The system no longer ignores fixed and flexible spaces when UIBarButtonItems are automatically converted to the window toolbar in the Mac idiom. However, the width specified via fixedSpaceItem(ofWidth: ) is ignored.
- macOS now supports the Apple Sparse Image Format (ASIF). See VZDiskImageStorageDeviceAttachment.
- Interpolating non-localized types into a LocalizedStringResource/String(localized: )/AttributedString(localized: ) value will now display a deprecation warning instead of potentially falling back to a fully-unlocalized string.

- NSTextView supports sound files, such as QuickTime Audio, attached via NSTextAttachment, by utilizing AVPlayer for playback inline.
- There is a new option for the Transaction.Offer.PaymentMode API called oneTime. This new case supports the method of payment for In-App Purchase offer codes.
- Subscription promotional offers can now be signed using JWS and attached to a purchase using the new PurchaseOption.promotionalOffer(_:compactJWS: ) API. There are also new corresponding SwiftUI APIs in StoreKit to attach a signed promotional offer or a signed introductory offer override to a view.
- An animated SwiftUI.Transaction that changes a Window‘s size animates the window’s frame, alongside the frame of the hosting view.
- You can now use View/findNavigator(isPresented: ), View/findDisabled(_: ), and View/replaceDisabled(_: ) to control the presentation of the Find Bar in TextEditor on macOS 26.
- ControlSize now conforms to Comparable, and View/controlSize(_: ) can now be used to clamp the environment’s controlSize to a given range.
- In apps built with the macOS 26 SDK, Section footers within a Form of the GroupedFormStyle now have leading alignment, default font, and foreground styles. Use the sectionActions(content: ) view modifier on your Section to supply section actions, which maintain a trailing placement in macOS.
- Text, TextEditor, and TextField now by default use string contents to determine the appropriate base writing direction for each paragraph, instead of relying on layout directionality. To specify the writing direction explicitly on a per-paragraph basis, use Foundation’s AttributedString.writingDirection attribute. To make the base writing direction follow the layout direction for an entire view, apply the view modifier .writingDirection(strategy: .layoutBased).
- In apps built with the macOS 26 SDKs, a Picker view of a style that produces a button-like control now has a fitted sizing behavior by default. If needed, use the buttonSizing(_: ) view modifier to make the Picker flexible and fill the available width of its container.
- The default label style for macOS menu content is now .titleAndIcon.
- The implementation of some macOS buttons no longer uses NSButton.
- When linking news SDKs, NavigationLinks produce a single view, rather than a list of views in view list contexts. This change improves performance of many NavigationLinks in lazy containers like List. However, if you are relying on ContainerValues propagating out of the label view of a NavigationLink, or similarly relying on ContainerValues of a ButtonStyle used to style a link, the containerValue(_: ,_: ) modifier should be moved outside of the link.
- List no longer ignores the vertical insets of rows with a height close to the default minimum height on iOS and visionOS. Use listRowInsets(_: _: ) to change the vertical row insets.
- In NavigationSplitView and TabViews configured as sidebarAdaptable, the view trailing the sidebar’s safe area is inset in the width of the sidebar. It can display content outside its safe area, underneath the sidebar.
- A Form of the .grouped style now has a more compact appearance when placed within a sidebar or inspector.
- Reuse existing AppKit gesture recognizers in SwiftUI using NSGestureRecognizerRepresentable, and refer to them by name using name.
- After linking new SDKs, the style of search fields with SearchFieldPlacement.sidebar is now fixed to the toolbar. Previously the search field would scroll as the first element in the list.
- In apps that adopt the new design, the buttonBorderShape(_: ) view modifier can be used to customize the shape of bordered buttons. Previously this modifier only affected buttons in Widgets in macOS.
- The buttonSizing(_: ) view modifier specifies the sizing behavior of Button, Picker, Menu, and other button-producing controls. If you are using Spacer views or an infinite-width frame in your Button label to create a flexible button, apply buttonSizing(.flexible) to the Button instead.
- In macOS apps that adopt the new design, buttons of the .bordered style can be tinted with the tint(_: ) view modifier.
- A new property, includesTextListMarkers, is introduced to NSTextList, NSTextContentStorage, and NSWritingToolsCoordinator. This property controls whether to include the text list marker string in the contents of NSAttributedString for paragraphs associated with NSTextList. TextKit 1 expects the marker string, while TextKit 2 does not. AppKit is adopting the TextKit 2 text list behavior starting with macOS 26.
- In TextKit 2, the includesTextListMarkers property has been introduced to NSTextList, NSTextContentStorage and NSWritingToolsCoordinator. For paragraphs associated with NSTextList, the property controls whether to include the text list marker string in the NSAttributedString contents. The classes within TextKit 1 expect the marker string, while the classes within TextKit 2 do not.
