Modernizing Your UI for iOS 13

• Deprecation of LaunchImages use Launch Storyboards instead

• New App Store Requirement Any app linking to iOS 13 must ensure correct layout at any size

• Split Screen Multitasking is strongly recommended for iPad Apps

  • Apple is going to expect that most of the applications, unless you want to provide a truly immersive experience, are going to support split screen multitasking

• UINavigationBarAppearance customize .standardAppearance (iPhone portrait), .compactAppearance (iPhone landscape), .scrollEdgeAppearance (if attached to scrollView and scrolled to top, bar uses this one)

  • settable per navigationItem so customization per view controller possible (including color, transparency, …)

let appearance = navigationBar.standardAppearance.copy()
/* configuration */
navigationItem.standardAppearance = appearance

• UIBarButtonAppearance, UIToolBarAppearance

• UITabBarAppearance customize .stackedLayoutAppearance (text below icon), .inlineLayoutAppearance (text right to icon; iPads), .compactInlineLayoutAppearance (text right to icon; landscape; smaller phones)

• UIModalPresentationStyle.[automatic | formSheet | pageSheet] are able to stack behind each other

  • .automatic is the new default; gets resolved at presentation time

  • get the old behavior by viewController.modalPresentationStyle = .fullScreen

  • sheets get gesture recognizer added automatically to support pull-to-dismiss - opt-out possible (see link in description for example project)

  • Appearance Callbacks Not Called for .PageSheet and .FormSheet on presentingViewController: viewWillAppear, viewDisappear, viewWillDisappear, viewDidDisappear

• Search UI

  • offers possibility to hide cancel button and scope control

  • expose UISearchTextField on UISearchBar so customization becomes possible

  • Search Tokens that represent complex searches

    • are copy&pastable and support drag&drop

    • can be created by user/developer from selected text in UISearchTextField

• UITextInteraction the new & easy way to control selection UI

• Multi Selection in Table-/Collection Views simply by Two-Finger-Swipe

  • opt-in by implementing only 1 new delegate method for Tables and Collections

• New Editing Gestures

  • pinch 3 fingers in: copy selected text

  • pinch 3 fingers out paste copied text

  • 3 finger tap || 3 finger swipe back undo

  • 3 finger swipe forward redo

  • opt out by responder.editingInteractionConfiguration = .none

• UIContextMenuInteraction context menus with rich preview, nested menus, in-line sections

  • transform to context menus on macOS

  • UIMenu & UIInteraction provide hierarchical menu construction system

  • adopt by view.addInteraction(UIContextMenuInteraction(delegate: self))

  • customize how view and menu will be presented: UITargetedPreview & UITargetedDragPreview

  • convenience delegate methods for context menus on UITableView & UICollectionView

  • UIViewControllerPreviewing (peek & pop) is deprecated for sake of this new API

  • replace long-press driven behavior/menus by this new API
