That said, you don’t really have a choice if you want to support iPhone X, which you should.

  All 64 bit apps are supported by iPhone X. You only need to upgrade to XCode 9 if you want a custom layout for the black band or whatever people are calling it. I'm sure many companies will update their apps, but I can't imagine the experience will be that much better in most cases.

    Since the aspect ratio of the iPhone X is also taller, running unoptimised apps on the X will be a pretty bad experience - just as running iPhone 4 style apps on the iPhone 5 was a pretty bad experience.

      Is it a different size class than iPhone 8? I guess it depends on your autolayout setup. I still don't think most apps will make good use of the notch.
