apple mach-o linker error linker command failed with exit code 1 (use -v to see invocation)

Question

2I am working with Objective C with core data, I got an error:

Apple Mach-O Linker Error, Linker command failed with exit code 1 (use -v to see invocation)

Solution 1

You need open detail description.

Solution 2

Check if you have imported a .m file instead if .h somewhere in your project.

Another thing to look for is the import of a header file twice.

If the above two don't work Select your project -> Build Phases -> Link Binary with Libraries. Go through the list and see if a framework is added more than once.

In my case there are duplicate files. Thanks

If you're using react-native and seeing duplicate symbols, you may have added a library twice, once manually and once with the react-native link command.
