iOS 17 Cannot properly build release version

[blk-raffy]

Description

All started by this error: Could not find module 'MapboxMaps' for target 'arm64-apple-ios-simulator'; found: x86_64-apple-ios-simulator

I've found other closed issue but they were old and not currently working.

Context:

I'm using an M1 chip

Troubleshooting

Ok so the problem is (i think) this package does not support Apple Silicon chip. Ok the solutions would be searching for xcode.app > "Get info" > and toggle "Open with Rosetta"

Well, I don't have this toggle so, by opening xcode instead of vscode (I build with vscode yes) and build the project a dialog shows up:

Nice, let's build with Rosetta then!

Hurray, you have a loop.

What I have to do?

Same issue here

@blk-raffy @nicolamazz What version of the Mapbox Maps Flutter Plugin do you use? I have no issues with it working on MBP with M1 Pro chip. @blk-raffy You flutter version is 3.19.0-9.0.pre.206, does it help if you switch back to the stable flutter version?

[blk-raffy]

@evil159 I've switched the version of flutter hoping it was a solved issue. I've switched to the main branch and there is the issue there too. I think it's a mapbox related issue because I have another app with mapbox-gl (old flutter package) and it works fine.

I'm using the lastest version of mapbox

Update, by doing flutter build ios the build works fine

But if I start the emulator I get this:

The problem is xcode or the emulator? (I think xcode only because the builded app won't boot, it's stucked into the splash screen)

Had the exact same symptoms mentioned above on my M1 Pro, resolved it locally by following these steps:

Verifying the project's Podfile:

Previously, I had been using the Mapbox GL Flutter package and had updated my project's Podfile to address a past issue for M1 Macs (https://github.com/mapbox/mapbox-gl-native-ios/issues/487#issuecomment-901146551). I had previously updated my build settings to not target arm64, I reverted this change.

Original Configuration:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
    end
  end
end

Reverted to:

post_install do |installer|
  installer.pods_project.targets.each do |target| 
    flutter_additional_ios_build_settings(target)
  end
end

Removing the Mapbox GL package (https://pub.dev/packages/mapbox_gl):

I was unable to run the simulator with the old Mapbox GL package still installed. Since I'm migrating to this package, I chose to remove it from my project:

• Removed the old Mapbox GL package from my pubspec.yaml.
• Deleted Podfile.lock in the iOS folder.
• Ran flutter clean from the main project directory.
• Ran flutter pub get from the main project directory.
• Ran the project with the iPhone Simulator selected in VSCode.

This resolved the issue for me, I hope this helps!
