Xcode App Running Issue
Xcode 8.1 is now available
Note from Apple News:
You can now download Xcode 8.1 from the Mac App Store. This version includes the latest macOS SDKs for building apps that use the all-new Touch Bar on the new MacBook Pro. To develop apps for the Touch Bar, you’ll need a Mac running Xcode 8.1 on macOS Sierra 10.12.1 (12B2657) or later.
There is an option in order to do not download full xcode, you need to download files from this topic (in Update comment)
Then you need to copy 10.1 (14B65) folder to/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
so the full path will look like:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.1 (14B65)with two files in it: DeveloperDiskImage.dmg.signature and DeveloperDiskImage.dmg
It worked fine for me.
