AWS amplify add auth: how to add a redirect signin URI after executing the amplify cli

Question

Context: I was following a AWS tutorial to create iOS application using Amplify. One of the steps was to use 'amplify add auth' and specify the 'redirect signing URI'. For some reason the CLI didn't prompt me for the URL. 'amplify update auth' does not provide an option to specify the redirect URL.

Question: How can I add redirect URL to the project, after executing the 'amplify add auth' command?

Answer 1

I don't know what problem you are having, but you can use

amplify update auth

If you try:

amplify add auth

It will give you an error:

Auth has already been added to this project. To update run amplify update auth.

Use amplify update auth, you will be asked for the URI.
