I am typing string text on textDocumentProxy in a custom keyboard app. The input text includes newlines and punctuation letters, but when I try to edit the textDocumentProxy field, the textDocumentProxy.documentContextBeforeInput in case a newline \n is included, it does not return full content before input. I placed the cursor on after the good morning word center, I got only good string text. The remaining "hi folks", words do not return. Here are some examples I have tried. var inputText = "Hi folks, Good morning to everyone " var txtBeforeCursor = textDocumentProxy.documentContextBeforeInput ?? "" print("Before Cursor text : ",txtBeforeCursor) Output is: Before Cursor text : Good
