This issue also occurs on the MacBook Air M1 (16/512). Previewing SwiftUI canvas (Xcode 15.0) causes the processor temperature to continuously rise to 70 degrees Celsius and rapidly depletes the battery. Even when the application is closed (not Force Closed), the MacBook remains hot (the Activity Monitor shows that 40% of the CPU resources are still running the Simulator). The only way to cool down the MacBook is by Force Closed both Xcode and the Simulator.
