Hi All,  
I’m trying to implement Auth0 in my iOS Swift app.  
I’m following the steps at: [GitHub - auth0/Lock.swift: A Swift & iOS framework to authenticate using Auth0 and with a Native Look & Feel · GitHub](https://github.com/auth0/Lock.swift) and [Lock.swift - Auth0 Docs](https://auth0.com/docs/libraries/lock-ios/v2) but running into an error when trying to get the login window to present:

> canOpenURL: failed for URL:  
> “org-appextension-feature-password-management://”
> 
> - error: “This app is not allowed to query for scheme  
> org-appextension-feature-password-management”

Any ideas where I am going wrong?  
Thanks  
Mathew

I’m having the exact same issue, were you able to resolve this in the end?

This is normal and expected behavior when there is no app that can open a custom URL. In this case when the 1Password app is not installed. Unfortunately, the message can be a little confusing but it is coming from iOS itself and is nothing to be concerned about.

A note regarding this has be added to the Lock.swift README.
