Creating Unwind Segues in Swift 3 and 4

Unlike (normal forward) segues, I find the process of setting up unwind segues in an IOS Swift project not that intuitive. Hence, whenever I haven’t used one in a while, I need a little reminder on how to get it hooked up.

There’s a nice little write up by developer Luna An here that sums it all up very neatly.

More Xcode 9 Oddities – Cannot load underlying module for [some pod]

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:

xcode-oddities-1

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.

 

Xcode 9 Oddities – External Keyboard Not Working in Simulator

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!
