If you take a look at the documentation for that symbol, it says it is from iOS 14.0+.

Why you give same question dude ?i have answer your question

I asked if you have any warnings, and you replied that you didn’t have any errors. Errors and warnings are different. Based on AndyJJ’s note that that symbol is iOS 14 only, and as you’re compiling for iOS 12, you should get a warning from the compiler about that. So there are a couple of possibilities; one is that you are ignoring the warnings, in which case “naughty, don’t ignore the warnings!”, or for some reason the warning is not being generated, in which case that needs to be investigated, e.g. in your build settings.

P.S. Don’t post comments in this forum, always post replies; comments don’t generate email notifications, which is why I’ve not replied for a week.
