Saving all of your project data can be important to do, but if you do save it, finding it later on can be nearly impossible. This is when you should know more about why you should be using the PBXPROJ - Xcode Project Data File. When you see this file, you will know where all of your data is stored at and what exactly you should be doing to get it to work properly. Without the PBXPROJ - Xcode Project Data File you can still find your data, but you will have to remember the name and extension you used.
