IOS 19 WILL MAKE A DESIGN CHANGE THAT'S PERFECT FOR LARGE IPHONES, PER LEAK

Summary from the TLDR Design newsletter

iOS 19, set to debut at WWDC, is rumored to introduce a usability upgrade for large iPhone users by shifting the in-app search bar to the bottom of the screen. This change will be aimed at making one-handed navigation easier, especially on bigger models like the Pro Max. Mockups showed apps like Messages and Music with the redesigned search placement, suggesting Apple had prioritized function as well as form in the upcoming update.
