Designing a custom keyboard

I am trying to make a keyboard themed app. I created a custom keyboard file through the target, but the file I created does not have keyboard keys. How can I create a keyboardView and put the image I made into the keyboardView? There are too few related materials, so I need the help of experts.

Hard to say what is the problem without seeing any code…

Did you follow steps described here ?

https://developer.apple.com/documentation/uikit/keyboards_and_input/creating_a_custom_keyboard

This one goes through the full development of a custom keyboard:

Hope that helps.

After following the link, I came to know that the information was taught using a keyboard that was already made. But I want to make a keyboard like a keyboard already made.
