I am having a serious linker problem on one of my iOS apps (See previous post for details)
linker command failed with exit code 1 (use -v to see invocation)
Click your project in the Project Navigator. Click the Build Settings tab. Find the Linking section. Under that, add -v to “Other Linker Flags”.
-v
You may need to clean your project or the build folder and rebuild to see the result in the build log.
