App crashes on physical device but works in simulator

-- -- 922

App works in iPhone simulator from Visual Studio on mac. App also runs on local physical device from Visual Studio for pc (after using this hack https://gist.github.com/mattjohnsonpint/37d3ac06a563c41618fc933bf7282d66). However app crashes on physical device at start-up when deployed via Test Flight. Logs from both the physical device and test flight attached.

Any help would be appreciated.

Thanks

From the log, I can see the app crashes on your iOS 16.6.1 device. And there is an abort due to an exception:

"exception" : {"codes":"0x0000000000000000, 0x0000000000000000","rawCodes":[0,0],"type":"EXC_CRASH","signal":"SIGABRT"}, "termination" : {"flags":0,"code":6,"namespace":"SIGNAL","indicator":"Abort trap: 6","byProc":"MyApp","byPid":506},

App also runs on local physical device from Visual Studio for pc (after using this hack

You are using Hot restart, right? Please try to connect your device with MAC, then Pair to Mac and select the remote device.

For the TestFlight issue, you could try to add UseInterpreter in your csproj file.

<PropertyGroup> <UseInterpreter>true</UseInterpreter> </PropertyGroup>

And may I ask how you publish the app to AppstoreConnect? via VS for Mac or pair to mac with PC? What's the MAUI version and what's the VS version?

When you run the app on your physical device by selecting the "iOS Remote Devices" tab (behind "iOS Simulators"), does the app crash?

Hi, So there is an issue in MAUI (there is an entry on MAUI github for it) that if a static resource is not declared but is used then it does not given error at design time or in debug mode on both iPhone simulator or on physical device. However in release from TestFlight it crashes app. Best way seems to be to use a third party error logger to quickly catch such errors at runtime in release. These are now resolved. Thanks for all the help.

Hello,

As -- -- said, your issue has been resolved

"If a static resource is not declared but is used then it does not given error at design time or in debug mode on both iPhone simulator or on physical device. However, in release from TestFlight it crashes app. Best way seems to be to use a third party error logger to quickly catch such errors at runtime in release."

(Refer to this issue- Missing StaticResource should throw exception also in Debug #15602)
