When picking what I want to cut, I often take a good hard look at any big feature I'm working on and asking what the MVP of that feature-arc is. Often I'll cut parts of a feature-arc, vs an entire feature itself.
Curtis just spent the last two weeks updating his app Slopes to support Dynamic Type. You might have heard of UIFontMetrics, or you might not have. But you probably didn’t sweat the pixels to make sure you top and bottom margins were baseline-height appropriate ;). He’ll share how he went about adapting to various sizes within dynamic type, and tricks to better mimic the behavior of built-in UI classes (like TableViews).
