Hi there
I've recently had my upload rejected in Xcode Organizer as a result of one of the frameworks we use containing bitcode.
Error: [ContentDelivery.Uploader.XXXXXXXXXX] Validation failed (409) Invalid Executable. The executable 'Sam.app/Frameworks/Foo.framework/Foo' contains bitcode.
Is there an accurate way to determine whether an .xcframework contains bitcode ahead of time without using Xcode Organiser?
My current methodology is below, please can I get some confirmation that this is accurate, or suggest a more efficient approach?
I have concerns about my approach and whether it throws false positives for empty bitcode markers.
1. get original framework size
2. run xcrun bitcode_strip -r framework_path -o temp
3. get new framework size
4. if new size is smaller than original, then it contains bitcode
Thanks for the help, Sam
The bitcode_strip man page explains that bitcode is stored in the __LLVM segment. You can check for its presence using otool with the -l option.
ps If you search the ’net for "__LLVM", you’ll find various folks explaining how this works in general. I’m focusing on your specific question here because… well… bitcode is no longer relevant to the Apple ecosystem.
Share and Enjoy
