I wonder if the reason there is no corresponding Xcode for the iOS 10.1+macOS 10.12.1 release is that they want to hold the official reveal of the magic toolbar. Surely the latest Xcode macOS SDK will have some sort of APIs for configuring the display/graphics/icons on the magic toolbar. Sucks if you're developing for iOS, because unless you want to side-load beta versions of Xcode, you will need to choose between being able to debug on the device or being safe from the remote code execution bug in the JPEG decoder on anything less than iOS 10.1...
