If Xcode complains when linking, e.g. Library not found for -lPods, it doesn‘t detect the implicit dependencies:
1.Go to Product > Edit Scheme
2.Click on Build
3.Add the
Pods
static library, and make sure it‘s at the top of the list
4.Clean and build again
If that doesn‘t work, verify that the source for the spec you are trying to include has been pulled from 5.github. Do this by looking in /Pods/. If it is empty (it should not be), verify that the ~/.cocoapods/master//.podspec has the correct git hub url in it.
6.If still doesn‘t work, check your XCode build locations settings. Go to Preferences -> Locations -> Derived Data -> Advanced and set build location to "Relative to Workspace".
