Exception:Google Maps SDK for iOS must be initialized via [GMSServices provideAPIKey:…] prior to use

Question

I am trying to implement Google Maps SDK into my project using Swift 2.0. I follow this but when running this, my app is getting the following error:

Answer 1

XCODE 12.0.1, Swift 5

I was applying constraints to Google Map View by initialising GMSMapView like this:-

private var googleMapsView : GMSMapView = {
    let mainView = GMSMapView()
    mainView.translatesAutoresizingMaskIntoConstraints = false
    mainView.isMyLocationEnabled = true
    return mainView
}()

& I was getting this same error, so I tried this making it a lazy property:-

lazy private var googleMapsView : GMSMapView = {
    let mainView = GMSMapView()
    mainView.translatesAutoresizingMaskIntoConstraints = false
    mainView.isMyLocationEnabled = true
    return mainView
}()

& voila! It worked like a charm.
