Framework was built without full bitcode - Framework bitcode already enabled

if you do below commands

• Enable Bitcode' set to 'YES' Adding
• Flags' Adding 'BITCODE_GENERATION_MODE' with the value 'bitcode' set skip install to yes

they will not work until

• flutter clean
• flutter build ios

so that after you change build settings you need to run flutter build

Bitcode is an abstract encoding of an app that can be used to re-compile it in different ways, given a set of instructions. You can confirm whether your binary is bitcode-compatible by running :

otool -l (my .o or .a file) | grep __LLVM.

When you build normally, Xcode adds the build flag -fembed-bitcode-marker to any clang invocation.

To Add -fembed-bitcode: select project Build Settings -> Other C flags, set Debug to -fembed-bitcode-marker and Release to -fembed-bitcode this will build your lib with bitcode.

BITCODE_GENERATION_MODE

If you set BITCODE_GENERATION_MODE=bitcode on your User-defined Setting, even during the build phase, the files will be compiled using the flag -fembed-bitcode.

And, if you set BITCODE_GENERATION_MODE=marker, the files will be compiled using the flag -fembed-bitcode-marker, independent of the action phase.

So, if you want to enable the bitcode to every action (build and archive), the better way to do so is using the BITCODE_GENERATION_MODE setting you can do so either manual or by script.

Manual

On Build Settings, click on the + sign at the top to add a user-defined build setting with the name BITCODE_GENERATION_MODE, and set Debug to marker, Release to bitcode.

Edit schema as Release Then link the library.a file and get the build path get the library form Release folder

Script

xcodebuild BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode" -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

Try to set Skip Install to YES and Enable Bitcode to Yes in framework build settings.

In my case, I have a unity project, and I want to export it to the ios library to integrate with another project. So I need to archive it -> Xcode show "library was built without full bitcode"

My solution for this case is:

• Target -> Framework need archive -> Build setting -> Enable bitcode = NO
