Rejoining iOS dev after a long break, what should I relearn?

I’ve been building iOS apps since 2011, took a 4-year break, returned with two new apps, and it feels like organic visibility and indexing have changed drastically compared to earlier releases.

Has anyone else noticed slower indexing, fewer automatic mentions, and almost zero organic traction—has discovery changed, or is it just saturation?
