New iOS 19 Leak Allegedly Reveals Updated Icons, Floating Tab Bar, More [Video]

A new leak from Jon Prosser claims to offer the most comprehensive look yet at iOS 19, Apple's next major operating system update. In a video posted to the FrontPageTech YouTube channel today, Prosser showcases a series of design changes allegedly sourced from an internal build. "You're about to see the biggest iOS leak... ever," he declares, positioning this as a significant reveal while addressing skepticism from Bloomberg's Mark Gurman about prior leaks.

The leak highlights new app icons with "a corner radius of about 30, give or take," striking a balance between the square icons of iOS 18 and the circular ones in visionOS, which powers Apple Vision Pro. Prosser explains that earlier builds hid these changes, noting, "Apple was hiding new icons behind the old ones," likely as a precaution if a device were spotted in public. He adds that final icons might still become "perfect circles," though he hasn't seen that yet.

System-wide animations also stand out. Elements like toggle switches and lock screen features "shimmered as you moved the device," enhancing the glassy aesthetic Apple seems to be chasing. The Control Center gets minor updates, with "rounder" brightness and volume sliders. Native apps like Music and the App Store feature a new "Tab View" dock at the bottom, which Prosser calls "way more fluid and bouncy," inspired by Dynamic Island animations. He notes this floating tab bar, internally seen as an evolution of Apple's existing Tab View, will extend to third-party apps for consistency.


In the Messages app, "the search field is now... placed at the bottom of the display" within conversation threads, a subtle shift from prior builds. The Settings app sees a slight visual tweak too, with wider spacing and shadows. "Not different enough to where a normie would even notice," Prosser says, emphasizing that the focus remains on visual refinement over major usability changes.

A new camera feature exclusive to the iPhone 17 Pro and Pro Max emerges as well. The redesigned Camera app, first teased by Prosser in January, will let users "record with your rear-facing camera and front-facing camera at the same time," a capability echoing Samsung's Galaxy S4 from 2013. This ties into earlier claims of a visionOS-style overhaul.

Prosser frames this leak as a rebuttal to Gurman's critique, which called FrontPageTech's prior iOS 19 mockups "outdated or fake or whatever." He stresses that visuals are recreated from scratch to protect sources, a necessity given Apple's practice of forking OS elements across teams to prevent leaks.

iOS 19's public release is set for September; however, Apple is widely expected to debut the software update in June at WWDC.
