I’m working on integrating authentication with our auth0 tenant in a iOS application using the auth0.swift package. We are running into an issue when running the app in the iOS simulator (we have not been able to reproduce the issue on a physical device) both in our app and also the iOS sample app provided by auth0.
After setup (using our custom auth0 domain) as stated here in the auth0-ios-swift-sample repo on GitHub. The initial login attempt succeeds without any issues and i’m taken to the ProfileView and expected details are shown.
After stopping the app in xcode and running it again the below error messages are shown when the login process is triggered.
Updating the auth0 plist file and switching the the default domain stated on the auth0 application can sometimes solve the issue for one cycle. In subsequent attempts the sheet for Universal login will only show “Safari can’t open the page because the network connection was lost”.
Applying .useEphemeralSession() does not make a difference, behaviour is the same.
- xcode: 16.3
- macOS: Version 15.4.1 (24E263)
- Apple Macbook Pro M4
- auth0.swift 2.11.0
Any ideas what could be causing this issue or how to solve it?
Thanks!
