The first two requirements may hint at an upcoming iPhone Fold device. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What do I need to change in my app to support iOS 27? Apps must satisfy three requirements to deploy on iOS 27. The app delegate must be removed since the UI scene life cycle is now mandatory, a proper launch screen must be provided instead of a pre-rendered image, and the app must support the liquid glass look, which can no longer be opted out of. _daily.dev helps developers track iOS platform requirement changes before they hit production._ ### Is the app delegate still supported in iOS 27? No, the app delegate approach is being phased out because the UI scene life cycle has become mandatory for apps deploying on iOS 27. Developers relying on the older app delegate lifecycle will need to migrate to the scene-based lifecycle to remain deployable. _Teams migrating legacy iOS lifecycle code can follow platform changes like this on daily.dev._ ### Can I opt out of liquid glass design in iOS 27? No, supporting liquid glass is required and it is no longer possible to opt out of the new look and feel when deploying to iOS 27. This is one of three mandatory requirements alongside removing the app delegate and providing a proper launch screen. _daily.dev keeps developers updated on mandatory design shifts like liquid glass adoption._ ## Similar posts on daily.dev - [Issue \#83: Liquid Glass goes mandatory, Foundation Models opens up, and non-modal panels in SwiftUI](https://daily.dev/posts/issue-83-liquid-glass-goes-mandatory-foundation-models-opens-up-and-non-modal-panels-in-swiftui-3iaih8wgv) · iOS Code Review · 0 upvotes · 0 comments --- Tags: [#mobile](https://daily.dev/tags/mobile), [#ios](https://daily.dev/tags/ios), [#swift](https://daily.dev/tags/swift) [View this post on daily.dev](https://daily.dev/posts/deploying-to-ios-27-here-are-the-3-major-requirements--rtw7k2wt1) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Deploying to iOS 27: Here are the 3 Major Requirements.","url":"https://daily.dev/posts/deploying-to-ios-27-here-are-the-3-major-requirements--rtw7k2wt1","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/deploying-to-ios-27-here-are-the-3-major-requirements--rtw7k2wt1"},"datePublished":"2026-07-09T09:09:58.609Z","dateModified":"2026-09-14T09:03:37.888Z","description":"iOS 27 introduces three mandatory requirements for app deployment: the UI scene lifecycle replaces the app delegate (making it mandatory), apps must provide a...","image":"https://i.ytimg.com/vi/KaQGHYkKlw8/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/KaQGHYkKlw8/sddefault.jpg","isAccessibleForFree":true,"articleSection":"Vincent Pradeilles","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Vincent Pradeilles","logo":"https://media.daily.dev/image/upload/s--f_OeYCEF--/f_auto/v1721999625/logos/vpradeilles","url":"https://daily.dev/sources/vpradeilles"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/deploying-to-ios-27-here-are-the-3-major-requirements--rtw7k2wt1","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"mobile,ios,swift","timeRequired":"PT1M","video":{"@type":"VideoObject","name":"Deploying to iOS 27: Here are the 3 Major Requirements.","description":"iOS 27 introduces three mandatory requirements for app deployment: the UI scene lifecycle replaces the app delegate (making it mandatory), apps must provide a...","thumbnailUrl":"https://i.ytimg.com/vi/KaQGHYkKlw8/sddefault.jpg","uploadDate":"2026-07-09T09:09:58.609Z","duration":"PT1M","url":"https://api.daily.dev/r/rtw7K2wt1","embedUrl":"https://www.youtube.com/embed/KaQGHYkKlw8"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Vincent Pradeilles","item":"https://daily.dev/sources/vpradeilles"},{"@type":"ListItem","position":3,"name":"Deploying to iOS 27: Here are the 3 Major Requirements."}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/deploying-to-ios-27-here-are-the-3-major-requirements--rtw7k2wt1#faq","mainEntity":[{"@type":"Question","name":"What do I need to change in my app to support iOS 27?","acceptedAnswer":{"@type":"Answer","text":"Apps must satisfy three requirements to deploy on iOS 27.
