Use of unresolved identifier 'connections'; did you mean 'Connections' in Auth0?

I'm working on Auth0 Lock integration, i'm getting error Use of unresolved identifier 'connections'; did you mean 'Connections'?.

.withConnections {_ in
  connections.database(name: "Username-Password-Authentication", requiresUsername: true)
}

I changed code to

Connections.database(name: "Username-Password-Authentication", requiresUsername: true)

Now I'm getting error Instance member 'database' cannot be used on type 'Connections'

When I changed code to

Connections().database(name: "Username-Password-Authentication", requiresUsername: true)

Getting error 'Connections' cannot be constructed because it has no accessible initializers

I changed code to

$0.database(name: "Username-Password-Authentication", requiresUsername: true)

Getting Anonymous closure arguments cannot be used inside a closure that has explicit arguments

            $0.scope = "openid profile"
        }

            // Let's save our credentials.accessToken value
        }
        .withConnections {_ in
            connections.database(name: "Username-Password-Authentication", requiresUsername: true)
        }
        .withStyle {
            $0.title = "Company LLC"
            $0.logo = LazyImage(name: "123.png")
            $0.primaryColor = UIColor(red: 0.6784, green: 0.5412, blue: 0.7333, alpha: 1.0)
        }
        .present(from: self)

Solution

It seems the Auth0 documentation is erroneous here. If you look at the Lock.swift source file you see that a ConnectionBuildable is passed as argument. You need to use this to build your connections.

Try this:

.withConnections { connections in
    connections.database(name: "Username-Password-Authentication", requiresUsername: true)
}

or the same thing using anonymous closure arguments:

.withConnections {
    $0.database(name: "Username-Password-Authentication", requiresUsername: true)
}
