How to add Activity Indivator ImageView.image?

Question

Images

Friends, I need help
1. The application implements an activityIndicator, and it is displayed while json loads an array of media.
2. But from the moment it is loaded until the photo appears, for example, on imageView, 1-1.6 seconds pass, when it is not there and the photo is not displayed.
3. I tried using dispatch to delay the display of the indicator for a given time difference, but I would not like a "crutch-style" solution
4. Does anyone have any ideas?
PS
Display via switch with check for nil imageView.image didn't work either

Answer 1

in the next line, how do you set the imageView.image value to hide the indicator
activityIndicator.stopAnimating()
activityIndicator.isHidden = true

Answer 2

I faced the same situation. I turned on the indicator at the beginning of the session and turned it off when it downloaded all the photos. I do not understand the complexity of the task.
