• Disallow content transition when opening before a popup bar was presented
• Fixed incorrect content view frame calculation in certain conditions (#645)
• UINavigationController layout fixes

Popup bar will now present correctly in minimized state when needed (#643).

• Fixed a legacy Catalyst layout issue

• .automatic is now the default popup interaction style
  • The automatic interaction style uses snap interaction style for opening the popup and drag interaction style for closing
  • Automatic resembles Apple's Music interaction styles and retains all popup content transition support already in place
  • To restore the previous interaction style, set myPopupPresentingController.popupInteractionStyle to .snap
• iOS 27 minimization improvements
• Improved handling of drag/automatic interaction dismiss behavior
• Progress view layout improvements on Mac Catalyst
• Improved automatic popup content transition image discovery to include child controllers

• .automatic is now the default popup interaction style
  • The automatic interaction style uses snap interaction style for opening the popup and drag interaction style for closing
  • Automatic resembles Apple's Music interaction styles and retains all popup content transition support already in place
  • To restore the previous interaction style, set myPopupPresentingController.popupInteractionStyle to .snap
• iOS 27 minimization improvements
• Improved handling of drag/automatic interaction dismiss behavior
• Progress view layout improvements on Mac Catalyst
• Improved automatic popup content transition image discovery to include child controllers

Fixed a crash in iOS 27 beta 5

• Implemented the automatic interaction style

  • The automatic interaction style lets the system handle interactions, and may choose different interaction styles for opening and closing the popup
  • Not yet enabled by default; set popupPresentationContainerController.popupInteractionStyle = .automatic to enable

• Catalyst improvements

• Enabled popupBarAvoidsPrimaryColumn and popupOpensOverSplitViewController by default on all device types
  • To revert to the previous behavior, set them to false on the respective popup presentation container controller
• popupBarAvoidsPrimaryColumn and popupOpensOverSplitViewController are no longer limited to iOS 26 or 27
• Reworked bar and content view close button metrics on iOS 27
  • Bar metrics gated behind inheritsBottomBarMetrics, which is enabled by default
• Some layout improvements
• Fixed compiler warnings for really old iOS versions (iOS 13..<15)

This is a very big release, with many improvements.

• Many layout improvements to the popup bar and how it handles the countless variations of bar buttons
• Fixes to complex RTL layouts
• Catalyst and iPad are now much better supported, with layouts that were previously not possible
  • The LNPopupItem.leadingBarButtonItems and LNPopupItem.trailingBarButtonItems APIs have been undeprecated and it is now possible to place leading and trailing buttons on any bar style
  • The LNPopupItem.barButtonItems will continue to place items at the trailing edge; however, if you were relying on the previous behaviur, where LNPopupItem.leadingBarButtonItems would be placed in the trailing items on floating bars, this is no longer the case
• If too many buttons are placed in a bar item and there is no space for the image and/or titles, the popup bar will hide elements to make space available for buttons
  • This is especially important in freely resizeable environments, such as iPads, Mac windows and … future iPhone devices
  • Use the new LNPopupBar.effectiveContentSize API to inspect the effect size of the popup bar content and reduce the number of buttons depending on available space
• Escape key now closes the popup in most scene environments
  • Some more complex scenes cannot be supported since the popup might be opened in a controller that is not in the responder chain
  • In these cases, route the keys yourself or make the view controller the first responder
• Catalyst now has first-class support and a new example project
• New APIs introduced to better support split view controllers on large devices
  • UISplitViewController.popupBarAvoidsPrimaryColumn API has been introduced to better supprot environments where a popup is presented with the split view controller as the popup presentation controller
    • When enabled, the system will attempt to avoid the primary split and move the popup bar out of the way
    • The popup will continue to open over the entire split view controller’s bounds
    • Enabed by default
  • UIViewController.popupOpensOverSplitViewController API has been introduced to better support environments where a popup is presented by a popup presentation controller that is part of a split view controller scene
    • When enabled, the system will open the popup over the entire split view controller’s view bounds rather than only within the specific split
    • This is enabled by default on Catalyst but disabled on iOS (to preserve previous behavior)
    • The popup bar will remain within the containing view controller’s bounds
  • The two new APIs can result in a similar looking behavior from the user’s standpoint, but offer different benefits and tradeoffs; consider first presenting your popup bar over the split view controller

Continued improvements to layout and transitions
