Summary

This PR updates the iOS bindings from libxmtp 1.6.1-rc2 to 4.7.0-dev.f5bec47. The changes are primarily auto-generated Swift bindings from the Rust uniffi toolchain.

Review Findings

✅ Looks Good

Package.swift & XMTP.podspec:

• Binary URL correctly points to swift-bindings-1.7.0-dev.f5bec47 release
• SHA256 checksum is properly updated (29d7aef...)
• Version bump is consistent across both files

New Features (from binding changes):

• streamMessageDeletions() - Callback for disappearing messages worker deletions
• insertedAtNs() - New timestamp accessor on FfiDecodedMessage
• FfiMessageDeletionCallback protocol - Proper callback interface for deletion notifications

Code Quality:

• Auto-generated code follows consistent uniffi patterns
• Proper memory management with uniffiClonePointer() and deinit
• Thread-safety maintained with @unchecked Sendable and NSLock

⚠️ Minor Observations

1. New dynamic target file: Sources/XMTPiOSDynamic/Libxmtp/xmtpv3.swift is added (15,533 lines) but I don't see a corresponding target definition in Package.swift. Verify this is intentional - may need to be added to the package manifest if it should be a separate dynamic library target.

2. Dev version: This is a -dev prerelease version. Ensure this is expected for the current development cycle.

3. Large line changes: 886 additions to the static bindings indicate significant API additions in libxmtp. Consider documenting the new capabilities in the SDK's public API if they're exposed to users.

🔒 Security

• No hardcoded secrets or credentials
• URLs point to official xmtp GitHub releases
• Checksums properly validate binary integrity

Recommendation

Approve - This is a standard automated libxmtp update with proper checksums and consistent versioning. The new APIs (streamMessageDeletions, insertedAtNs) follow existing patterns and are well-structured.

Consider:

• Verifying if the dynamic target needs Package.swift configuration
• Adding integration tests for the new streamMessageDeletions functionality if it's a key feature

Update Swift bindings to libxmtp 4.7.0-dev.f5bec47 and add FfiConversationsProtocol.streamMessageDeletions with message insertion timestamp support

Bumps the FFI artifact and CocoaPods version to 4.7.0-dev.f5bec47, adds a deletion stream callback via FfiConversationsProtocol.streamMessageDeletions, introduces insertion timestamp access on decoded messages and messages, and extends FFI types/enums to carry intents, actions, and sort options.

📍Where to Start

Start with the new stream API in FfiConversationsProtocol.streamMessageDeletions in xmtpv3.swift; then review the added FFI callback interface and converters nearby.
