I believe just today Google released a new update to their iOS Analytics frame work (version 3.0). When I follow the instructions and try to run the code, I get:
I had to add both libz.dylib and AdSupport.framework to the build phases to make this go away. Google doesn't include these in their instructions so going to check with them to make sure this is OK then will update this post.
UPDATE: Now you also need to add libsqlite3.0.dylib to get it to work.
