WatchKit apps/extensions and iOS backwards compatibility
问题 I have an iOS app with its Deployment Target set to iOS 6.1 version, and the Base SDK to latest iOS. I've added both the Watchkit app and WatchKit extension targets to the project, but I need to understand how will this affect a future submission to the App Store: 1) Are two executable files generated? One for the iOS app + WatchKit extension, and another for the WatchKit app? Or is all packaged in an unique executable file? 2) Will it be automatically handled the iOS version of the device
