Idk, I feel like these coding assistant features aren’t that hard to add, but can provide a lot of value to developers. Most or all popular IDEs now support similar features.

I don’t disagree that Apple could use a major focus on bug fixing across their platforms right now though.

Yeah, I'd like to see another OS release like to Snow Leopard (10.6.x) which had as a prime focus simplification and so forth w/o adding many (any?) features.
