Alternate calendars

Bidirectional text
See also: Get it right to left
Bidirectional text is when left-to-right and right-to-left language words are combined in one text
This has significant implications for text selection
Characters are always stored in the order they are written, only display varys
When selecting bidirectional text, the cursor used to “jump”, creating a confusing experience
New in iOS 26, selection in UI is now intuitive, the storage is adjusted accordingly


To adopt this, instead of a single selected range, an array of selected ranges is required
On macOS, this was already possible –
NSTextViewhadselectedRangesBut on iOS,
UITextViewhad onlyselectedRangewhich will be deprecated in favor ofselectedRangesLearn more: Codealong Cook up a rich text experience in SwiftUI with AttributedString
New versions of edit menu
UITextViewDelegateandUITextFieldDelegatemethods availableUse TextKit 2 to utilize
textView.textLayoutManager(instead oftextView.layoutManager)Writing direction used to be different from text direction in bidirectional text, leading to cursor “stay in place”
This year, when switching from LTR to RTL, the cursor moves naturally considering it to be an LTR sentence
Writing direction will now be dynamically determined for whole sentence based on text content
