Some Xcode challenges seem to crop up repeatedly. Today, I thought I'd share a few solutions that you might find helpful to integrate into your workflow.
Challenge: When you move an Xcode project to a new folder, all your file references die.
Solution: Avoid those red "can't find" file references by changing the way each group defines its location. If you're pulling in a suite of code from another folder, select it and open the File inspector (View > Utilities > Show File Inspector). Choose "Absolute Path" from the Path pop-up.
