The Unity HockeySDK for iOS Unity plugin removes the Feedback feature. The reason for this is that iOS 10 requires developers to add a usage string to their Info.plist in case they include the photos framework in their app. If this string is missing, the app will be rejected when submitting the app to the app store. As HockeyApp's Feedback feature includes a dependency to the photos framework. This means that if you include HockeyApp into your app, adding the usage string would be a requirement even for developers who don't use the Feedback feature. If you don't use Feedback in your app, simply upgrade HockeySDK to version 1.1.5. If you need the feedback feature you have to use version 1.1.2 or lower. If you are using an older version of the SDK, you must add a NSPhotoLibraryUsageDescription to your Info.plist to avoid a AppStore rejection during upload of your app.HockeySDK-Unity-iOS implements support for using HockeyApp in your Unity iOS applications.
