Quick answer
WWDC 2026 ran from 8 to 12 June 2026. Apple announced iOS 27 at the keynote on 8 June at 10:00 a.m. Pacific and released developer beta 1 (24A5355q) the same day. Eight betas and a release candidate later, iOS 27.0 shipped on 14 September. Today the public release is iOS 27.0.1 and the beta track is iOS 27.2, now at beta 4.
This page was first published ten days before the keynote, when Apple had confirmed the date and little else. It now records how the timeline actually played out, and where the pre-WWDC expectations were right or wrong.
What Apple confirmed for WWDC 2026
Apple held its Worldwide Developers Conference from Monday 8 June to Friday 12 June 2026, with the keynote and the Platforms State of the Union on the first day. The conference was free to follow online, through the Apple Developer app and Apple's website among other channels, and Apple ran a limited in-person event at Apple Park for selected developers and students.
Ahead of the event Apple said WWDC would highlight "AI advancements and exciting new software and developer tools." At the keynote it announced six 27-series releases: iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27 and visionOS 27. For a fuller account of the event itself, see our WWDC 2026 guide.
The iOS 27 beta timeline, build by build
Developer beta 1 went out on keynote day, following the pattern of earlier years. Here is every iOS 27 build Apple has published for iPhone since then:
| Release | Build | Date |
|---|---|---|
| iOS 27.0 beta 1 | 24A5355q | Monday 8 June 2026 |
| iOS 27.0 beta 2 | 24A5370h | Monday 22 June 2026 |
| iOS 27.0 beta 3 | 24A5380h | Monday 6 July 2026 |
| iOS 27.0 beta 4 | 24A5390f | Monday 20 July 2026 |
| iOS 27.0 beta 5 | 24A5408d | Monday 10 August 2026 |
| iOS 27.0 beta 6 | 24A5418b | Monday 17 August 2026 |
| iOS 27.0 beta 7 | 24A5424a | Monday 24 August 2026 |
| iOS 27.0 beta 8 | 24A5430a | Monday 31 August 2026 |
| iOS 27.0 RC | 24A435 | Wednesday 9 September 2026 |
| iOS 27.0 | 24A437 | Monday 14 September 2026 |
| iOS 27.2 beta 1 | 24B5084k | Wednesday 16 September 2026 |
| iOS 27.2 beta 2 | 24B5089g | Monday 21 September 2026 |
| iOS 27.0.1 | 24A446 | Monday 28 September 2026 |
| iOS 27.2 beta 3 | 24B5099f | Monday 5 October 2026 |
| iOS 27.2 beta 4 | 24B5110a | Tuesday 13 October 2026 |
The rhythm is easy to read. Betas 1 to 4 came two weeks apart. After a three-week gap, betas 5 to 8 arrived weekly through August, which is the usual sign that a release is close. The release candidate followed on 9 September, and the final build five days later. Nearly every release landed on a Monday. Our iOS 27 beta release timeline tracks the milestones, and the iOS 27 release time zone chart converts release times to your clock.
Where the 27-series stands today
As of 19 October 2026, these are the newest builds for each platform:
| Platform | Latest beta | Latest public release |
|---|---|---|
| iOS | 27.2 beta 4 (24B5110a), 13 Oct | 27.0.1 (24A446), 28 Sep |
| iPadOS | 27.2 beta 4 (24B5110a), 13 Oct | 27.0.1 (24A446), 28 Sep |
| macOS | 27.2 beta 4 (26B5112a), 13 Oct | 27.0.1 (26A434), 28 Sep |
| watchOS | 27.2 beta 4 (24S5112a), 13 Oct | 27.0.1 (24R365), 28 Sep |
| tvOS | 27.2 beta 3 (24K5103f), 5 Oct | 27.0 (24J361), 14 Sep |
| visionOS | 27.2 beta 4 (24N5114a), 13 Oct | 27.0.1 (24M372), 28 Sep |
Apple does not publish its beta schedule in advance, so there is no confirmed date for the next 27.2 beta or for the final 27.2 release.
What the pre-WWDC predictions got right and wrong
Before the keynote, this page and most coverage built a timeline from Apple's past pattern. Here is how it held up:
| Expectation in May 2026 | What happened |
|---|---|
| Developer beta 1 on keynote day, 8 June | Correct. Build 24A5355q arrived on 8 June |
| Developer betas roughly every two weeks | Correct for betas 1 to 4, then weekly in August |
| Public release around Monday 14 September | Correct. iOS 27.0 shipped on 14 September |
| iPhone 11 series and iPhone SE (2nd generation) dropped | Wrong. Every iPhone that ran iOS 26 runs iOS 27 |
| macOS 27 ends Intel Mac support | Correct. The macOS 27 restore image covers Apple silicon Macs only |
The device list is the one to remember. iOS 27 runs on 33 iPhones, the iPhone 11 and later plus the iPhone SE (2nd and 3rd generation). Our iOS 27 supported devices list has every model, and the Mac side is covered in macOS 27 supported Macs.
What was reported before the keynote
In the weeks before WWDC, the reporting centred on Siri and Apple Intelligence. This is a record of what was expected, not a list of what shipped:
- A rebuilt, chat-style Siri, reportedly running on a custom Google Gemini model and shown in the Dynamic Island.
- A system-wide "Search or Ask" bar opened by swiping down from the top centre of the screen.
- A choice of outside AI services, with Gemini and Claude reported as options alongside ChatGPT.
- New Photos editing tools named Extend, Enhance and Reframe, joining Clean Up.
- Shortcuts that could be built from a plain-English description, and a more prominent Writing Tools with grammar checking.
- Refinements to the Liquid Glass design and a release framed around stability and performance.
Pre-launch reports often change shape by the time a feature ships, and some features slip to later updates. To see what Apple actually delivered, use our iOS 27 features list rather than this list.
How to join the iOS 27 beta now
You did not miss anything by skipping beta 1. The 27.2 beta track is open, free with any Apple Account, and needs no configuration profile or paid developer membership.
- Make a backup on a Mac or PC and archive it, so a later backup cannot overwrite it.
- For the developer beta, sign in once in the free Apple Developer app. For the public beta, enroll at beta.apple.com.
- Open
Settings › General › Software Update › Beta Updates. - Choose iOS 27 Public Beta or iOS 27 Developer Beta.
- Go back one screen and install iOS 27.2 beta 4 when it appears.

How to leave the beta
There are two ways out. To stop receiving betas without erasing anything, turn off Beta Updates: the iPhone keeps its current build and moves to the next public release with a higher version number. To go back to iOS 26 now, restore iOS 26.6.1 RC (23G82), which Apple is currently signing, from Finder on a Mac or the Apple Devices app on a PC. That erases the phone, and you then restore the backup you made before installing the beta. A backup made on iOS 27 cannot be restored onto iOS 26.
What to do next
If you want to run iOS 27 today, the public release needs nothing more than Settings › General › Software Update. If you want the 27.2 builds as they arrive, follow our iOS 27 beta download guide for the full setup on your iPhone.
Frequently asked questions
When was WWDC 2026?
WWDC 2026 ran from Monday 8 June to Friday 12 June 2026. The keynote opened the conference on 8 June at 10:00 a.m. Pacific time, and Apple announced iOS 27 there alongside iPadOS 27, macOS 27, watchOS 27, tvOS 27 and visionOS 27. The conference was free to follow online, with a limited in-person event at Apple Park for selected developers and students.
When did the iOS 27 beta come out?
Apple released iOS 27 developer beta 1, build 24A5355q, on 8 June 2026, the same day as the WWDC keynote. Seven more developer betas followed through 31 August, then the release candidate on 9 September. Apple also runs a free public beta through beta.apple.com. Both tracks are free with an Apple Account and need no configuration profile.
When was iOS 27 released to the public?
iOS 27.0 (build 24A437) reached the public on Monday 14 September 2026, five days after the release candidate. Apple followed it with iOS 27.0.1 (24A446) on 28 September 2026, which is the current public release. Both install on every supported iPhone through Settings › General › Software Update, with no beta enrollment needed.
What is the latest iOS 27 beta?
The latest beta is iOS 27.2 beta 4, build 24B5110a, released on 13 October 2026. The 27.2 track started on 16 September with beta 1, two days after iOS 27.0 shipped. iPadOS 27.2 beta 4 has the same build number, and macOS 27.2 beta 4 (26B5112a) and watchOS 27.2 beta 4 (24S5112a) arrived the same day.
Did iOS 27 drop any iPhones?
No. Before WWDC several reports, including this page, expected the iPhone 11 series and the iPhone SE (2nd generation) to lose support. That did not happen. iOS 27 runs on 33 iPhones, which is every iPhone that ran iOS 26: the iPhone 11 and later plus the iPhone SE (2nd and 3rd generation). The iPhone XS, XS Max, XR and older stay unsupported.
Does macOS 27 support Intel Macs?
No. Reports before WWDC said macOS 27 would drop Intel Macs, and the macOS 27 restore image confirms it: it covers Apple silicon Macs only, from the first M1 models to the newest M5 and M6 machines and the MacBook Neo. The current public release is macOS 27.0.1 (26A434), and the beta track is macOS 27.2.
Can I still join the iOS 27 beta now?
Yes. On a supported iPhone open Settings › General › Software Update › Beta Updates, choose iOS 27 Public Beta or iOS 27 Developer Beta, go back and install. For the developer beta, sign in once in the free Apple Developer app. For the public beta, enroll at beta.apple.com. Archive a computer backup first, because a beta backup cannot be restored onto an older iOS version.
