Resolves: IOS-1952

🎯 Goal

Use generated structs for ChannelCapabilities, VotingVisibility and PushPreferenceLevel

📝 Summary

  • Implemented enum>struct generation without nested types in the chat repo (CHA-4706)
  • This PR replaces handcrafted structs with generated ones
  • Deprecate old calling related capabilities not returned by backend (skipped CHANGELOG entry because there should be no-one using it)

🛠 Implementation

Summary by CodeRabbit

  • New Features

    • Preserved unrecognized channel capabilities when channels are received or saved and loaded.
    • Added convenient string-literal support for channel capabilities and push preference levels.
  • Deprecations

    • Deprecated calling-related channel capability constants and properties.
    • Removed the public voting visibility type.
  • Bug Fixes

    • Improved poll visibility and push preference handling.
    • Preserved device provider and live-location values without unintended fallback or conversion.

📝 Walkthrough

Walkthrough

The OpenAPI generator now emits typed RawRepresentable structs for capabilities, poll visibility, and push preferences. Stream Chat preserves unknown capabilities and forwards typed request values directly. Deprecated call-capability APIs remain available.

Changes

Typed model migration

Layer / File(s) Summary
Generated model contracts
Scripts/openapi_generate.sh, Sources/StreamChat/Controllers/PollController/PollController.swift, Sources/StreamChat/Models/ChannelCapability+Extensions.swift, Sources/StreamChat/Models/PushPreferences/PushPreferenceLevel.swift
The generator emits and exposes typed structs, renames generated types, removes obsolete declarations, and preserves compatibility constants and string-literal initialization.
Capability preservation and compatibility
Sources/StreamChat/APIClient/Endpoints/Payloads/ChannelDetailPayload+Extensions.swift, Sources/StreamChat/Models/Payload+asModel/ChannelPayload+asModel.swift, Sources/StreamChat/Database/DTOs/ChannelDTO.swift, Sources/StreamChat/Models/Channel.swift, Tests/StreamChatTests/Database/DTOs/ChannelDTO_Tests.swift, Tests/StreamChatTests/Models/ChatChannel_Tests.swift
Channel capability mapping retains unknown raw values. Call capability properties and constants are deprecated. Tests cover persistence and capability behavior.
Typed poll and push request integration
Sources/StreamChat/Controllers/ChannelController/ChannelController.swift, Sources/StreamChat/Controllers/CurrentUserController/CurrentUserController.swift, Sources/StreamChat/Repositories/PollsRepository.swift
Poll visibility and push-preference values pass directly into typed request inputs without raw-value conversions.
Direct request value forwarding
Sources/StreamChat/Workers/CurrentUserUpdater.swift, Sources/StreamChat/Workers/MessageUpdater.swift, Tests/StreamChatTests/Workers/CurrentUserUpdater_Tests.swift
Device creation no longer falls back to .unknown, and live-location coordinates no longer convert explicitly to Float. Tests use the direct provider conversion.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 1b45a

This change replaces handcrafted API models with generated capability and preference models while retaining deprecated capability APIs and updating live-location handling. If deprecated APIs were publicly shipped or unusual payload and coordinate values occur, regressions could go undetected or values could lose precision; the PR is mergeable with explicit owner awareness and follow-up coverage.

Add direct payload conversion coverage.

Add a ChannelPayload.asModel test with a known capability and an unknown raw value. The DTO persistence test does not cover this live conversion path. Assert that both values remain in ChatChannel.ownCapabilities.

As per coding guidelines, “Agents should prioritize backwards compatibility, API stability, and high test coverage when changing code.”

Add a precision-preserving request test.

Add a MessageUpdater.updateLiveLocation test with coordinates that cannot be represented exactly as Float. Assert that UpdateLiveLocationRequest receives the original values. Use waitFor from StreamChatTestTools for the async completion.

As per coding guidelines, “Agents should prioritize backwards compatibility, API stability, and high test coverage when changing code,” and tests must use waitFor instead of manual expectations.
