Firebase (Phone Auth) Getting iOS error: register custom URL scheme

Question

My flutter app uses Firebase Auth (Phone). I keep seeing the error: 'Please register custom URL scheme 'com.googleusercontent.apps.602546125958-5lk04ghhdfj5xxxxxxxx' .

I have added the URL schema to the info.plist as follows, but I'm getting the same error.

Answer 2

There is a Firebase documentation for iOS phone verification setup:

To enable the Firebase SDK to use reCAPTCHA verification:

Add custom URL schemes to your Xcode project:

1. Open your project configuration: double-click the project name in the left tree view. Select your app from the TARGETS section, then select the Info tab, and expand the URL Types section.
2. Click the + button, and add a URL scheme for your reversed client ID. To find this value, open the GoogleService-Info.plist configuration file, and look for the REVERSED_CLIENT_ID key. Copy the value of that key, and paste it into the URL Schemes box on the configuration page. Leave the other fields blank. When completed, your config should look something similar to the following (but with your application-specific values):

https://firebase.google.com/docs/auth/ios/phone-auth?authuser=0

Works for Flutter too.

Answer 3

I had the same problem. Try with the following setting.

Answer 4

My issue was I had copied the GoogleService-info.plist into the wrong directory. There is a top level folder named after your app, and a folder with the same name, inside that one. So like, MyApp/MyApp , it needs to be inside that second, inner folder.

Answer 5

Add the reverse client id in the url launcher.

Reverse client id is located in googleservies.infolist xcode and copy the url and paste the url in url launcher by add the link

Answer 6

You need to register custom URL scheme in the app's Info.plist file.

Add this line in your info.plist

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleIdentifier</key>
        <string></string>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>enter your custom URL scheme here</string>
        </array>
    </dict>
</array>
