iOS 28 Release Date: When Is It Coming Out?

The announcement: why June 7, 2027

Apple doesn't announce iOS versions on a whim — it announces them at the WWDC keynote, and the WWDC keynote lands on a Monday in the first full week of June with near-perfect regularity. That single pattern is the anchor for every other date on this page.

In 2027, the first full week of June begins Monday, June 7. Barring something unprecedented, that's keynote day: a roughly two-hour presentation starting 10:00 a.m. Pacific, with iOS 28 as the headline act, followed by iPadOS 28, macOS, watchOS, and the rest of the platform family. The first developer beta historically goes live within hours of the keynote ending.

What time does iOS 28 come out?

This is the single most-searched question on release day, and Apple has been remarkably consistent about the answer: 10:00 a.m. Pacific. That's the same slot the WWDC keynote itself starts in, and it's the window Apple has used to flip on both the June beta and the September final release, year after year.

The mechanism is simple. Apple activates the update from its own servers for everyone at once, and that activation has landed in the same Pacific-morning window release after release. If you're counting down to install day, set your alarm for the Pacific morning, not for midnight in your own time zone.

A decade of receipts: Apple's actual release history

Projections are only as good as the pattern behind them. Here is Apple's real announcement-to-release record:

Two things stand out. First, the keynote has stayed inside a five-day window of early June for over a decade. Second, the final release lands in the third week of September like clockwork, tied to the new iPhone going on sale. (And if the version numbers look odd: Apple jumped from iOS 18 to iOS 26 in 2025, renaming its platforms after the year ahead — which is exactly why 2027's release is iOS 28.)

Why we can project this at all

None of the dates on this page come from a leak, a source inside Apple, or anything other than the public record above. They come from pattern-matching Apple's own decade-plus of behavior — the same way you'd predict a train's next arrival from its timetable, not from asking the conductor.

Two patterns are unusually strong. The WWDC keynote has landed on the Monday of the first full week of June for more than ten consecutive years, missing that window only rarely. The final release has landed in mid-September, days after Apple's iPhone event, with equal consistency going back just as far. When two independent patterns are both that stable for that long, projecting the next occurrence forward is a reasonable inference — not a guarantee.

What this page is not doing: claiming insider knowledge, naming anonymous sources, or asserting these dates as confirmed. Every date above is labeled as a projection until Apple says otherwise, and we update it within minutes of any official confirmation.

The full iOS 28 beta schedule, projected

Between the keynote and September, Apple runs a public rehearsal with a predictable rhythm — roughly a new build every two weeks, accelerating to weekly near the end:

How the beta cycle actually unfolds, week by week

The table above gives you the projected dates. Here's what actually happens in each of those windows, based on how every iOS beta cycle from iOS 16 through iOS 27 has played out.

Week 0 — keynote day (beta 1). This is the roughest build of the cycle by a wide margin. Expect new bugs, occasional app crashes, batteries that drain faster than usual, and features that are visibly unfinished or entirely absent — Apple often ships beta 1 with some announced features not yet included at all. This build is for developers testing their apps, not for anyone who needs their phone to work reliably.

Weeks 2–3 — beta 2. The first real stability pass. Apple patches the most disruptive bugs from beta 1 and starts filling in features that were missing on day one. Still developer-only, still risky for a primary device.

Weeks 4–5 — beta 3 and the public beta. This is usually the point where Apple opens registration to everyone through beta.apple.com, running in step with developer beta 3. It's the build most people mean when they say "I installed the beta" — noticeably calmer than beta 1, though still capable of odd bugs, and still not something to put on a phone you can't afford to have misbehave for a day.

Weeks 6–11 — betas 4 through 8, through August. Each build tightens further. By the later betas in this stretch, most day-to-day quirks are ironed out and the update starts to feel close to what will ship. This is the safest window to try the beta if you're going to at all — most major bugs are behind you, but you still get weeks of runway before the final release.

Early September — the Release Candidate. Typically arrives the same week as Apple's iPhone event. The RC is, functionally, the final build — barring a last-minute critical bug, whatever ships as the RC is what everyone gets a few days later. If you've been avoiding the beta all summer, the RC is the lowest-risk moment to jump on.

Mid-September — final release. iOS 28.0 goes out to everyone, typically a few days after new iPhones go on sale so they ship with it out of the box.

What could move these dates

The honest error bars on our projection:

• The keynote date (±1 week). Apple occasionally slides to the second week of June — iOS 18 was announced June 10. June 7 is the best single guess, not a certainty. Apple typically confirms WWDC dates in March or April.
• Staggered features (high likelihood). Recent history says the September "release" is really the start of a rolling launch — headline features, especially Siri and Apple Intelligence upgrades, increasingly arrive in the .1 and .2 updates through spring. Expect some of the biggest iOS 28 features to follow that pattern.
• The release week (±1 week). The final build tracks the iPhone launch. If the iPhone 19 event shifts, iOS 28.0 shifts with it.

What history says about slips and surprises

A fair projection also has to account for the times Apple's own pattern hasn't held perfectly. It happens — just less often, and in smaller ways, than most people assume.

Features slip past launch day more often than dates do. Apple has repeatedly announced a headline feature at WWDC in June and then shipped it later — sometimes weeks later, in a .1 or .2 point update, rather than in the version's initial release. Recent Apple Intelligence rollouts are the clearest example: several capabilities shown at the keynote arrived in stages across the point updates that followed the initial release, not all at once on day one.

Features have also been pulled outright. Apple announced a planned iCloud Photos scanning feature in 2021 and, after public pushback, indefinitely postponed it before it ever shipped. It's a reminder that "announced" isn't the same as "guaranteed," even for features that make it all the way to a public unveiling.

The release date itself has moved — but only by days, not weeks. In most years, the gap between the keynote and the final release has landed within a few days of the prior year's gap. Occasional single-digit-day drift is normal; a multi-week slip in the final release date has not happened in the modern WWDC era.

Put together, the realistic "worst case" for iOS 28 isn't a late release. It's a normal-timed release where a few of the features you saw demoed on June 7 aren't actually in your hands until an update or two later. Keep that distinction in mind when you're reading any iOS 28 feature list — the date is the stable part; the feature set is the part that moves.

What to do between now and June 7, 2027

• Check your hardware. If your iPhone is on the expected support bubble — looking at you, iPhone 12 owners — factor that into any upgrade you're planning anyway.
• Enroll early. Both developer.apple.com and beta.apple.com enrollment can be done today; it carries over to iOS 28 automatically.
• Bookmark this page. It is updated within minutes of Apple making anything official — WWDC dates, beta drops, and the final release.
