Concurrency

These are the most useful proposals for most iOS engineers. Read these documents in this order.

1. [Structured concurrency][5]
2. [Sendable and @Sendable closures][4]
3. [Actors][3]
4. [Async/await][1]

Actors

• [Asynchronous Main Semantics][12]

I couldn't keep track of all the RFCs related to OAuth. So here they are.

OAuth 2.0 RFCs

1. [The OAuth 2.0 Authorization Framework][1]
2. [Proof Key for Code Exchange by OAuth Public Clients][2]
3. [OAuth 2.0 for Native Apps][3]
4. [OAuth 2.0 Device Authorization Grant][4]
5. [OAuth 2.0 Token Exchange][14]

These RFCs underly the OAuth.
