When Apple announced Xcode 6 at WWDC14, one feature in particular excited me namely Xcode Live Rendering. This means an end to all the empty white views in place for our custom views.
But as Apple states in What’s new in Xcode 6, it is intended for hand-written UI code.
Live rendering within Interface Builder displays your hand-written UI code within the design canvas, instantly reflecting changes you type in code.
This is unsatisfying for me, since I went all in on Interface Builder when Storyboards and Auto Layout were introduced. Also I find it strange that Apple has not made it easier to do custom views using nibs.
