When would they release iOS 26?
Official release date
Apple released iOS 26 to the public on September 15, 2025, following its announcement at WWDC on June 9, 2025 (Apple Support – official release notes). The release landed within Apple’s traditional September window, aligning with the launch of new iPhone hardware.
Users on iOS 18 who waited for a stable public release got it exactly when Apple’s pattern predicted — but with a completely different version number than expected.
Pre-release announcements
Apple previewed iOS 26 at its Worldwide Developers Conference (WWDC) keynote on June 9, 2025 (Wikipedia – iOS 26 history). The company’s product page describes the update as “bringing a new design, intelligent experiences, and improvements to the apps you rely on every day” (Apple – iOS 26 product page).
Current iOS 26 version timeline
- iOS 26.0 – September 15, 2025
- iOS 26.1 – October/November 2025 (estimated)
- iOS 26.2 – Late 2025 / Early 2026 (estimated)
- iOS 26.5 – May 11, 2026 (Wikipedia – iOS 26 version list)
- iOS 26.6 (preview) – May 26, 2026 (Wikipedia – iOS 26 history)
The implication: Apple is sustaining a steady cadence of point releases, with iOS 26.6 expected imminently. Users on iOS 26.5 should plan for an update within weeks.
While point updates fix bugs and add features, each one also reduces the window to revert to iOS 18 — Apple stops signing older versions within weeks of a new release.
Why has Apple jumped from iOS 18 to iOS 26?
The official reason for the skip
Wikipedia states that Apple moved the version number forward to 26 by “adopting a year-based naming convention across operating systems” (Wikipedia – iOS 26). Under this logic, iOS 26 corresponds to the 2025 release year — effectively aligning the mobile OS version with macOS, watchOS, and visionOS naming patterns.
How Apple numbers iOS versions
Historically, Apple incremented iOS versions by one with each major annual update (iOS 12, 13, 14, and so on). iOS 18 was released in 2024. A year-based alignment would have produced iOS 25 for 2025, but Apple instead jumped to 26. The exact reason for skipping 19 through 25 has not been publicly explained by Apple.
Implications for device support
The version leap does not change hardware compatibility. iOS 26 supports iPhone 11 series and later, as well as iPhone SE (2020) and later (TechRadar – iOS 26 compatibility). The iPhone XS, XS Max, and XR are excluded. The implication: Apple reset version expectations without shrinking the supported device pool — a branding move, not a hardware cut-off.
If Apple formalizes a year-based scheme, future updates may adopt non-sequential numbering, making it harder for casual users to track which version they’re on by number alone.
The pattern: Apple’s numbering leap is a strategic rebranding that signals a new design era while keeping hardware compatibility unchanged.
Is iOS 26.5 out?
iOS 26.5 release date
Yes. Wikipedia lists iOS 26.5 as dated 2026-05-11 (Wikipedia – iOS 26). Macworld’s iOS 26 guide (May 2026) covers iOS 26.5 features, confirming it as the latest stable version as of that guide.
Features in iOS 26.5
Apple Support confirms that iOS 26 includes Apple Intelligence integrated into more places, polls and backgrounds in Messages, custom snooze options (1–15 minute intervals), a Password History timeline, and Markdown import/export for Notes (Apple Support – iOS 26 features). iOS 26.5 likely adds stability refinements and minor feature enhancements on top of these foundations.
How to check your iOS version
Go to Settings → General → About → iOS Version. If you see iOS 26.5, you are up to date as of May 2026. If you see an earlier version, navigate to Settings → General → Software Update and follow the on-screen prompts.
How do you get iOS 26 now?
- Check device compatibility: Your iPhone must be one of the following:
- iPhone 11, 11 Pro, 11 Pro Max
- iPhone 12, 12 mini, 12 Pro, 12 Pro Max
- iPhone 13, 13 mini, 13 Pro, 13 Pro Max
- iPhone 14, 14 Plus, 14 Pro, 14 Pro Max
- iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
- iPhone 16, 16 Plus, 16 Pro, 16 Pro Max, 16e
- iPhone 17, 17 Pro, 17 Pro Max, iPhone Air
- iPhone SE (2nd generation and later)
The pattern: Apple dropped the XS/XS Max/XR, moved the floor to iPhone 11, and included every model from 11 onward through the latest iPhone 17 series.
- Backup your iPhone: Before installing any major OS update, back up your data to iCloud or a computer. Apple recommends this step on its support pages (Apple Support – update guidance).
- Update via Settings: Connect your iPhone to Wi-Fi. Go to Settings → General → Software Update. Tap Download and Install. The process takes roughly 20–40 minutes, depending on your connection speed and device.
What this means: Updating is a simple three-step process, but device compatibility is the first gate.
Should I keep iOS 18 or get iOS 26?
Key differences between iOS 18 and iOS 26
iOS 26 introduces the Liquid Glass design language and deeper Apple Intelligence integration. TechRadar describes it as “a major iPhone operating system overhaul” (TechRadar – iOS 26 review). iOS 18 lacks these design overhauls and the expanded AI features. The trade-off is visual modernization plus AI features versus stability on a known version.
Upsides
- New Liquid Glass design — fresher interface
- Apple Intelligence in more places — smarter Siri, writing tools
- Messages polls and backgrounds — richer chat features
- Password History timeline — better security oversight
- Markdown support in Notes — productivity boost
Downsides
- Possible compatibility issues with older apps (TechRadar – potential issues)
- Reverting to iOS 18 may not be possible after a few weeks (Apple stops signing older versions)
- Battery drain reports on some iPhone 12/13 models
- Learning curve for new control center and design changes
Potential issues with iOS 26
Some users report compatibility issues with older third-party apps after upgrading (TechRadar – iOS 26 performance). Apple’s own support page notes that Communication Safety and Web content filters are enabled by default for existing child accounts ages 13–17 — a change that may catch parents by surprise (Apple Support – Communication Safety).
Reverting from iOS 26 to iOS 18
Apple stops signing older iOS versions within a few weeks of releasing a new one. Once signing stops, you cannot downgrade. The window to revert from iOS 26.0 to iOS 18 closed in October 2025. Users still on iOS 18 today should weigh the decision carefully — upgrading means committing for the long term.
Timeline

- — iOS 26 released to public (Apple Support)
- — iOS 26.5 is the latest version (Wikipedia)
- — iOS 26.6 preview released (Wikipedia)
The implication: Apple’s release cadence remains consistent, with point updates arriving roughly every few months.

Confirmed facts
- iOS 26 release date: September 15, 2025 (Apple Support)
- Announcement at WWDC: June 9, 2025 (Wikipedia)
- iOS 26.5 released May 11, 2026 (Wikipedia)
- Liquid Glass design name (Apple Support)
- Compatible with iPhone 11 series and later (TechRadar)
- Apple Intelligence integration expanded (Apple Support)
What’s unclear
- Exact reason for numbering jump from 18 to 26 — Apple has not publicly explained it
- Future update schedule beyond iOS 26.6 preview
- Possibility of downgrading to iOS 18 after the signing window closes
- Whether the year-based naming convention will continue for iOS 27
The pattern: While many facts are confirmed, Apple’s silence on the numbering change leaves a gap in understanding.
iOS 26 brings a new design, intelligent experiences, and improvements to the apps you rely on every day. The new design with Liquid Glass brings a more modern, fluid interface to iPhone.
iOS 26 is a major iPhone operating system overhaul that introduces a fresh design language and deeper AI integration across the board.
The pattern is clear: Apple wants users on the latest OS with the newest design and AI features. But the numbering jump — from 18 to 26 — creates confusion that the company has yet to address directly. For anyone still on iOS 18, the decision comes down to whether the Liquid Glass redesign and Apple Intelligence are worth locking into a version you cannot easily leave.
For the iPhone owner in Ireland or anywhere else running iOS 18 today, the choice is straightforward: if you are excited about AI features and a fresh look, update now through Settings. If stability and app compatibility with older tools matter more, staying on iOS 18 is safer — but you will lose access to security patches as Apple shifts focus to iOS 26.x updates.
