Using the StravaApp for Authentication on iOS with SwiftUI

[Aendu21]

In my iOS App I implemented the authentication flow according to the Strava Documentation.

1. Checking if the StravaApp is installed, if yes, I'm using <UIApplication.shared.open> to redirect to the StravaApp.
2. If the StravaApp is not installed I'm using <ASWebAuthenticationSession>

Everthing works OK, except in the case when the StravaApp is used for authentication.

After the user has authorised the connection to Strava inside the StravaApp, it returns to my app but the callback to my AppDelegate never happens. So I don’t get the url with the authorization code. My App uses SwiftUI. I'm injecting the AppDelegate in in my App scene:

@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

AppDelegate implementation:

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        print("url returned from Strava App: \(url)")
        return true
    }
}

Thanks for your help
