            Bug ID: 212933
           Summary: [iOS] Gamepad API Game Controller Support
           Product: WebKit
           Version: Safari 13
          Hardware: iPhone / iPad
                OS: iOS 13
            Status: NEW
          Severity: Major
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: goehdavi at amazon.com

Testing on iOS and iPadOS 13.4.1 has revealed that Xbox and PS4 controllers are detected and input events are received over Bluetooth, but some buttons are missing and D-Pad buttons are received as axes input. Looking at the WebKit GameControllerGamepad (https://github.com/WebKit/webkit/blob/89c28d471fae35f1788a0f857067896a10af8974/Source/WebCore/platform/gamepad/cocoa/GameControllerGamepad.mm) implementation on GitHub it appears that the WebKit Game Controller Framework (https://developer.apple.com/documentation/gamecontroller) integration doesn’t include the new controller buttons added to GCF last year (https://developer.apple.com/videos/play/wwdc2019/616/). For instance, buttonMenu (https://developer.apple.com/documentation/gamecontroller/gcextendedgamepad/3237238-buttonmenu) appears to be missing. Can WebKit fix the the DPad and add the additional buttons?
