Add iPad target to existing iPhone project or make universal = no touches

I would check the view debugger to see if there is a superview with zero size somewhere due to a layout problem (e.g. incorrect or missing constraints). By default views do not clip to bounds, but their subviews won't receive touches outside the bounds.

I'd be surprised if the layout was that easy to repurpose, but you should get hits somewhere, I think.

I'd start by deleting and redoing the file's owner connections, then perform a clean build folder, then see if that makes a difference in touch zones.

I'd also wonder if it would be better to create a new uni project and add the older assets to it instead of attempting to modernize, but that's just me 😉

So the view debugger showed one view with an unexplained 2400pt height. Once I corrected that, all was well.

Oddly, the other project that had the same problem also had a 2400pt high view. Projects are totally unrelated, other than both being older with XIBs. I can only assume this was some goofup in Xcode when adding the iPad target.

Well, that was a red herring. The problem reappeared when testing the app on different iPad models in the simulator. The only one that works is the iPad Pro 9.7; on all the others, no touches are recognized. I am starting to think this is some oddness with the simulator.

I don't think it has anything to do w/the simulator. Converting has never been as simple as toggling the device family.
