I am also having the exact same problem. I'm actively looking for a solution as well

Okay, I found a possible solution Context: Swift UI project Sonoma & Xcode 15 Project files in document folder macOS project Under project settings -> Signing & Capabilities -> Signing -> Team I had it Set to NONE Under project settings -> Signing & Capabilities -> Signing -> macOS -> Signing Certificate I had it Set to Sign to run locally Solution: Switching project settings -> Signing & Capabilities -> Signing -> Team to any development ID, for me my personal team account. Switching project settings -> Signing & Capabilities -> Signing -> macOS -> Signing Certificate to Development This has worked for me SO FAR, but hopefully it is helpful for anyone that stumbles on this.
