First image is a "cold" start - starting app by tapping the icon Second image is a start from XCode with "Run" option (Cmd+R) where debugger is linked Difference is: Push token changed (7 line), start observing (9 line). liveactivitysd generates token before we reach pushToStartTokenUpdates loop - we losing token Start observing (line 2), push token changed (last line). Everything is okay The question is: how is this possible (case 1)?

Update: Just need to use another register function, that have nib as a first argument func register( _ nib: UINib?, forCellWithReuseIdentifier identifier: String )

My custom cell, defined in .xib initialized with init(frame: CGRect) instead of init?(coder: Decoder) So the original problem still persist on my side
