FlutterFlow Local Device Testing fails on iOS 26 - Debug mode blocked by memory protection

Troubleshooting

FlutterFlow 6.3.32's Local Device Testing crashes on iOS 26 physical devices with "Unable to flip between RX and RW memory protection" error. iOS 26 blocks Debug mode's JIT compilation.

Environment:

- FlutterFlow 6.3.32 (Flutter 3.32.4)

- iOS 26.0.1 on physical device

- Xcode 26.0.1

What works:

- iOS Simulator (Debug mode)

- TestFlight builds (Release mode, after reinstall)

- Manual flutter run --profile via terminal

What doesn't work:

- Local Device Testing on physical iOS 26 devices

Question: Can FlutterFlow add Profile or Release mode option to Local Device Testing? Debug mode is fundamentally incompatible with iOS 26's memory security.

What have you tried so far?

- Clean builds and pod reinstalls

- Updated packages

- Tested via Xcode directly

- Confirmed TestFlight Release builds work

- Verified Profile mode works via flutter run --profile

All approaches confirm Debug mode is blocked by iOS 26, but Release/Profile modes work fine.
