The iOS settings app has some inconsistencies I want to bring up to discuss the reasoning for their choices.
Settings > General > Language & Region > Regionuses a modal with a filter input.
Settings > General > Language & Region > Calendaruses a push.
Settings > General > Date & Time > Time Zoneuses a push with a search input.
I can understand why #2 uses a push because it sort of acts like radio buttons except you go to a different page. But #1 and #3 confuse me. Even though they use different type of search/filter, why do they navigate differently?
