Description

If so there is a working OpenIddict-based sample https://github.com/Ecierge/openiddict-core/tree/apple-cryptokit/sandbox that provides this functionality for iOS and MacCatalyst. It imports Apple CryptoKit and allows generating of RSA keys required for PKCE.

Research direction
The issue references an OpenIddict based sample (https://github.com/Ecierge/openiddict core/tree/apple cryptokit/sandbox) that provides OAuth2 functionality for iOS and MacCatalyst using Apple CryptoKit. To implement OAuth2Manager in Uno, examine the sample to understand the required RSA key generation and PKCE flow. Also review the Microsoft documentation on OAuth2 for Windows apps. Look at the existing authentication framework in the Uno codebase to integrate the new manager. The discussion in the issue may provide further guidance on platform specific considerations.
