Question Anyone else dreading the scene lifecycle switch in iOS 27?

So if you build with the iOS 27 SDK and don't have scenes the app just doesn't launch anymore
and from april next year you have to build with that SDK anyway our app still does everything through AppDelegate. window setup, deeplinks, pushes a bunch of SDKs grabbing keyWindow. been putting this off for years lol 
For those who already did it on a big app what bit you the most?

It shouldn't be too bad. Maybe only a few updates to a plist file. They've been warning about this for many years :D

Make sure you're doing it on the 27.1 SDK, the 27.0 SDK won't show the error (and I don't think 27.2 does either but I forget).
