Hello all. I have a need to replace the font for a specific character in a longer text string. I've been able to successfully acomplish this with Attibutedstrings. I have also been able to adjust the background color of this character to make it stand out. Now what i need to accomplish is turn that rectangular background color into a circle. I have not been able to find a way to do this with the attributed string. Is there a way to add rounded corners and/or a colored circle behind character using AttributedStrings?

Here is a sample of the code i am currently using. Again, this does work, but i would like to round the corners of the background into a circle.

let str = NSMutableAttributedString(string: strIn)
if strIn.contains("") {
        let substringRangeG = strIn.range(of: "")!
        let nsRangeG = NSRange(substringRangeG, in: strIn)
        str.addAttributes([.font: UIFont(name: "customFont", size: 16.0)!,.backgroundColor: UIColor(.green)], range: nsRangeG)
    }

Thanks in advance!

just giving this a bump. does anyone have any suggestions?

No way to do this with just NSAttributedString, I'm afraid. About the closest you could come would be to use a font that has circled characters and replace the uncircled character with its circled counterpart. But I don't think that would work with your background.

You could delve into using NSLayoutManager and try the approach used here: Adding custom attribute to NSAttributedString on iOS

Thanks @roosterboy. If i was to use NSTextAttachment and insert images of my custom font symbols with the circled background instead of swapping font types, is there a way to use ranges to add the NSTextAttachement, or would i just need to parse through my string picking appart the start and end portions and using append to put it back together with the image inserted in the middle?

I am trying to acheive something like this, inserted into a text string replacing that specific character with the colored background version.

Text("C")
    .foregroundColor(.white)
    .padding(10)
    .background(Color(.gray))
    .clipShape(Circle())
