If you’ve just tried the application loader, clicked ‘New in app purchase’, got to the end (or tried to save the configuration), you will undoubtedly see this confusing error message.
Of course the file doesn’t exist, we’re just creating it. What are you on about Apple?
Here’s how to fix it.
At the top of the window – you should see this:
Click on Untitled, and type the name in you wish to save as, here I typed xxx.
Now, the title bar looks like this:
You can now save the file.
Really annoying eh?
