I'm pretty new to Swift and I'm having some trouble implementing alerts into my SpriteKit game. Well, it works however it keeps giving warnings:
2022-06-03 02:04:04.465264+0100 Project14[57880:10648157] [LayoutConstraints] Changing the translatesAutoresizingMaskIntoConstraints property of a UICollectionViewCell that is managed by a UICollectionView is not supported, and will result in incorrect self-sizing.

How do I get rid of this warnings? Thanks.
let alert = UIAlertController(title: "title", message: "message", preferredStyle: UIAlertController.Style.alert)
alert.addTextField { field in
field.placeholder = "Input your name"
field.isSecureTextEntry = false
field.textAlignment = .left
}
alert.addAction(UIAlertAction(title: "OK", style: .default) { _ in
print("ok")
})
alert.addAction(UIAlertAction(title: "Cancel", style: .default) { _ in
print("cancel")
})
view?.window?.rootViewController?.present(alert, animated: true)
}
I cannot use just present(alert, animated: true). In this case I get compiler error - "Value of type 'SceneMenu' has no member 'present'"

Hi. I'm pretty new to Swift and I'm having some trouble displaying UITextField in SpriteKit. Init() in SceneMenu will not display the UITextField, while using function showTextField() with touchesBegan() works. How can I display UITextField without the user clicking the button Show TextField?
GameViewController.swift:
class GameViewController: UIViewController {
override func viewDidLoad() {
let scene = SceneMenu(size: view.frame.size)
scene.scaleMode = .aspectFill
scene.backgroundColor = .white
let view = view as! SKView
view.presentScene(scene)
}
}
SceneMenu.swift:
class SceneMenu: SKScene {
override init(size: CGSize) {
super.init(size: size)
let btnAlert = SKLabelNode(text: "Show TextField")
btnAlert.name = "btn_text"
btnAlert.fontSize = 20
btnAlert.fontColor = SKColor.blue
btnAlert.fontName = "Avenir"
btnAlert.position = CGPoint(x: size.width / 2, y: size.height / 2)
addChild(btnAlert)
let textFieldFrame = CGRect(origin: CGPoint(x: 100, y: 300), size: CGSize(width: 200, height: 30))
let textField = UITextField(frame: textFieldFrame)
textField.backgroundColor = SKColor.blue
textField.placeholder = "Type name"
view?.addSubview(textField)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func showTextField() {
let textFieldFrame = CGRect(origin: CGPoint(x: 100, y: 100), size: CGSize(width: 200, height: 30))
let textField = UITextField(frame: textFieldFrame)
textField.backgroundColor = SKColor.blue
textField.placeholder = "Type name"
view?.addSubview(textField)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
if let touch = touches.first {
let location = touch.location(in: self)
let action = atPoint(location)
if action.name == "btn_text" {
showTextField()
}
}
}
}
