feat: grant WKWebView camera permission for liveness challenge - #224
Merged
Conversation
Implement WKUIDelegate.requestMediaCapturePermissionFor to grant camera capture so the camera-based liveness challenge's getUserMedia call can start; WKWebView auto-denies otherwise. Camera-only — the challenge uses video with audio:false, and denying microphone avoids requiring the host app to declare NSMicrophoneUsageDescription. Add NSCameraUsageDescription to the example app Info.plist and bump the podspec to 3.1.0. ENG-5947, ENG-5978
- Log the capture-permission decision via Log.debug, matching the other delegate methods in this file. - Add NSCameraUsageDescription to the example targets that use a generated Info.plist and so didn't inherit it from Shared/Info.plist: SwiftUI-Example (its partial Info.plist) and Passive-Example (INFOPLIST_KEY build setting, Debug + Release). - Document the required NSCameraUsageDescription host-app key in the README pre-requisites. - Clarify that .cameraAndMicrophone is intentionally denied; keep the doc comment ASCII-only. ENG-5947, ENG-5978
- ci: build Passive-Example in samples_build (the only example target that relies on the new INFOPLIST_KEY_NSCameraUsageDescription build setting, so the change is now exercised in CI) - docs: de-duplicate the microphone-denial rationale, keeping it inline - docs: clarify the README camera-usage note wording ENG-5947, ENG-5978
Address multi-reviewer consistency pass: - Revert podspec 3.1.0->3.0.1 and drop the CHANGELOG entry. The recent 3.x cadence bumps the version in a dedicated release PR, and bumping here left Example/Podfile.lock stale (3.0.1) against the repo invariant that any podspec version change regenerates the lock. Deferring fixes both. - Trim the requestMediaCapturePermissionFor doc comment to the file's terse one/two-line norm and drop the non-ASCII em-dash; the camera-only/mic rationale already lives in the inline comment.

WKWebView auto-denies getUserMedia, so the camera-based liveness challenge can't start the camera on iOS. This adds the WKUIDelegate permission method to grant it, camera only since the challenge doesn't use the microphone (which keeps NSMicrophoneUsageDescription out of it). It also adds NSCameraUsageDescription to the example apps and a short README note that integrating apps need to declare it. Liveness requires iOS 15.
Verified the SDK framework builds and the full unit suite passes (123 tests).
