Trying to get Data from the URL and get console warnings

I work in the Xcode 10 beta and iOS 12. Here is code snippet that appeared to be fine and do what it should do:

DispatchQueue.global().async {
    guard let imageUrl = URL(string: course.imageUrl!) else { return }
    guard let imageData = try? Data(contentsOf: imageUrl) else { return }
    DispatchQueue.main.async {
        cell.courseImage.image = UIImage(data: imageData)
    }
}

Next line:

guard let imageData = try? Data(contentsOf: imageUrl) else { return }

causes in simulator on iOS 12 next output in the console:

If I run iOS 11.4 simulator so message in the console will be other one and it appears after around 10-15 seconds:

[BoringSSL] Function boringssl_session_errorlog: line 2881 [boringssl_session_read] SSL_ERROR_ZERO_RETURN(6): operation failed because the connection was cleanly shut down with a close_notify alert

Why this messages are in the console if I'am just trying as usual to get Data from the URL?

Don’t worry, it’s not your fault. It’s OS logging and fortunately, you can turn it off.

Open Product ▶️ Scheme ▶️ Edit Scheme … Select Run On Environment Variables, add OS_ACTIVITY_MODE with value disable
