I have the same problem. I was using SFAuthenticationSession and updated to ASWebAuthenticationSession, but still the same issue. What I've found: M1 Max + M1 Pro Mac + Xcode 16 + iOS 18 Simulator: App freezes M1 Max + M1 Pro Mac + Xcode 16 + iOS 17 Simulator: no issue Intel Mac + Xcode 16 + iOS 18 Simulator: no issue I will start testing it with the Xcode 16.1 beta
