Xcode 8.3.2 Clang Error

Question

I am trying to update one of my project, when I opened it I performed validated settings, but when I try to build it I just face with this error :

Apple Mach-O Linker Error Group : clang: error: linker command failed with exit code 1 (use -v to see invocation)

with no more infos and I am not using cocoapods or any external frameworks. I just searched everywhere and did any possible solution such as :

• Clean and run
• Searched for duplicate files
• Check imported header files
• Delete xxxTest
• Checked Build Active architecture
• Validated Settings
• Checked missing frameworks
• Restart mac
• Changed iOS deployment target
• Disabled bitcode

and etc...

Is there anything to solve this issue ?!

Answer 1

Right-click the error in the the Issue Navigator. Choose "Reveal in Log" or "Reveal in Project Navigator "and see the actual error message.

Answer 2

-Try this 1.Xcode -> Preferences -> Location -> click on derived data path and clear all derived data. 2."Build Phases" -> "Compile Sources" and look for duplicate of classes. 3.Or check if you have "*.m" files in your #import

Answer 3

I got this error when I forget to update my submodules (Carthage in my case). After I update my submodules I didn't get the error.
