Resolves: IOS-734
Resolves: IOS-735

🎯 Goal

Use Swift 6 with strict concurrency checking set to complete

📝 Summary

• Set Swift version to 6 with strict concurrency checking complete (including test tools, demo app, mock server)
• Drop Xcode 15 support
• Add Sendable conformances to public types
• Add @sendable to many closure callbacks
• LLC: Controller delegates and completion handlers are @mainactor (removed callbackDelegate)
• UIKit: Nuke was upgraded from 10 to 12 (brings Swift 6 support)
• UIKit: Use @mainactor in delegates

🛠 Implementation

Tried to make it as concise as possible, therefore in some cases there is nonisolated(unsafe), because fixing them properly leads to huge refactoring (too large scope). In many cases this is actually all right.

🧪 Manual Testing Notes

Needs full regression testing round.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

[martinmitrevski]

Looks good ✅ Left few small comments, and let's do a round of tests. Did you test the changes already?

[martinmitrevski]

Why not final, but unchecked Sendable like the others?

[laevandus]

It is because it is subclassed here:
final class CurrentUserPayload: UserPayload, @unchecked Sendable {

[martinmitrevski]

Shouldn't we use the StreamConcurrency.onMain here?

[laevandus]

There is a tiny difference and I did not want to change it (being extra careful). StreamConcurrency.onMain has DispatchQueue.main.sync here because it supports returning a value (needed in some cases).

[martinmitrevski]

Why do we change this?

[laevandus]

Since we changed controller delegates to be @mainactor (delegates ran on the callbackQueue which is main), then this has a side-effect where controller can't conform to EventsControllerDelegate easily since delegate conformance would then require main actor, but controller types are not.

@MainActor public protocol EventsControllerDelegate: AnyObject {

Option 1 (current): Add @mainactor toEventsControllerDelegate and change the code where we use it in controllers
Option 2: Do not add @mainactor to EventsControllerDelegate, but if @mainactor view model or etc implements it, it as to use nonisolated for the delegate method and dispatch the call to main thread.

[laevandus]

This was discussed internally and we decided to use the subscribe method instead for controllers.

[martinmitrevski]

Interesting, why do we need it?

[laevandus]

Does not like setting merge policy.

Sources/StreamChat/Database/DatabaseContainer.swift:25:31 Reference to var 'NSMergeByPropertyObjectTrumpMergePolicy' is not concurrency-safe because it involves shared mutable state

[martinmitrevski]

Why do we change this?

[laevandus]

It is a deprecated in Swift 6: reference and Xcode shows a warning here since we bumped Swift version.

[martinmitrevski]

@laevandus actually it doesn't build for me on Xcode 16.2.

Why do we need this? Can't we make StreamAudioPlayer MainActor?
