A SwiftUI popover presented from a button installed in the nav bar via .toolbar(...) does not dismiss when tapped outside the popover. Instead, it jumps to the upper left corner of the screen. This started happening in Xcode 12 beta 6. I've filed a bug with Apple (FB8546290). .toolbar {     Button("Bad Popover") {         isShowingBadPopover.toggle()     }     .popover(isPresented: $isShowingBadPopover) {         Text("Tap outside and notice that the popover moves instead of being dismissed.")             .padding()             .frame(width: 320, height: 100)     } }

I have a UITextView that contains paragraphs with text bullet lists (via NSTextList). I also implement NSTextContentStorageDelegate.textContentStorage(_:, textParagraphWith:) in order to apply some custom attributes to the text without affecting the underlying attributed text. My implementation returns a new NSParagraph that modifies the foreground color of the text. I based this on the example in the WWDC 21 session "Meet Text Kit 2". UITextView stops rendering the bullets when I implement the delegate function and return a custom paragraph. Why? func textContentStorage(_ textContentStorage: NSTextContentStorage, textParagraphWith range: NSRange) -> NSTextParagraph? { guard let originalText = textContentStorage.textStorage?.attributedSubstring(from: range) else { return nil } let updatedText = NSMutableAttributedString(attributedString: originalText) updatedText.addAttribute(.foregroundColor, value: UIColor.green, range: NSRange(location: 0, length: updatedText.length)) let paragraph = NSTextParagraph(attributedString: updatedText) // Verify that the text still contains NSTextList if let paragraphStyle = paragraph.attributedString.attribute(.paragraphStyle, at: 0, effectiveRange: nil) as? NSParagraphStyle { assert(!paragraphStyle.textLists.isEmpty) } else { assertionFailure("Paragraph has lost its text lists") } return paragraph }

I'm using SwiftUI's TextEditor. I'd like to include an undo button in my UI that operates on the TextEditor. I don't see a way to hook this up. You can get the UndoManager from the environment, but this is not the undo manager the TextEditor is using. I know that UITextView uses an undocumented UndoManager (_UITextUndoManager) and I've accessed that before when using a UIViewRepresentable wrapper around UITextView. I'd like to achieve the same with TextEditor.
