iOS 27 introduces enhanced iCloud capabilities across various Apple applications, including Home, Siri, and Photos. HomeKit Secure Video cameras benefit from Apple Intelligence features within the Home app, offering text summaries of events and improved video playback timelines. These advanced HomeKit features require a 2TB or greater iCloud+ plan, which also allows for an unlimited number of HomeKit Secure Video cameras. Daily usage limits for some Apple Intelligence features, such as Image Playground, can be increased with most iCloud+ plans. Siri conversations are now synced via iCloud across devices, enabling users to revisit and continue chats. The Photos app sees several iCloud improvements, including a prioritize syncing toggle, cross-platform uploads to Shared Albums, and faster initial uploads. iCloud collaboration links provide richer previews and easier access requests, with faster access to shared content on iCloud.com. Journal entries will now display their iCloud sync status. The Passwords app can leverage Apple Intelligence to automatically fix weak passwords, utilizing iCloud Keychain and Safari. To use these Apple Intelligence features, a compatible iPhone and in some cases, a home hub, are necessary.
