intention.
