iOS 27.3 is still in beta as of November 5, 2026. Apple posted the first developer beta (build 24C5037i) to the Apple Developer releases page on November 3, 2026 at 10 a.m. Pacific Time, eight days after iOS 27.2 shipped on October 26.
Apple has not announced a release date. Using the gap between the .2 and .3 releases of the last two iOS generations, the final version is most likely to arrive in mid-to-late December 2026. Below is what the first beta tells us, how to read the timing, and why you should not hold off on iOS 27.2 while you wait.
Quick answer: iOS 27.3 beta 1 is out, the release is likely in December
Item | Status as of November 5, 2026 |
|---|---|
Public release | Not released, no date announced |
Developer beta | Beta 1 (24C5037i), November 3, 10 a.m. PT |
Likely release window | Around December 12–26 (estimate based on past gaps, not an Apple announcement) |
Consumer features | Not announced (only developer release notes are public) |
Version to install now | iOS 27.2 (160+ CVE fixes) |
iOS 27.3 beta 1: all six Apple platforms moved together
The Apple Developer releases page listed 27.3 betas for iOS, iPadOS, macOS, watchOS, tvOS and visionOS at the same time, along with Xcode 27.3 beta.
Platform | Beta 1 build |
|---|---|
iOS 27.3 | 24C5037i |
iPadOS 27.3 | 24C5037i |
macOS 27.3 | 26C5035r |
watchOS 27.3 | 24S5284h |
tvOS 27.3 | 24K5286g |
visionOS 27.3 | 24N5286r |
Xcode 27.3 (developer tool) | 27C5020n |
For iOS 27.2, the release candidate (RC) arrived on October 19 and the final version followed one week later on October 26. Once an RC appears, the public release has tended to follow within about a week.
When will iOS 27.3 come out? The .2 to .3 gap
Apple's security releases list gives the public release dates. Here is how long Apple took to go from .2 to .3 in the last two generations.
Generation | .2 released | .3 released | Gap |
|---|---|---|---|
iOS 18 | December 11, 2024 | January 27, 2025 | 47 days |
iOS 26 | December 12, 2025 | February 11, 2026 | 61 days |
iOS 27 | October 26, 2026 | Not yet | 47 days = Dec 12 / 61 days = Dec 26 |
The same yardstick points to mid-to-late December. Keep in mind that iOS 27.2 itself was unusually early: iOS 18.2 and 26.2 shipped 86–88 days after the major release, while 27.2 shipped after 42 days. iOS 27.3 could also come early, or slip past the holidays into January. The reliable signal is the release candidate, so watch for the RC rather than a fixed date.
What changes in iOS 27.3? What Apple has published so far
Apple has not announced consumer-facing features for iOS 27.3. It usually publishes the release notes on About iOS 27 Updates on release day. For now, only the developer-focused "iOS & iPadOS 27.3 Beta Release Notes" are available. The items most likely to reach users are:
Area | Release note | What it means for users |
|---|---|---|
StoreKit (in-app purchases) | Multiseat subscriptions: a customer can buy multiple seats for an auto-renewable subscription and invite others to join it | Apps that adopt it could let one person pay for a family or team plan seat by seat |
Siri AI (known issue) | Siri AI might not request an unlock before showing app data that is set to require unlocking | A known beta issue. Whether it is fixed by release is not stated |
URL filters and Live Caller ID Lookup | Server configuration requirements for developers | No action needed by users |
Features can be added or removed between beta and release, so treat any "iOS 27.3 will add X" claim with caution until the final release notes appear.
Should you install the iOS 27.3 beta?
Through the Apple Beta Software Program, anyone can try pre-release versions and report issues with the Feedback Assistant app. That said:
- Do not install it on your main or work iPhone. Banking or business apps may break until the final release.
- Back up first, and use a secondary device if you can.
- There is little to see in beta 1. Apple has not announced user-facing features yet.
Should you wait for iOS 27.3? Install iOS 27.2 now
If you are still on iOS 27.0.1, update to iOS 27.2 instead of waiting:
- Security: iOS 27.2 fixes more than 160 CVEs. Waiting several weeks for 27.3 means running without those fixes.
- Siri AI languages: iOS 27.2 is the update that expanded Siri AI to Japanese, French, Korean, Portuguese and Spanish.
Apple Watch owners can check what to do when a watchOS 27 update does not show up and how to use Siri AI on Apple Watch.
Which iPhones will get iOS 27.3?
Apple has not published a separate device list for 27.3. As an update within iOS 27, it is expected to cover the same iPhones as iOS 27 (iPhone 11 and later). Siri AI and other Apple Intelligence features remain limited to iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 or later.
Summary
- iOS 27.3 beta 1 arrived on November 3, 2026 (10 a.m. PT). No release date has been announced.
- Based on past .2 to .3 gaps (47 and 61 days), the release is most likely around December 12–26, but this year's schedule has run early.
- Watch for the release candidate. iOS 27.2 shipped one week after its RC.
- No consumer features are announced yet. Developer notes mention multiseat subscriptions.
- If you are on 27.0.1, install iOS 27.2 now rather than waiting.
FAQ
When will iOS 27.3 be released?
As of November 5, 2026, Apple has not announced a release date. The first developer beta was posted on November 3 at 10 a.m. Pacific Time. Applying the gap between the .2 and .3 releases of the last two generations (47 and 61 days) to iOS 27.2 (October 26) points to roughly December 12–26, 2026. This is an estimate, not an Apple announcement, and iOS 27.2 itself shipped about six weeks earlier than past .2 releases.
What is new in iOS 27.3?
Apple has not published consumer-facing features yet. The developer release notes mention support for multiseat auto-renewable subscriptions in StoreKit, where one customer buys several seats and invites others, plus a known issue in how Siri AI handles app data that requires unlocking. Features in a beta can change before the final release.
Should I wait for iOS 27.3 instead of installing iOS 27.2?
No. iOS 27.2 fixes more than 160 CVEs and is the version that brought Siri AI to more languages. iOS 27.3 is likely weeks away, so if you are still on iOS 27.0.1 it is safer to update to 27.2 now.
Can anyone install the iOS 27.3 beta?
Members of the Apple Beta Software Program can try pre-release software and send feedback through the Feedback Assistant app. Beta software is still in development, so avoid installing it on the iPhone you rely on for work and back up first.
