Big Sur breaks code

[polymerchm]

The following code (use to position and size the main window after launch) now crashes

delay(0.1) {
let ns = self.window?.nsWindow
Dynamic(ns!).setFrame(CGRect(200,200,1200,800), display: true)
let frame = Dynamic(ns!).frame.asCGRect!
let size = frame.size
Dynamic(ns!).setAspectRatio(CGSize(1.0, size.height/size.width))

}

with the following error

Yeah, hostWindowForUIWindow() now returns UINSWindowProxy on macOS 11. We need to call UINSWindowProxy.attachedWindow to get the actual window:

extension UIWindow {
    var nsWindow: NSObject? {
        var nsWindow = Dynamic.NSApplication.sharedApplication.delegate.hostWindowForUIWindow(self)
        if #available(macOS 11, *) {
            nsWindow = nsWindow.attachedWindow
        }
        return nsWindow.asObject
    }
}

Let me know if it works for you.

Adding the attachedWindow works on BigSur, but if #available(macOS 11, *) also resolves to true on Catalina.

I ended up with this for now:

extension UIWindow
{
    public var nsWindow: Dynamic
    {
        if ProcessInfo.processInfo.isOperatingSystemAtLeast(OperatingSystemVersion(majorVersion: 11, minorVersion: 0, patchVersion: 0))
        {
            return Dynamic.NSApplication.sharedApplication.delegate.hostWindowForUIWindow(self).attachedWindow
        }
        else
        {
            return Dynamic.NSApplication.sharedApplication.delegate.hostWindowForUIWindow(self)
        }
    }
}
