feat(ios): universal multiplatform build, adaptive split navigation, keyboard shortcuts & haptics - #283
Conversation
…hortcuts and haptics
📝 WalkthroughWalkthroughThe companion app adds cross-platform support for macOS and Mac Catalyst, split navigation for regular-width layouts, persisted UI zoom, platform feedback helpers, enhanced chat actions, and conditional pairing-scanner support. ChangesCompanion workspace
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change expands the app to desktop-compatible destinations, but scanner code may still use unavailable APIs or request camera permission on the desktop target, potentially causing build or runtime failures. Approval feedback can also report success before a request succeeds, and hydrated chats may not auto-select. These issues should be addressed or explicitly accepted before merge.

XcodeGen project.yml supportedDestinations macOS platform iOS SUPPORTS_MACCATALYST semantics
💡 Result:
In XcodeGen, the supportedDestinations key is used to define multi-platform support for a target, effectively replacing the older single-platform definition [1]. When using this feature, you should set the target platform to auto, which is specifically designed to work with supportedDestinations [2][3][4]. Regarding Mac Catalyst: 1. Supported Destinations: You can include macCatalyst in your supportedDestinations list [2][5]. 2. Implicit Requirements: XcodeGen automatically adds iOS to the supportedDestinations list if it contains only macCatalyst but lacks iOS, ensuring compatibility with the underlying requirements for Mac Catalyst targets [6]. 3. Semantic Settings: While supportedDestinations handles the structural platform support, specific Mac Catalyst build settings like SUPPORTS_MACCATALYST and DERIVE_MACCATALYST_PRODUCT_BUNDLE_IDENTIFIER are not automatically generated by the destination key alone [7]. You must explicitly define these in the target's settings block if they are required for your project [7]. Example configuration: targets: MyApp: type: application platform: auto supportedDestinations: [iOS, macCatalyst] settings: base: SUPPORTS_MACCATALYST: YES DERIVE_MACCATALYST_PRODUCT_BUNDLE_IDENTIFIER: YES

Success feedback plays for a refusal, and before the request settles.
ForEach(card.options, ...) at line 584 covers every option, including the "Deny" option that line 595 already identifies through Self.isRefusal(option). Tapping "Deny" therefore plays the action-success sound and the success haptic. The feedback also fires before session.answer returns, so it plays even when the call fails. Line 608-609 has the same pre-request ordering for "Always allow this tool". Gate the feedback on the option and move it after the await.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Auto-selection can never run after the roster hydrates.
onAppear runs before the session hydrates, so session.state.chatSummaries and pendingApprovals are both empty at that moment and autoSelectFirstChat() selects nothing. After that, re-selection is observed only on pendingApprovals.count. A user with chats but no pending approval therefore sees the "Select a Conversation" placeholder until they tap a row. Also observe the roster count.
🐛 Proposed fix
.onChange(of: session.state.pendingApprovals.count) { _, _ in
if selectedChat == nil {
autoSelectFirstChat()
}
}
+ .onChange(of: session.state.chatSummaries.count) { _, _ in

Apple AVCaptureDevice requestAccess(for:) Mac Catalyst camera permission behavior targetEnvironment(macCatalyst)
💡 Result:
In Mac Catalyst, AVCaptureDevice.requestAccess(for:) behaves similarly to its iOS counterpart but requires specific macOS-compatible configuration to function correctly [1][2][3]. To successfully request and obtain camera permission in a Mac Catalyst app, you must ensure the following: 1. Info.plist Requirement: You must include the NSCameraUsageDescription key in your Info.plist file [4][1][2]. This string provides the explanation displayed to the user when the system prompts for camera access [1][5]. Failure to include this key will cause the system to terminate your app when it attempts to access the camera [1]. 2. Entitlements: For Mac Catalyst apps, you must enable the Camera entitlement in the Signing & Capabilities section of your project target [1][3]. This is a requirement specific to macOS that is not needed for pure iOS apps [1][3]. 3. Authorization Flow: Before initiating capture, you should check the authorization status using AVCaptureDevice.authorizationStatus(for:) [1][2][3]. If the status is.notDetermined, call AVCaptureDevice.requestAccess(for:completionHandler:) to trigger the system-provided permission alert [1][2][3]. The completion handler will be executed once the user responds [2]. While earlier versions of Mac Catalyst had limitations regarding AVFoundation capture classes, modern versions support them [6]. If you encounter issues with device discovery, ensure your code is compatible with the Mac environment (e.g., handling specific device types or, if necessary, utilizing workarounds like UIImagePickerController for simpler capture needs) [7][6][8]. Always test on a physical Mac, as camera access behavior and availability may differ significantly from the simulator [6].

Do not request camera permission on Mac Catalyst.
The shared .task and .onChange modifiers still run on Catalyst. When authorization is .notDetermined, they call AVCaptureDevice.requestAccess(for: .video). Guard both modifiers with #if os(iOS) && !targetEnvironment(macCatalyst).

In `@ios/App/PairingScanner.swift` at line 81, Guard the shared .task and
.onChange camera-authorization handlers in PairingScanner with `#if` os(iOS) &&
!targetEnvironment(macCatalyst), so AVCaptureDevice.requestAccess(for: .video)
is never invoked on Mac Catalyst while preserving the existing iOS behavior.

Thanks for the contribution — the focused haptics portion of this work has now landed on main through #561. We intentionally kept the iOS app iPhone-native and left out the bundled Catalyst, split-navigation, and global zoom changes, so I’m closing this larger PR in favor of the smaller merged implementation. |
