Error on Xcode 10 building Fun Facts App

In my output section I am seeing this error pop up. I am following instructions and running the simulator as iPhone 6s; however, it is not an option for "view as." It is being viewed as iPhone 8. I still get the error if I run the simulator as iPhone 8. There are a lot of differences with Xcode 10 and it's been slowing me down a lot when following the videos.

Any thoughts?

Oh dear, the libMobileGestalt error... I'd like to know what causes that, too. All I can say is it happened to me once, then I just fudged around a bit and it went away. No idea what I did or why. I think it had something to do with the interaction between the viewController and IB, but I'm not sure.

I should clarify this error shows in the debug console. If I change the simulation to iPhone XR, the error goes away. I don't think Xcode wants to play with iPhone 6s anymore (what's instructed in the video).

Did anyone ever get an answer for this? I'm getting this error even if I switch to iPhone Xr

I have just been running simulations in iPhone XR. You might try copying your code, deleting and pasting back in to see if it refreshes its atttude.

Thanks for responding Deysha. I was able to solve it by uninstalling and installing a earlier version of Swift 9
