iPadOS

iPadOS. It is a mobile operating system developed by Apple Inc. exclusively for its iPad line of tablet computers. Announced in 2019, it branched from iOS to provide features tailored for the larger display and capabilities of the iPad, such as enhanced multitasking and support for peripherals like the Apple Pencil. The system shares its core with iOS but introduces a distinct user interface and functionality designed to leverage the iPad's potential as a productivity device.

History

The evolution began with the original iPad in 2010, which launched running a version of iPhone OS 3.2. For nearly a decade, the iPad shared its operating system with the iPhone, under the iOS brand. At the WWDC 2019 keynote, Apple Inc. announced the separation, introducing it as a distinct platform to better address the unique form factor. The first version, based on iOS 13, was released to the public on September 24, 2019. Subsequent major releases have paralleled iOS but added exclusive features, such as the introduction of the Apple Silicon-powered iPad Pro and deeper integration with the Mac ecosystem through technologies like Universal Control.

Features

It introduces several features distinct from iOS to take advantage of the iPad's screen real estate. The Home Screen supports widgets and allows for a denser arrangement of app icons. Enhanced multitasking is central, with systems like Split View, Slide Over, and Stage Manager allowing multiple app windows to be open simultaneously. It offers improved file management through the Files app, with support for external drives, SMB servers, and compressed archives. The Apple Pencil is deeply integrated, with system-wide markup, a redesigned tool palette, and low-latency performance. Other key features include a desktop-class Safari browser, support for custom fonts, and advanced text editing gestures.

Hardware compatibility

It runs on a wide range of iPad models. The initial release supported all iPads capable of running iOS 13, including the iPad Air 2 and later, the iPad 5th generation and later, all iPad Pro models, and the iPad Mini 4 and later. As with iOS, support for older devices is gradually dropped with new major versions; for example, iPadOS 16 ended support for the iPad Air 2 and iPad Mini 4. The operating system is optimized to leverage the power of newer chipsets, such as the A12Z Bionic in the 2020 iPad Pro and the Apple M1 and M2 chips in later iPad Pro and iPad Air models, enabling features like Stage Manager and full external display support.

Development

Development is managed by Apple Inc.'s Software Engineering team, led by senior vice president Craig Federighi. It is built on the same foundational layers as iOS and macOS, including the Darwin core and the XNU kernel. The SDK for developers is part of Xcode, and new versions are typically previewed at the annual WWDC conference. A key development focus has been bridging the gap with macOS, exemplified by project Marzipan (later UIKit for Mac and Mac Catalyst), which allows developers to more easily port iPad apps to the Mac. The App Store remains the exclusive source for applications, with apps often offering universal binaries or specific iPad-optimized versions.

Reception

Initial critical reception was generally positive, with reviewers from publications like The Verge and TechCrunch praising the move to differentiate the iPad's software from the iPhone. Features like the improved Files app and desktop Safari were highlighted as significant steps toward professional use. However, some critics, including those from Ars Technica, argued that the multitasking system remained complex for average users. The introduction of Stage Manager in 2022 was met with mixed reviews; while powerful, it was criticized for being buggy at launch. Overall, it is seen as crucial to Apple Inc.'s positioning of the iPad as a viable computer alternative, competing with devices running Microsoft's Windows 11 and Google's ChromeOS.
