Thank you for answering my question. I tried it and I got the result I wanted. I really thank you.

Thank you for your advice. I tried it and I got the button I wanted. The code is a little bit difficult for me but it is so helpful. I am learning Swift(UI) everyday.

Thank you for your advice. I tried it and I almost got what I wanted. Unfortunately, there is a subtlety: there are two tap actions, on the button part and the other part. I need some control but I am so glad that I could almost get the button I wanted.
