windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead

[ToddHoff]

First, thanks for this code. It's great and has been a great help.

In new releases there's a new warning in the build:

func setFrame() {

This line has this warning: 'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead:
let safeAreaInsets = UIApplication.shared.windows.first(where: { $0.isKeyWindow })?.safeAreaInsets ?? .zero
let frame = UIScreen.main.bounds.inset(by: safeAreaInsets)

    let adSize = GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(frame.width)
    
    self.width = adSize.size.width
    self.height = adSize.size.height
}

After a lot of research I didn't find a clear answer. I fixed it with:

func getSafeArea()-> UIEdgeInsets {

    let keyWindow = UIApplication
        .shared
        .connectedScenes
        .flatMap { ($0 as? UIWindowScene)?.windows ?? [] }
        .first { $0.isKeyWindow }
    
    return (keyWindow?.safeAreaInsets)!
}

func setFrame() {
    
     let safeAreaInsets = getSafeArea()
    let frame = UIScreen.main.bounds.inset(by: safeAreaInsets)
    
    let adSize = GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(frame.width)
    
    self.width = adSize.size.width
    self.height = adSize.size.height
     
}

This fixes the warning and seems to mostly work, but I get a few crashes in getSafeArea() with an unwrapped nil error. I can see why that would be, but since you actually know what you're doing, I'm just wondering if there's a better fix?

thanks

I fixed it this way and it seems to be working alright for me.

        let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene
        let safeAreaInsets = windowScene?.windows.first(where: { $0.isKeyWindow })?.safeAreaInsets ?? .zero
