Why can't I get a push message in Swift5? - ios

Question

I am currently trying to get a push message. However, you cannot receive a push message. What am I missing?

I don't get anything. My app doesn't receive push messages whether it's in the foreground or in the background.
Please help me a lot.
The token you added in the figure is the device token value. Token values are visible in the log.
EDIT
I saw the answer and followed it, but it doesn't work.

Can you Put GoogleService-Info.plist file in your project?
Try This In My Code 100% Working

I saw the answer and followed it, but it doesn't work. However, when you added a new project on the Fire Base, added the iOS app again, and tried, it was successful. I'm not sure what's wrong. Was that a problem with my code?I thought, but when I used the code in the question,also it worked. I simply created and added a new project for my solution.
