What do you make of this? I'm still trying to understand the performance hitches while scrolling the timeline in @IceCubesApp, and I can't seem to understand where it's coming from apart from the general "Well, SwiftUI is slow for complex view hierarchy."

@dimillian @IceCubesApp You are not using Hitches template in your screenshot. This is SwiftUI template. Is Hitches template work for you? My experience is that it is broken. I have reported a bug for Apple.

@jurajantas I can see hitches, the thing is that there is nothing I can really learn about them

@dimillian it takes time. Just wait. If it crashes on 15.4 try on Xcode 16 beta.

@jurajantas Oh how interesting!

@dimillian I see you have same result. No graphs for Hitches if you expand first row. It is shame because this is the tool for telling what is slow.
