Alcatraz is an open-source package manager for Xcode 7. It lets you discover and install plugins, templates and color schemes without the need for manually cloning or copying files. It installs itself as a part of Xcode and it feels like home. Select Package Manager from the Window menu, then check or uncheck packages to install or remove them. You'll need to restart Xcode after installing certain packages, as indicated after installation. Please note that plugins are not supported by Xcode...
