Summary. Apple announced iOS 27 at WWDC 2026 on June 9, 2026, and shipped the first developer beta on June 8, followed by developer beta 2 on June 22. The public beta is expected around July 14, 2026, a release candidate should land near September 7, and the general release is expected around September 14, 2026, alongside the new iPhone lineup. The developer beta needs a $99-per-year Apple Developer account, while the public beta is free through Apple's Beta Software Program. iOS 27 runs on the iPhone 11 and later, though the new Siri AI and Apple Intelligence features require an iPhone 15 Pro or later. This page tracks every confirmed and expected date, so you know exactly when to test and when to upgrade.
The short answer for most people: the public beta is days away in mid-July, and the finished iOS 27 arrives in the second week of September. If you rely on your iPhone daily, wait for September; if you want an early look on a spare device, mid-July is your moment.
The iOS 27 timeline at a glance
Apple runs iOS releases to a predictable calendar, and 2026 is following it closely. The developer beta opened the day of the WWDC 2026 keynote, the public beta follows in mid-July, betas continue through the summer, and the finished release ships in September with the new iPhones.
| Milestone | Expected date (2026) | Who it is for |
|---|---|---|
| WWDC 2026 keynote | June 9 | Everyone (announcement) |
| Developer beta 1 | June 8 | Developers, $99/year account |
| Developer beta 2 | June 22 | Developers |
| Public beta | Around July 14 | Anyone, free via beta.apple.com |
| Ongoing betas | July to early September | Testers |
| Release candidate | Around September 7 | Final testing |
| General release | Around September 14 | Everyone |
When is the iOS 27 public beta?
The public beta is the date most people are waiting for, and it is expected on or around Tuesday, July 14, 2026, per 9to5Mac's tracking and Forbes. It arrives free through Apple's Beta Software Program: sign up at beta.apple.com, then open Settings, General, Software Update, and Beta Updates on a compatible iPhone to opt in.
A word of caution that applies every year: betas carry bugs and battery issues, so they do not belong on the iPhone you depend on. Use a spare device, and take an archived backup first. If you manage devices for a team, our iOS 27 public beta team checklist and fleet readiness checklist cover how to test it safely.
When is the iOS 27 general release?
The finished iOS 27 is expected around Monday, September 14, 2026. Apple has released its major iOS update in the second week of September for years, and 2026 is expected to match, with the release coming alongside the new iPhone lineup, per MacRumors' iOS 27 roundup. Before that, a release candidate, the near-final build, should appear around September 7, and Apple usually confirms the exact public date at its early-September event, roughly a week ahead.
So the practical guidance is simple. If you want the stable version, it lands in mid-September. If you want to try features early and can tolerate rough edges, the public beta from mid-July gives you two months of preview first.
What happens between the beta and launch
The stretch from mid-July to mid-September is not empty; it is where iOS 27 goes from rough to ready. After the public beta lands around July 14, Apple typically ships a new beta build every one to two weeks, each fixing bugs and adding polish, until the software is stable enough to release. Following the builds is the best way to judge when iOS 27 is safe for your own use.
The early betas are where the visible problems live. Beta 1 and 2 commonly bring warmer devices and faster battery drain as Apple tunes performance, and features can change between builds. By August the betas usually settle, and the app compatibility issues that matter to daily users start to clear as developers update their apps against the new release.
The release candidate, expected around September 7, is the near-final build. It is the version Apple intends to ship unless a last-minute bug forces a change, so it is the safest beta to try if you want a preview close to the finished product. About a week later, at its early-September event, Apple typically confirms the exact public release date and the new iPhones that launch with it.
For a personal device, let the calendar do the work: try the public beta in July on a spare phone if you are curious, watch the betas stabilise through August, and upgrade your main iPhone when the general release arrives in mid-September. For a business, the same window is your test runway, and the earlier you start on beta hardware, the less you scramble at launch. Our iOS 27 enterprise rollout plan breaks the whole beta-to-launch period into stages.
Which iPhones will get iOS 27?
Compatibility widened this year rather than narrowing. iOS 27 runs on the iPhone 11 and later, keeping the A13 Bionic as the minimum chip, per AppleInsider. The phones that lose support are the iPhone XS, XS Max, XR, X, 8, 8 Plus, and the first-generation iPhone SE.
There is one important split. The new Siri AI and Apple Intelligence features need an iPhone 15 Pro or later, because they require the A17 Pro chip and 8 GB of RAM, per Macworld. Older supported iPhones get the iOS 27 interface, the Liquid Glass design, and security updates, but not the AI layer.
| iPhone tier | Examples | iOS 27 | Siri AI / Apple Intelligence |
|---|---|---|---|
| AI-capable | iPhone 17 Pro, 16 Pro, 15 Pro | Yes | Yes |
| Modern | iPhone 16, 15, 14, 13 | Yes | No |
| Older supported | iPhone 12, 11, SE (2nd gen) | Yes | No |
| No longer supported | iPhone XS, XR, 8, SE (1st gen) | No | No |
What is new in iOS 27?
The headline change is Siri. Apple rebuilt the assistant as Siri AI, part of a wider Apple Intelligence update, and paired it with a refined "Liquid Glass" interface, per the WWDC 2026 coverage. Apple's own figures claim new photos appear 70% faster and AirDrop transfers run 80% faster than on iOS 26. Other additions include dual phone numbers on one iPhone, dual-camera FaceTime, and Markdown support in Notes.

Should you install the iOS 27 beta?
For most people, the answer is not on your main phone. The public beta is a genuine preview, but it is unfinished software, and early builds have shown warmer devices and faster battery drain. If you have a spare iPhone 11 or later, the mid-July public beta is a safe way to explore. If you only have one iPhone and rely on it, wait for the September release, which is the version built for everyday use.
For teams and businesses, the calculation differs: the beta window is exactly when you validate your apps and device management before the fleet upgrades. That is worth doing on test hardware from July, rather than reacting in September.
