Mark your calendars: iOS 27 Developer Beta drops June 8, 2026 — the same day as Apple's WWDC keynote. If you're planning to install the beta, here's everything you need to know about timing, how to watch, and what to expect.
I've been covering iOS releases since iOS 12, and the pattern is remarkably consistent. Let me break down exactly when each phase of iOS 27 arrives so you can plan accordingly.
Complete iOS 27 Release Timeline
WWDC 2026 Keynote Start
iOS 27 officially announced. First look at new features.

Available immediately after keynote ends (~12-1 PM PT).

WWDC 2026: What to Expect
Apple's Worldwide Developers Conference is where iOS 27 makes its debut. The keynote on June 8 is the main event — a roughly 2-hour presentation covering all of Apple's software updates.
iOS 27
iPhone Fold support, Health+, Siri redesign, performance improvements.
iPadOS 27
Enhanced multitasking, Stage Manager updates, Apple Pencil features.
macOS 27
New system apps, Continuity improvements, M-series optimizations.
watchOS 13
New watch faces, health features, Apple Watch Ultra updates.
iOS 27 Developer Beta
The Developer Beta is the first public release of iOS 27. It drops immediately after the WWDC keynote — usually around 12:00-1:00 PM PT on June 8, 2026.
Who Can Install?
- Paid developers: Apple Developer Program members ($99/year) get immediate access plus developer tools and support.
- Free access: Since 2023, anyone with an Apple ID can install Developer Betas. Go to Settings → General → Software Update → Beta Updates.
Should You Install Beta 1?
Honestly? Probably not on your main phone. Developer Beta 1 is notoriously buggy — apps crash, battery drains fast, and some features simply don't work yet. If you have a secondary device, go for it. Otherwise, wait for Public Beta in July.
iOS 27 Public Beta
The Public Beta arrives in mid-July 2026, roughly 4-6 weeks after the Developer Beta. It's free for everyone and generally more stable.
How to Join Public Beta
- Visit beta.apple.com
- Sign in with your Apple ID
- Enroll your iPhone
- Go to Settings → General → Software Update → Beta Updates
- Select "iOS 27 Public Beta"
- Download and install
iOS 27 Final Release
The stable, public release of iOS 27 arrives in mid-September 2026. This is the version you should install on your primary iPhone.
Apple typically announces the exact release date during their iPhone event in early September. The final iOS version usually drops 1-2 weeks after the event, often the day before new iPhones hit stores.
What Launches With iOS 27?
- iPhone 18 Pro / Pro Max — The new flagship iPhones
