iOS build failed with `ld: bitcode bundle could not be generated`

Question

I have following error when building iOS with CodeMagic.

    Running Xcode build...

Encountered error while archiving for device.

To solve this issue, I changed ENABLE_BITCODE value to YES in project.pbxproj but the same error occurs.

97C147071CF9000F007C117D /* Release */ = {
        isa = XCBuildConfiguration;
        baseConfigurationReference = 7AFA3C8E1D35SGSDC0083082E /* Release.xcconfig */;
        buildSettings = {
            ASSETCATALOG_COMPILER_APPICON_NAME = AppIcon;
            CLANG_ENABLE_MODULES = YES;
            CURRENT_PROJECT_VERSION = 4;
            DEVELOPMENT_TEAM = 56KC6SGDDR;
            ENABLE_BITCODE = YES;
            INFOPLIST_FILE = Runner/Info.plist;
            LD_RUNPATH_SEARCH_PATHS = (
                "$(inherited)",
                "@executable_path/Frameworks",
            );
            PRODUCT_BUNDLE_IDENTIFIER = com.aaa.bbbMarket;
            PRODUCT_NAME = "$(TARGET_NAME)";
            SWIFT_OBJC_BRIDGING_HEADER = "Runner/Runner-Bridging-Header.h";
            SWIFT_VERSION = 5.0;
            VERSIONING_SYSTEM = "apple-generic";
        };
        name = Release;
    };

And my CodeMagic setting for building iOS is below. my settings in CodeMagic

Our app has already been first built with xcode and updated to the apple store, and we are setting up additional CI/CD now.

How do I solve this? Any help will be highly appreciated. Thanks.

Solution 1

I had a similar problem. My solution was to goto Xcode-Product-Scheme-edit scheme- make sure that the archive schemas build configuration is set to Release. Mine was for some reason set to debug.

Solution 2

I think the solution is opposite you need to disable bitcode because Flutter doesn't use it. You can do it by editing your Podfile to something like this:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |build_configuration|
      build_configuration.build_settings['ENABLE_BITCODE] = 'NO'
    end
  end
end
