Release notes
What changed
Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.
Release identity
iOS 27 Beta 1 appeared on 2026-06-08. Apple associates build 24A5355q with the seed; the identifier is scoped to iOS even where another platform used the same alphanumeric build.[1]
What changed at this milestone
Apple’s first preserved iOS and iPadOS 27 developer-note state contains 203 itemized entries. This page selects 11 representative initial capabilities and compatibility boundaries; it is a baseline, not a claim that every version-wide preview feature first appeared here.[2]
Channel and device scope
This is a developer beta, not a public release. Apple recommends backing up before installation, reading the exact release notes, and reporting issues through Feedback Assistant.[3]
Evidence boundary
This page cites the human-readable preserved Apple page and uses the matching raw DocC capture only for issue-ID/status comparison. The structured inventory is representative for Beta 1 and delta-based for Beta 2 and Beta 3; no July 17 edit is assigned to the iPadOS revision.[4]
