Compass Compass shouldn't require the Command Line Developer Tools, just a compatible ruby environment.

When the iOS Golden Master (GM) release is sent to developers, Apple also opens up app submissions for the new OS. They also appear to segment out releases targeted for the new OS so that apps are available, though there is no solid evidence for this. For example, iOS 8 was released on Sept 17th, 2014.

This seems to work for XCode 5, remove --dry-run to actually perform copy. sudo rsync -ai --exclude subversion\* --exclude SVN\* /Applications/Xcode.app/Contents/Developer/usr / sudo ln -sf /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild /usr/bin/ Or go to https://developer.apple.com/downloads/ and search for "xcode" - there are downloadable ...

You need to make your apps in Xcode 7 to run on your iDevice without any developer program. You need to sign in with your Apple ID. For more details visit the Xcode 7 site. It's in beta 6 now. https://developer.apple.com/xcode/ If you need Xcode 6 or lower, paying the fee is the only alternative.
