Revolution in iOS 11 User Interface

Apple is synonymous with App design and User Experience. Apple designing team echelon for design. With the unveiling of iOS 11, Apple reimagined the design of Apps. Well, It’s not quite so big a change as the iOS 7 update, iOS 11 introduces a variety of major changes to the way Apps look and feel. It’s reversing iOS 7 changes. iOS 11 design seems BIG & BOLD, as Apple App Store, Music, and News were among the first to adopt big titles, rounded card-like UI, and filled buttons.

Comprehensive look of iOS 11

- Large Navigation Bar

Big text navigation Bar, Apple almost all default apps appear with the large Navigation bar, for example, Apple Music, App Store, News, Notes, Mail, and much more.
The user experience of Bar is simple and amazing. A large navigation bar design is the notion of ‘Thumb Zone’. Navigation Bar hard-to-reach area in the flow of the thumb zone.

Navigation Bar shrinks when the user scrolls and bouncing back on the pull-down.


  • The developer can control Which UIViewController has a large title and which should have small.
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .automatic //(.always | .never)
  • The developer can embed search control with the navigation bar, that will hide on the scroll and also you can also make search bar static on scroll also.
navigationItem.searchController = UISearchController(searchResultsController: nil)
navigationItem.hidesSearchBarWhenScrolling = false

- Screen Edges Deferring

Many times users find the problem with Notification Center and Control Center conflicted with other apps or sometimes users find the small arrow. Finally, Apple resolved these issues in iOS 11.


  • A new method for UIViewController called preferredScreenEdgesDeferringSystemGestures(), which allows specifying edge should delay gesture for Notification Center and Control Center.
override func preferredScreenEdgesDeferringSystemGestures() -> UIRectEdge {
return .top

Apple also made noticeable UI changes in the OS. You can see a quick comparison of iOS 11: UI Design changes here:
