fix: "Encountered error while creating the IPA" may only be a warning

[TonyD-TuftAndPaw]

App ID: com.tuftandpaw.app.staging

Description

flutter build skims over the message "Encountered error while creating the IPA", where shorebird release halts.

Steps To Reproduce

(Sorry, maybe later?)

Expected Behavior

shorebird release should not halt on any warnings that flutter build doesn't halt on.

Additional Context

Logs attached for a successful and unsuccessful run, with the only material difference being the use of shorebird release instead of flutter build.

Hmm, I'm struggling to find a real error in that log. 🤔 @bryanoltman might know.

It does appear to only be a warning https://github.com/shorebirdtech/flutter/blob/shorebird/dev/packages/flutter_tools/lib/src/commands/build_ios.dart#L518-L532

having the same problem

Bryan has been working on adding tooling to help surface common errors from logs. Although I'm still not sure what the error is in these logs. Most often errors building for iOS are signing errors, so another thing to try might be shorebird release ios --no-codesign (not as a final solution, just to see if it works while disabling XCode signing).
