I have a project built on Xcode 7.2 and downloaded the newer version 7.3. I need the steps on how to run or load the new Xcode with the project I built on 7.2. Any help appreciated. I knew to this situation.
Using project from Xcode 7.2 to using it on the Xcode 7.3
First, be sure you have a protected backup of that project you can use should you encounter a situation while editing that you can't easily recover from. Be sure you know the project location in the Finder.
Run Xcode, then use the File/Open... menu - navigate to the project's folder and locate the <name>.xcodeproj file and open it. This should result in the project available for editing, building, etc.
