Answer 1

You need to provide an API KEY for your application. You can follow the steps in this documentation to create an API_KEY from Google Developer Console. (note: the sample API_KEY in the documentation page will probably throw the error, so dont use it, create your own one)

After you get the API KEY from your developer console, you can paste it in the AppDelegate file.

If you are developing an Objective-C app, do this:

[GMSServices provideAPIKey:@"YOUR_API_KEY"];

If you are developing a Swift app, do this:

GMSServices.provideAPIKey("YOUR_API_KEY");

(replace YOUR_API_KEY with your actual key).
