Hi,
I realize that updating strokeColor property on the UIButton configuration after dark/light mode changes is not working correctly. Here is a sample code to explain problem.
class ViewController: UIViewController {
var configuration = UIButton.Configuration.plain()
private lazy var button: UIButton = {
let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle("Test Button", for: .normal)
configuration.background.strokeColor = borderColor
configuration.background.backgroundColor = borderColor
configuration.background.strokeWidth = 10
button.configuration = configuration
return button
}()
var borderColor: UIColor {
UIColor.dynamic(light: UIColor.systemPink, dark: UIColor.green)
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(button)
NSLayoutConstraint.activate([
button.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 30),
button.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -30),
button.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 100),
button.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -100)
])
}
}
extension UIColor {
static func dynamic(light: UIColor, dark: UIColor) -> UIColor {
return UIColor { traitCollection -> UIColor in
traitCollection.userInterfaceStyle == .light ? light : dark
}
}
}
The code above is quite simple I have a button and it has UIButtonConfiguration with backgroundColor and strokeColor functionalities. Both backgroundColor and strokeColor use the same borderColor. I also have a simple extension to generate dynamic color for active trait collection. So in theory whenever I change the active appearance UIButton Configuration should fetch the dynamic color based on the active trait (pink for light, green for dark). But here are the results.
First app install on dark mode
After changing trait to light mode
After changing trait to dark mode again
As you can see I am using the same color for both the background and stroke they are messed up after the first trait change. Somehow configuration.background.strokeColor gets incorrect trait color. I debug it and check it borderColor returns the correct color. Also, this code is working on Xcode 14.3.1 perfectly. Somehow the strokeColor functionality seems to be broken on Xcode 15.
Does anyone have any idea how to work around it?

I am checking the Push Notification Console of Cloudkit to understand my apps push delivery metrics. There are nice metrics in there to see push sends and discards. But I couldn't see any metric to understand "How many of the users opened the notiifications I send". Is there any way me to understand this statistic?
Also can we export this metrics without logging in to CloudKit like an API request?
