I finally figured out the cause for the problem with bad responsiveness: We have an .onTapGesture(count: 4) for debugging purposes, and that is what is causing an delay/lag/freeze for regular taps. I guess .onTapGesture(count:) has regressed in xcode 16 and somehow now causes lag for regular inputs when wrapped in a ontapgesture? It worked perfectly in Xcode 15.4. We also have the same problem with drag gestures in a scrollview that is discussed here: https://forums.developer.apple.com/forums/thread/760035 So maybe all custom gestures are breaking now when building with xcode 16?

Hi! Did you ever solve this in any way? We are facing the same problem.
