Draw circles on points on UIImage in Swift

[albertski]

In my controller, I look at images in an album and select 3 random points on one image. I would like to have a way to circle these 3 points on the image so the user knows which points I am referring to.

I found this article that does something similar but it is old and not in Swift. Also, was hoping not to create a new image like he is in that article.

Does anyone have any recommendations on how to implement this?

Hi @albertski,
There are a couple of ways to do that.

One way could be to create a view that is centred at the points you have chosen. This could be a shape Layer of type circle. The other way is that you could draw the same on the view using CoreGraphics.

cheers,
