In my iOS app, there is a noticeable stutter the first time a text field is tapped. Additionally, I occasionally see the following debug message in the console:

Can't find or decode reasons

Failed to get or decode unavailable reasons

-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:]  perform input operation requires a valid sessionID. inputModality = Keyboard, inputOperation = <null selector>, customInfoType = UIEmojiSearchOperations

Question:

• Why does the app stutter on the first tap of the text field?

• Is the debug log related to the stutter? How can I further analyze and resolve this issue?
