I'm having a error after I put in my app a admob. yesterday the app worked fine but today it did not worked anymore .. the error is as follows:
ld: library not found for -lGoogleAdMobAds
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Sometimes you just remove the reference of the library and add reference again.
Apart from adding the Google Mobile Ads SDK and other libraries again from scratch, I would recommend you checking the Library Search Paths. There are instances when you copy or duplicate a target, Xcode decides that it needs to escape any double quotes " with a '\'. Make sure you remove all the \’s - it should look like this -
I was able to duplicate the error, by doing prefixing my path with multiple '\'.
