feat: Support --no-codesign argument when building for iOS

[jonasbark]

Description

Due to the still horribly complicated provisioning for iOS apps we are building our flutter apps without code signing, then rebuilding them using fastlanes build_app and the correct team IDs:

        sh("cd ../.. && flutter build ipa --release --no-codesign")
        build_app(
            scheme: "Runner",
            export_method: "app-store",
            export_team_id: "...",
        )

The --no-codesign command is not available in shorebird at this point.

Requirements

• add support for --no-codesign argument when building with shorebird release ios-alpha

Additional Context

We also tried to use the standard shorebird release command, but we also fail at issue #936

We generally pass all commands after -- through to the underlying Flutter, so in this case:

shorebird release ios-alpha -- --no-codesign

(Note the extra -- to delineate when shorebird arguments stop and and flutter arguments start.)
might work.

Thanks - that does work indeed. However, the no-codesign argument does not create an IPA, thus the script fails at the next step. It creates a "Runner.xcarchive" file instead.

Reminds me of #878 in that it's an option flutter supports which changes the artifact output.

I'd love to help, but i'm not entirely sure what you're trying to achieve or how we can best help here. It sounds like you need the --no-codesign option to fit into your build process? We don't actually care about the IPA itself, we could use a different artifact for our processes, but that would be quite a bit of change on our end, so we're unlikely to make that super soon.

Feel free to ping us on discord, happy to discuss there too.

The reason I needed to use the --no-codesign option was different issues in regards to provisioning profiles/certificates. Once I will get past issue #936 I will do a few experiments and will provide the proper context to this issue.

[eseidel]

So a fix we could make would be to not depend on an IPA being generated. Are you still attempting to use Shorebird? We're happy to work with you here, but we've not heard of anyone else with a config like this. :) https://discord.gg/shorebird.

I will investigate further, but I am still blocked by #936

This is fixed by #1267
