Please replace this with the steps to reproduce the behavior.

1. I run my app FROM xCode (it's important) and login them (main screen with a lot of skeleton views)
2. Turn my app in Background and wait some time (pin code after that appear)
3. Run my app from Push notification. My main screen is deinited, use see pin screen.
4. User enter pin screen
5. User see main screen with a lot of skeleton
6. Crash appear.

If i make this steps in iOS simulator 17.2, all work fine. If i run app from simulator as normal app (not from xCode), all work fine too

Expected result:

All work fine

Actual result:

Crash

traitCollectionDidChange

traitCollectionDidChange(_:) Deprecated

Use registerForTraitChanges(_:handler:) or registerForTraitChanges(_:target:action:) instead.

[duoshankui]

Hi, I have the same problem. How do I solve it? You said to use registerForTraitChanges(:handler:) instead of traitCollectionDidChange(:) , how do I do that?

[pnzr00t]

Hi, no, i'm not fully solved it, but i create deep link opened with delay, and it's help me. (i think in my case it was some conflict between show VC and show skeleton)
