iOS 27 is Here. So is Day-Zero Support on Real Devices.

Apple shipped iOS 27, and Sauce Labs customers can start testing against it today — on real devices, no waitlist.

What's new in iOS 27

iOS 27 brings changes substantial enough to force nearly every iOS team into a testing cycle:

• New app lifecycle model. The scene-based (UIScene) lifecycle is now mandatory. Apps built with the iOS 27 SDK that still rely on the legacy app delegate model will fail to launch.
• Redesigned UIKit components. Standard system components ship with new layouts — the search scope bar, for example, now sits inline with the search field. Your screens can visually shift with zero code changes on your end.
• Siri AI and App Intents domains. Apps that adopt App Intents schemas matching a built-in domain become directly queryable and actionable through Siri AI's natural-language interface, with no custom training required.

Why day zero matters

Every customer with an iOS app is facing this testing cycle whether they're ready or not. Wait until issues surface in production, and the fallout moves past an engineering fire drill into App Store ratings and complaints from users who've already had the bad experience. Testing on real iOS 27 hardware now, before the update reaches your users, is how you catch lifecycle crashes, UI regressions, and layout shifts while you still have the runway to fix them.

• Test for real-world conditions: Confirm performance, responsiveness, and hardware interactions on real iOS 27 devices before your users upgrade.
• De-risk every release: Catch UI regressions and behavior changes from Apple's updated frameworks before they reach production.
• Keep your release cycle intact: Mitigating issues now means smoother releases, faster development cycles, and a clear competitive edge.

Coverage isn't just a device count

The real test for a release team is simpler: Can I test what I need to test at the moment I need to test it?

Sauce Labs gives you 10,000+ real Android and iOS devices across 3,000+ OS and browser combinations — from brand-new releases like iOS 27 down to the versions your enterprise users are still running. But the count is the least interesting part of the story. What actually determines whether coverage protects a release:

• Speed to new OS support. Sauce Labs supports iOS 27 on the day Apple ships it.
• Depth once something breaks. A framework-agnostic platform, paired with real diagnostics depth (video, logs, network conditions), means faster root-cause analysis.
• Public and private, together. Broad on-demand devices for everyday coverage, plus dedicated private pools for release-critical testing.
• Real and virtual, on one platform. Virtual devices give you scale and cost efficiency for early testing, while real devices give you the fidelity your release depends on. You don't need two vendors to get both.

Getting started

If you're new to Sauce Labs, check supported OSes and devices for the full breadth of coverage, and start a free trial to get instant access to real iOS 27 devices.

For existing Sauce Labs customers: check the Platform Configurator for the full list of supported iOS 27 devices, and update platformVersion in your test configuration to start automated testing.
