https://developer.apple.com/documentation/xcodekit/creating_a_source_editor_extension I created new MacOS project and added a Xcode Source Editor Extension target to the project. I run the extension in debug mode with extension target, but the extension is not show up in Editor menu debug mode Xcode. Xcode version is 15.3(released) MacOS version is 14.4.1 Sonoma

Env: any iOS 15.0+ devices. I installed the thirtd-party keyboard app like Gboard, Naver SmartBoard, SwiftKey etc. And, I added the keyboard app from Settings -> General -> Keyboard -> Keyboards -> add new keyboard... However, the third-party keyboard is not shown in safari, finder, but shown in Notes app or the other apps. I remove the third-party keyboard app from Settings -> ... -> Keyboards and if I add it repeatedly, it is shown. I think this is a bug of iOS 15. I don't have expreience in iOS 13, iOS 14.

Using iOS keyboard extension, I want to move the caret to first of strings in textfield. So, I try to get the string before cursor, and move cursor. The offset is the text length, like below. The textfield's text in safari(apple.com search field) is "abcd". But, the return value is " abcd" including space character at first. So, the cursor does not move because the length(length 5) is exceeded the real text length(length 4). This is definitely appeared independently of iOS versions. guard let text = textDocumentProxy.documentContextBeforeInput else {       return     }           print("text(\(text)) = \(text.count)")           textDocumentProxy.adjustTextPosition(byCharacterOffset: -text.count)
