Apple’s WWDC 2026 keynote kicks off today at 10 a.m. PT, and right after it wraps, iOS 27 Developer Beta 1 should be live. I wrote up a full WWDC 2026 preview yesterday with the broader context. This piece is the practical beta breakdown.
Here’s everything I know going into today’s beta release, based on reporting from Bloomberg’s Mark Gurman, MacRumors, 9to5Mac, Macworld, and Apple’s own official announcements.
The Snow Leopard Thing Is Real
Bloomberg reported way back in November 2025 that Apple was framing iOS 27 internally like Mac OS X 10.6 Snow Leopard. That release was famous for shipping almost no visible new features while rewriting huge chunks of the OS under the hood. iOS 27 isn’t going that far, but the philosophy is the same: fix the foundation before adding more surface area.
In practice that means better battery life, smoother animations, fewer bugs, and a general tightness iOS has been missing since the Apple Intelligence rollout added a lot of moving parts. If you’ve been on the developer beta train before, you know Beta 1 is usually the roughest ride. Apple’s bet is that by focusing on stability, this year’s Beta 1 will be more usable than previous cycles.
The Siri Overhaul (This Is the Big One)
iOS 27 ships the most significant Siri redesign since the feature launched. This has been rumored for years, delayed multiple times, and is finally landing — powered by Google’s Gemini under the hood, with Apple’s privacy layer on top. I covered the full Siri / Gemini backstory here when the Apple-Google deal became public.
Standalone Siri app. Think ChatGPT’s interface: a grid of past conversations, the ability to upload files and photos, auto-deleting conversations after 30 days. It’s a chat app, full stop.
The “Search or Ask” panel. Swipe down from the center of the Dynamic Island and you get a search-and-ask interface that replaces the old Siri card. It’s dark-toned and voice-first, but you can type too.
Conversation memory. Siri can remember what you talked about earlier in the same session, which is something the old Siri fundamentally couldn’t do. This makes complex multi-step requests actually work.
Proactive suggestions. Calendar knows you have an airport pickup scheduled and suggests you leave early to beat traffic. It’s contextual, not annoying.
New Writing Tools. A Grammarly-like grammar check that lives in a translucent slide-up menu. A “Write with Siri” toggle on the keyboard. A “Help Me Write” button. It’s Apple’s answer to the AI writing assistant race, and it’s baked into the system at the keyboard level.
One caveat: 9to5Mac reports some of these Siri features may require joining a waitlist. That’s classic Apple — roll out the infrastructure first, flip the switch when they’re confident in the capacity. The company has also been planning to open Siri to third-party AI services, so this infrastructure buildout is going to matter beyond just the Gemini deal.
Apple Intelligence Gets Real Features
iOS 26 shipped Apple Intelligence as a headline feature, but a lot of the good stuff was “coming later.” iOS 27 actually delivers it.
AI web search. A Perplexity-style search tool that queries the web and summarizes results. It’s built into Siri and Spotlight.
Photos gets the treatment you’ve been waiting for. “Extend” generates content beyond the original frame (like what Google Photos has been doing). “Enhance” auto-adjusts lighting, color, and quality. “Reframe” shifts perspective for spatial photos. The Clean Up tool also got a serious upgrade.
AI-generated custom wallpapers. Image Playground expands into wallpapers, so you can describe what you want and iOS generates it. This is going to be the feature everyone shows their friends.
Natural language Shortcuts. Instead of digging through the Shortcuts app’s maze of triggers and actions, you can describe what you want and iOS builds the shortcut. Long overdue.
Generated Subtitles for any video. Apple officially confirmed this in its May 19 accessibility announcement: on-device generated subtitles for personal and uncaptioned videos across iPhone, iPad, Mac, Apple TV, and Vision Pro. English (U.S. and Canada) at launch.
The Camera App Is Finally Customizable
Apple’s Camera app has had the same basic layout for years. iOS 27 tears it up.
You can now pick which camera controls appear and where using an “Add Widgets” system. Three categories: Basic, Manual, and Settings. Want depth of field on the main screen but don’t want timer controls cluttering things up? You can set that. Exposure, photo styles, and other controls can be arranged however you want.
There’s also a new “Siri” mode in the Camera app that gives you quick access to Visual Intelligence — point it at a nutrition label or a QR code or a contact info card and it reads the data back to you. It’s basically what Google Lens has been doing for years, but it’s finally native in iOS.
iPhone Fold Gets Its First iOS Preview
This is the quiet section, but it’s probably the most important feature for what Apple has coming hardware-wise. iOS 27 includes optimizations for the rumored foldable iPhone, which Bloomberg says is launching in September 2026 with a ~7.8-inch inner display and ~5.5-inch outer display.
The headline feature: side-by-side split view. Two apps running simultaneously on the same screen. This is a first for iPhone. Apple has rebuilt its own apps with foldable-friendly layouts, and there’s a developer API for third-party apps to do the same.
If you don’t have a foldable iPhone (which is basically everyone right now), you won’t see these features yet. But they’re in the OS, waiting for the hardware.
Everything Else Worth Mentioning
Apple Wallet — “Create a Pass” lets you convert physical passes (gym membership, library card, whatever) to digital passes by snapping a photo. Apple Cash gets bill splitting: photo a receipt, assign items to people, send payment requests. U.S. only.
Calendar — Major redesign. The one Apple has been working on for two years and kept delaying. It’s finally here.
Notifications — They slide in from the left now instead of dropping from the top. Subtle visual change, but it changes the whole feel of the lock screen.
Satellite features — Apple Maps via satellite. Messages photo sending via satellite. New modem hardware enables it.
Safari — New start page with four tabs: Favorites, Bookmarks, Reading List, History. Smarter tab grouping that actually learns your patterns.
Weather — New “Conditions” panel on each city page showing rain, wind, and other data at a glance.
AirPods — Redesigned interface in Settings. New pairing system that’s supposed to be faster and more reliable.
Find My — Visual refresh. New tab bar icons. Nothing dramatic.
Autocorrect — Improved. Bloomberg says this is a real upgrade, not a placebo.
Keyboard — New activation animation. Undo and redo controls for home screen customization.
AirPlay — Possible Google Cast support. Likely EU-only thanks to the DMA.
Which iPhones Support iOS 27 (and Which Don’t)
Apple is dropping four devices this year:
- iPhone 11
- iPhone 11 Pro
- iPhone 11 Pro Max
- iPhone SE (2nd generation, 2020)
If you have an iPhone 11 or the 2020 SE, iOS 26 was your last major update. That’s a seven-year run for the 11 series, which is honestly a good run by any standard.
Everything from the iPhone 12 line and newer is supported, including the iPhone SE 3 (2022), iPhone 16e, and the iPhone Air. Full list:
- iPhone 17 / 17 Pro / 17 Pro Max (2025)
- iPhone Air (2025)
- iPhone 16e (2025)
- iPhone 16 / 16 Plus / 16 Pro / 16 Pro Max (2024)
- iPhone 15 / 15 Plus / 15 Pro / 15 Pro Max (2023)
- iPhone 14 / 14 Plus / 14 Pro / 14 Pro Max (2022)
- iPhone SE 3 (2022)
- iPhone 13 / 13 mini / 13 Pro / 13 Pro Max (2021)
- iPhone 12 / 12 mini / 12 Pro / 12 Pro Max (2020)
One important note: Apple Intelligence still requires an iPhone 15 Pro or newer. If you’re on an iPhone 15 or earlier, you’ll get iOS 27’s performance and stability improvements, but the AI features stay locked to the Pro models and the 16/17 series.
How to Install the iOS 27 Developer Beta
Good news: you don’t need the $99/year Apple Developer Program. A free Apple Developer account is enough. Here’s the process once the beta goes live:
- Sign in at developer.apple.com with your Apple Account.
- Restart your iPhone.
- Go to Settings > General > Software Update > Beta Updates.
- Select “iOS 27 Developer Beta.”
- The update should appear. Download and install.
Back up your iPhone first. This isn’t optional. Beta 1 is going to have bugs. Make sure you can roll back if something breaks.
The Public Beta will follow in July through beta.apple.com. If you’re not on a developer account, that’s your path. (Last year’s iOS 26 Public Beta guide is still a good reference for what to expect.)
Should You Install Beta 1?
It depends on your tolerance for bugs.
If you have a backup device or a secondary iPhone you use for testing? Go for it. The Snow Leopard focus means this Beta 1 might actually be more stable than previous years, but it’s still Beta 1. Things will break. (Last year’s iOS 26 Beta 1 had a stealth build update a week in to fix bugs — expect similar this time around.)
If this is your daily driver and you need your phone to work? Wait for the Public Beta in July, or at least until Beta 2 or 3. The early developer betas are for developers, not for everyone. Apple means that.
The Bottom Line
iOS 27 is the year Apple fixes what it shipped and finally admits it can’t build a competitive large language model on its own. The Gemini partnership for Siri is the biggest strategic shift Apple has made in AI since it launched Siri in the first place. The Snow Leopard framing isn’t marketing spin — it’s a recognition that iOS 26’s Apple Intelligence rollout was rushed and the OS needed breathing room.
For most people, the practical takeaway is simple: iOS 27 will make your phone run better, your Siri will finally be useful, and in September the foldable iPhone will arrive with software that’s ready for it. Not bad for a “stability release.”
