OIDAuthState.authState fails to show login browser on iOS 13

HI Team,

I am working on iOS 13 support for my framework. My solution environment is following:

• AppAuth 1.2.0
• Xcode 11 GM seed

I have tested in 1.1.0 also.

While launching web browser from my component, the alert is getting disappeared and getting below error:

Printing description of authorizationError:

Error Domain=org.openid.appauth.general Code=-3 "(null)" UserInfo={NSUnderlyingError=0x600002816b50 {Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=2 "Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start." UserInfo={NSDebugDescription=Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start.}}}

Please help me which verison to take. I saw one more issue was raised like this but it was in iOS 13 beta branch.

Reproduce the failure on iOS 13 with AppAuth 1.2.0 and 1.1.0, starting from OIDAuthState.authState and the reported ASWebAuthenticationSession error. Trace the browser-launch path to identify the missing presentation context; done means the login browser appears without the Code -3 error.
