Crash on iOS: 'Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:...] prior to use'

[Gintasz]

I'm using 3.2.0 and when I run the app I get:

2020-03-18 21:56:51.171549+0200 Runner[3009:445768] *** Terminating app due to uncaught exception 'GMSServicesException', reason: 'Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:...] prior to use'

Even though I do have the damn GoogleMap.init('IOS_KEY_HERE'); as 1st line in main()

Have you added iOS API key in the AppDelegate?

[Gintasz]

Didn't, because I missed the link instructing to do so in readme. After adding, it works fine.

Okay, I'll update readme, it's important step, it needs to be obvious how to setup all of it.
