And Well, It Runs Navigating the Project (and Xcode) Managing the workflow within Xcode is key to being efficient in developing and enhancing any project. Knowing how to navigate the editors without leaving the keyboard can improve your speed of development and, well, is just plain cool. Xcode 4 has introduced some nice new features that take advantage of the new interface. It has also changed a number of common keyboard shortcuts from Xcode 3.

If the data says something isn’t running poorly, chances are it isn’t. When you find the bottleneck or poor performance, find one or two metrics to measure. The key to tuning is always metrics. Ensuring the changes you are making only tweak that one metric will make for a successful tuning session. Another rule of thumb is to change one thing at a time. Changing multiple things simultaneously can cause problems because the two changes might cancel themselves out or introduce unknown errors. We’re usually working with very complex systems with many moving parts, and introducing changes can introduce bugs.

The Flat view takes any structure out of the listing and lets you see a raw listing of files. Now take a look at the built-in diff viewer, which shows the changes that will be committed. You can copy the source changes by right-clicking either editor view. Doing so puts a patch-formatted diff in your pasteboard. Since we’re good developers, we’re going to put something meaningful in our commit message like: “changes” or “Continued development”. Go ahead and enter a commit message and click commit.
