Apple signals a major shift in iOS design with a rumored split‑screen feature slated for iOS 27. Leaker Fixed Focus Digital claims the company is building a “Parallel View” system that automatically reflows apps for wide, landscape displays, mirroring Huawei’s HarmonyOS approach but without developer changes in the future update later.

Parallel View would address iPhone apps’ long‑standing narrow‑screen bias, a problem that becomes visible on the foldable iPhone’s 7.8‑inch inner panel. Without a system‑level fix, apps would appear letterboxed, breaking user experience across a device that Apple pairs with the upcoming iPhone 18 Pro in the fall release of 2026 and future.

Apple already applies a similar landscape adaptation at the system level on iPadOS, yet iOS has lacked such a mechanism. Fixed Focus Digital noted that the company’s existing approach is “excellent,” but large‑screen support has consistently fallen short, prompting the new feature for foldable devices in 2026 and beyond today.

WWDC 2026 will likely unveil iOS 27 alongside the iPhone 18 Pro lineup, cementing Apple's push toward versatile form factors. The Parallel View rollout could standardize app layouts across all iPhone screens, reducing developer overhead and smoothing the transition to foldable hardware in the coming months and beyond for consumers and developers worldwide today.
