推荐答案

这是一个已知的问题，应用程序启动后首次打开时，键盘(无论是否自定义)可能加载缓慢.
仅在调试模式下发生，由于高度的优化，在发行版本中不应发生.

It's a known issue that the keyboard (custom or not) may load slowly the first time it's opened after the app launch.
It happens only in debug mode and should not happen on a release build thanks to the high optimization level.
