Converting an non ARC project to ARC error

When I converting my iPhone project to Objective - c ARC I am getting the same error all the time:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can't figure out the architecture type of: /Users/user/Library/Developer/Xcode/DerivedData/TestApp-fktzngidcyimjibgdosyphgbuzpe/Build/Intermediates/TestApp.build/Debug-iphoneos/TestApp.build/Objects-normal/armv7/TestAppCommand /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo failed with exit code 1

Please can someone advice me how can I resolve this?

Make sure that you added the -fno-objc-arc flag to each implementation file (.m file).

And then clean the project (Project menu -> clean) and build again. I have sometimes had to clean and build twice when doing this in class. Seems like a little bug.

Try to use this one

I solved this issue by changing the value of the Valid Architecture found in Project > Build Settings Architectures from the default "armv6 armv7" to "armv7". Hope this helps.

If you are using 3rd party libraries that don't support ARC you should just add this flag to the files in question in your build phases/compile sources (prevents ARC on only those files). This should help you determine if your code is the issue or the library you are using (if that's the case).

-fno-objc-arc
