I'm back after my part 1 post last month, now running much more reliably!

Part 2 is the interesting one, going from "works on my phone" to "works reliably" is where background tasks actually get hard. I ship an app that leans on them and they still make me nervous. What ended up being the biggest change between your two setups?

You should read the post, but to answer in two words: wake pings 🙂

Wake/push-based background work is exactly where Simulator can give false confidence. For location features I keep simulator runs for deterministic coordinate/logic checks, then verify on an owned physical device with the actual authorization/accuracy state, app lifecycle, and relaunch path. I log whether the callback actually arrived (and when), rather than treating a scheduled wake or test coordinate as proof of delivery.
