Looking for a less awkward way to open the other developer tools (like Instruments, Icon Composer, etc.) than Xcode’s Open Developer Tool menu? How about the more familiar Dock shortcuts? Here’s how.
Xcode 4.2 is now a self-contained app installed in the Applications folder. All the additional developer tools are inside the Xcode bundle under /Applications/Xcode/Contents/Applications. You could launch each one and reposition their icons on the Dock so they stay put or right-click the dock icon, and choose Options > Keep in Dock from the context menu. Alternatively, you could right-click the Xcode icon in the Applications folder and choose Show Package Contents, open ../Contents/Applications, then drag the desired apps to the Dock.
That’s it! Happy coding!
