Yes — Apple introduced resizability for iPhone apps in the newer WWDC sessions.
In Platforms State of the Union and Modernize your UIKit app, Apple says that in iOS 27:
- iPhone apps can be fully resizable
- This applies when the app is running in iPhone mirroring on Mac
- And also when an iPhone-only app runs on iPad
They also note that apps rebuilt with the latest SDK are automatically opted into resizability.
So the short answer is: yes, resizability was introduced for iPhone apps, but specifically in these newer mirrored/resizable environments rather than as a general always-resizable iPhone home-screen behavior.
