Google Maps GMSPanoramaView api blocked - ios

Question

I'm getting this error:
This application has been blocked by the Google Maps API. This might be because of an incorrectly registered key.
When I try to set google maps panorama street view. If I display a regular map view, it works so seems like the key is registered properly.
I followed the directions for a panorama view exactly as per google docs:
import UIKit
import GoogleMaps
class ViewController: UIViewController, GMSMapViewDelegate {
override func loadView() {
let panoView = GMSPanoramaView(frame: .zero)
self.view = panoView
panoView.moveNearCoordinate(CLLocationCoordinate2D(latitude: -33.732, longitude: 150.312))
}
}
Any ideas?

Answer 1

For me, the solution was that I needed to link my project in Google Cloud Platform to a billing account.
Once I did that the street view started working correctly.
The standard Google map worked fine without a billing account, which confused me initially.

You need to configure the delegate for this object. Something like:
import UIKit
import GoogleMaps
class ViewController: UIViewController, GMSMapViewDelegate {
override func loadView() {
let panoView = GMSPanoramaView(frame: .zero)
panoView.delegate = self
self.view = panoView
panoView.moveNearCoordinate(CLLocationCoordinate2D(latitude: -33.732, longitude: 150.312))
}
}
extension ViewController: GMSPanoramaViewDelegate {
func panoramaView(_ view: GMSPanoramaView, error: Error, onMoveNearCoordinate coordinate: CLLocationCoordinate2D) {
print("error: \(error.localizedDescription)")
}
}
