Accessory View Not Displayed When Switching Input Methods via Bluetooth Keyboard
Hello everyone, When I press Control + Space on my Bluetooth keyboard to trigger input method switching, the accessory view fails to appear. This prevents me from quickly identifying the current input method type. Upon inspecting the View Hierarchy, I noticed that UICursorAccessoryView is not being created. For context, my input method responder inherits from UIResponder and conforms to the UITextInputTraits, UIKeyInput, and UITextInput protocols. The accessory view displays normally during accented input and Chinese input. Could you please guide me on how to troubleshoot this issue?

PrintCore API is lagging on the Sequoia
The performance of the PrintCore API on macOS Sequoia system has significantly deteriorated. When switching between page options in the print dialog, the application hangs. It can be observed through Instruments that the execution time of PrintCore() is higher on the Sequoia system than on the Sonoma system. 479.00 ms 17.0% 0 s PMBaseObject::PMBaseObject(char const*) 456.00 ms 16.2% 0 s PMBaseObject::~PMBaseObject()

The window resizing and placement feature is not working.
The new window resizing and placement feature of macOS Sequoia is not working in my application, and I don't know why. What's worse, I haven't consulted any relevant documents.
