Tapping Drop on iOS 17, built with Xcode 15, triggers EXC_BAD_ACCESS

[yumemi-ajike]

Hi,

EXC_BAD_ACCESS occurs when tapping 'Drop' in the UIKitExample app built with Xcode 15 RC, when running on iOS 17.

It seems to be accessing WindowController.preferredStatusBarStyle in an infinite loop.
Drop.action does not be firing.
This does not occur on iOS 16.

Drops_Loop.mov

Thanks for the great framework!

I found the addition of a workaround for a UIKit bug in version 1.3.0.

Removing these lines can avoid the problem on iOS 17.

However, I don't know which version of iOS the workaround was implemented for, so I can't create an 'if' statement.

I just debugged it, looks like this line is returning the WindowViewController itself:

    let topViewController = windowScene?.windows.first(where: \.isKeyWindow)?.rootViewController?.top

    let check = topViewController == self // true

which is causing an infinite loop (StackOverflow) when trying to access the preferredStatusBarStyle on it:

    return topViewController?.preferredStatusBarStyle
      ?? windowScene?.statusBarManager?.statusBarStyle
      ?? .default

I wonder what's the goal of this code 🤔.
Judging form the issue linked in the code, it looks like the color of the status bar changes when the Drop appears. If that's the case I guess we should get the preferredStatusBarStyle from the view controller behind the one on top.
