Statecharts: hierarchical state machines

A frustrated iPhone owner logs 395 points with a tale of an app that reinstalls itself every day, drawing 150 commenters who offer debugging advice and rage against Apple’s walled-garden oversight. The culprit was a calendar widget that self-reinstalled 14 times in a single week, consuming 2.3 GB of storage per incident. A 30-second settings change solved it for 89% of users, yet iOS 18 still lacks a permanent fix.
