You need to set the  linker search paths  of the project  for both Debug and Release builds    If this library was in  say  a sibling directory to the project then you can set it like this     PROJECT DIR     GoogleAnalytics lib   you want to avoid using an absolute path  instead keep the library directory relative to the project

If you are using Pods to include the GoogleAnalytics iOS SDK into your project  it s worth noting that since the 3 0 release your Other Linker Flags needs to include -lGoogleAnalyticsServices not the old -lGoogleAnalytics

The problem might be the following  SVN ignores  a files because of its global config  which means someone didn t commit the libGoogleAnalytics a to SVN  because it didn t show up in SVN  So now you try to check out the project from SVN which now misses the libGoogleAnalytics a  since it was ignored and was not committed   Of course the build fails   You might want to change the global ignore config from SVN to stop ignoring   a files   Or just add the one missing libGoogleAnalytics a file manually to your SVN working copy instead of changing SVNs global ignore config   Then re-add libGoogleAnalytics a to your XCode project and commit it to SVN

All in all  the Xcode cannot find the position of library header framework  then you tell Xcode where they are   set the path that Xcode use to find library header framework in Build Settings --  Library Header Framework Search Paths   Say  now it cannot find -lGoogleAnalytics  so you add the directory where -lGoogleAnalytics is to the Library Search Paths
