Question

In Xcode 10.1, when I open a newly created storyboard I see

I have the option to specify Xcode 10. But even when I set it, it jumps back to Xcode 9 after I reopen it.

Just wondering if everyone is having the same issue and if there is a reason to use Xcode 10 instead of 9.

Answer 1

I can verify the same behavior, but I wouldn't worry about it. All the setting is telling you is that it's possible to open the storyboard in Xcode 9. You can work with the storyboard in Xcode 10. I can't think of any reason why you would want to make it impossible to open the storyboard in Xcode 9.
