File this under more Xcode 9 oddities – a viewcontroller can work perfectly fine one moment, then the next out of the blue, Xcode will throw the following sort of error:
A “Product > Clean” seems to take care of this easily enough, but really hope Apple can get Xcode bugs like these sorted out by the next revision.
Since “upgrading” to Xcode 9 (specifically v9.3 as of time of writing), I’ve noticed quite a number of annoying oddities – or call them bugs. Today’s nuisance is how the external keyboard (i.e. the physical keyboard you type into) will occasionally just stop working. As in, typing into your physical keyboard will not send any input into the IOS app you are running in the simulator.
As with many things tech related, the good ol’ restart seems to be “fix” it – as in just Quit the simulator and re-run your project.
Not too big a deal, but really, stuff like this just shouldn’t be happening. Come on Apple, we deserve better!
