Hi everyone I have a problem. Say you haven't enabled source control. You create a first version in Xcode. You save the first version in a zip file. You continue enhancing your project. You hand the first zip version to somebody else. This person works on that version in the zip file. You delete your enhanced project (throw it into the trash). The other person sends you his new version (in a new zip file). You open up this version. And what do you see? The original version you've created. If you go into the decompressed folder you can see the enhanced version of the other person. Xcode however keeps up opening the original version. This is at first though. On the top manual is selected. If you select automatic it shows the correct enhanced file. How is this solved? Why is Xcode opening up the original version first? Thanks for your answer!
