iOS 26 swapped the previous buttons of older iPhone software with much larger versions, which made alarms much easier to dismiss or snooze and timers quicker to stop or reset. But Apple seems to have rethought this approach, as stopping alarms and timers now uses a slider as of iOS 26.1.
Sliders require more intention to use, so you're less likely to switch off an alarm by mistake or too quickly. Plus, it's a little dose of nostalgia for users who owned an earlier "swipe to unlock" iPhone.
