Is it possible to increase the font size in Interface Builder? The ridiculously small side of those fonts, specially on the Inspector, are giving me headaches.
You can try using the wonderful AppleDisplayScaleFactor, but I wouldn’t be very surprised if a lot of things stopped working correctly. So it will correctly increase the font size (along with everything else), but the headaches would probably remain. Or get much, much worse. But hey, you asked!

Unfortunately no. File an enhancement request.
