iOS 27: Everything We Know Before WWDC 2026
Apple is expected to announce iOS 27 at WWDC 2026, with the keynote imminent. The leak cycle has been unusually active in the weeks leading up to the announcement — more so than for iOS 26 at the same point last year — and the picture emerging from credible sources is clear enough to summarise with reasonable confidence.
Here is what we know, what is reported but unconfirmed, and what to watch for at the keynote.
The Notification Redesign
The most visually significant change reported for iOS 27 is a redesign of how notifications appear on the lock screen and home screen. According to a leak corroborated by multiple sources, notifications in iOS 27 will slide in from the left side of the screen rather than dropping from the top.
The change is more than cosmetic. The new animation is reportedly paired with a revised grouping system that clusters notifications by type and urgency rather than by app and chronological order. Apple Intelligence is said to be involved in the prioritisation layer — meaning the same on-device model that currently powers notification summaries will also influence which notifications are surfaced prominently and which are grouped into a lower-priority cluster.
For readers following the notification redesign in detail, we covered the initial leak when it first surfaced.
Siri: A Queue System for AI Features
One of the more unusual reports concerns a new queuing mechanism for Siri’s AI-powered features. According to reliable Apple journalist sourcing, iOS 27 may introduce a system where users are placed in a queue for access to newer or more computationally intensive Siri capabilities as they roll out.
The rationale, as reported, is infrastructure management — Apple is rolling out more capable on-device and Private Cloud Compute features, and a queue prevents simultaneous demand from degrading the experience for all users during the rollout period.
If accurate, this would represent a meaningful shift in how Apple delivers new features — from a simultaneous release to all supported devices toward a gradual individual rollout. This has implications for how reviewers assess iOS 27 at launch, since two users on identical hardware may have access to different feature sets depending on their queue position.
We reported the initial sourcing on this when it emerged earlier this month.
Compatibility: Four Models Reportedly Dropped
A leaker with a reasonable track record for iOS compatibility information has claimed that iOS 27 will drop support for four iPhone models currently running iOS 26. If accurate, this would leave the following as the minimum supported device for iOS 27: iPhone 12 or iPhone 13, depending on which four models are cut.
Apple has not confirmed this. The claim aligns with Apple’s general pattern of dropping two to four models per iOS generation cycle, but the specific models have not been verified by a second source.
The compatibility cut matters for Apple Intelligence specifically. Apple Intelligence already excludes pre-A17 Pro devices. An iOS 27 compatibility cut that removes pre-A15 devices would further consolidate the supported base around hardware capable of running more advanced on-device AI features.

Apple Intelligence in iOS 27: What Is Expected
iOS 26 shipped Apple Intelligence in a form that was half-finished by Apple’s own implicit roadmap. The expanded Siri — with cross-app actions, conversational context, and screen awareness at full capability — was promised but delivered only in limited form.
The expectation for iOS 27, based on Apple’s stated direction and analyst reporting, is that this gap closes meaningfully. Specifically:
Multi-step cross-app requests. The scenario that Apple demonstrated at WWDC 2024 — “find that photo and send it to the person I was messaging” — should work reliably in iOS 27 where it still frequently fails in iOS 26.
Expanded language support. Apple Intelligence launched US English-first and has expanded across point releases. iOS 27 is expected to bring full feature parity to a larger set of languages, reducing the gap between English and non-English feature sets that has frustrated international users and publications covering the Apple ecosystem in non-English markets.
For readers outside the United States tracking which Apple Intelligence features are available in their language — particularly in German-speaking markets where the rollout lag has been a persistent issue — Apfelpatient documents each iOS release specifically for feature availability in European and English languages. Their iPhone coverage tracks what arrives in each point release for both English and non-English users.
Personal context depth. The ability for Siri to read and act on the full context of your apps — not just messages and emails but documents, third-party apps, and system data — is expected to expand in iOS 27 through deeper developer API access.
What to Watch For at the WWDC Keynote
Based on the leak landscape, these are the three announcements most worth watching at the iOS 27 keynote.
Whether the notification redesign ships as leaked. The left-slide animation has been credibly sourced, but Apple has reversed course on design changes before when internal testing produces negative feedback. Confirmation at WWDC will tell us whether the lock screen is getting its most significant visual change since iOS 16.
The Siri queue announcement. If real, this is a significant policy change in how Apple rolls out software features. The framing at WWDC will reveal whether it is presented as a feature (personalised rollout) or a limitation (capacity management).
The compatibility cut confirmation. Which models get cut from iOS 27 will clarify whether Apple is accelerating the push toward a smaller, more capable supported device base — which would be consistent with the Apple Intelligence hardware strategy.

Timing
iOS 27 will be announced at WWDC 2026 and is expected to enter public beta shortly after. General release follows in September 2026 alongside the iPhone 17 lineup. Developer betas typically reveal the full feature set within the first two releases — which means the picture will be substantially clearer within days of the keynote.
FAQ
When will iOS 27 be released? iOS 27 is expected to be announced at WWDC in June 2026 with a public release in September 2026 alongside new iPhone hardware.
Which iPhones will support iOS 27? Not confirmed. A leak suggests four models will be dropped from iOS 26 support, but the specific models have not been verified by a second source. Historically, Apple announces compatibility alongside the iOS announcement at WWDC.
Will iOS 27 improve Apple Intelligence significantly? Analyst expectations and sourcing point to meaningful improvements in Siri’s cross-app action capability and expanded language support. Whether these improvements match Apple’s original roadmap presentation remains to be confirmed at WWDC.
Will iOS 27 be a major or minor update? One journalist with strong Apple sourcing has described iOS 28 as “far more significant” than iOS 27 — implying iOS 27 is a meaningful but not transformational release. iOS 27 appears to close gaps left by iOS 26 rather than introduce a new category of features.
Will the notification redesign change how Apple Intelligence handles notifications? Likely yes, based on reporting that the new notification grouping system involves on-device AI prioritisation. The details will depend on WWDC confirmation.
