I create a tool XLLoger, that can redirect stdout to the textView, It works well on iOS14 and below, but on iOS15, when the app running on Xcode connecting the device or simulator, the code can get the logs, if disconnected xcode, the app can't get print log, the NSLog can be get. I changed a variety of methods to redirect logs, all of which are the same phenomenon. Anything wrong with my code?
