I made an app for iOS and before publication I have to make view, where I list all used 3rd party libraries licenses. Unfortunately, I cannot find license for GoogleSignIn SDK for iOS. This package is made by Google, but I can't find any informations about license of even license file in installed pod.
On it's pod www site field "License" is filled with value "Custom", but after clicking it I'm redirected to implementation tutorial. Pod description also says to check this link for "integration instructions, documentation, support information, and terms of service." but I don't see any informations about license. What should I do with this package? Should I list it in licenses view without any license details?
