How to make a cocoapods sample with a common touch

Hello
I am a beginner at xcode.
Does it appear when I touch the screen?Things. If you let them go, they will disappear, and if you keep touching them, they will show a circle all the whole time.I would like to make something like that.
I often see samples of Cocoapods, but how should I make them?
Also, I would like to display circles and animations where one finger and three fingers are placed.
For now, if you touch it with UIGestureRecognizerDelegate, it will count on the label.I tried to press it after touching it for a long time, and when I finished, I put it on the label end.
I'm sorry to bother you.Please give me some advice.
Thank you for your cooperation.
