After reprogramming my view, which didn't work, I was able to simulate it in canvas. There was some changes in the SwiftUI - methods like in toggle and Picker view (by the way, this wasn't described in the developer documentation). The problem is, that now I needed to implement an .on tap gesture{} to my toggle? With the picker they changed the default picker style. But still, with a cleaned up code my cpu usage still runs crazy and canvas continuously load data to my ram, till Xcode stuck and I need to restart my pc. Swift-frontend and kernel task uses of all capacities of my Mac Book Pro 2020 since updating Xcode to Version 13 and updating macOS to Monterey.
Why Xcode was running canvas before so smooth?
Are you already discovered a problem and will solve this soon?
I think also other developer run in to the same problem.
