How to add a 'Copy Files build phase' to my Target
In Xcode 4, the option is in Editor->Add Build Phase.
The Copy Files build phase then appears in the Project Navigator and you can add things to it by clicking the plus.
In Xcode 5, you have to click on your target, then on Editor (menu bar) --> Add build phase --> Add Copy Files Build Phase:
Right-Click on your target in XCode, select add "new build phase" and then "new copy files build phase".
A "DIY" answer: Go to Xcode --> Help --> type your query, e.g., "add copy". And Xcode helpfully points you in the right direction.
