ios - SwiftUI tappable subtext

Question

Is there any way in SwiftUI to open browser, when tapping on some part of the text.

I tried the above solution but it doesn't work because onTapGesture returns View which you cannot add to Text

Text("Some text ").foregroundColor(Color(UIColor.systemGray)) +
Text("clickable subtext")
   .foregroundColor(Color(UIColor.systemBlue))
   .onTapGesture {

   }

I want to have tappable subtext in the main text that's why using HStack will not work

Answer 1

Update for iOS 15 and higher: There is a new Markdown formatting support for Text, such as:

Text("Some text [clickable subtext](some url) *italic ending* ")

The old answer for iOS 13 and 14:

Unfortunately there is nothing that resembles NSAttributedString in SwiftUI. And you have only a few options. In this answer you can see how to use UIViewRepresentable for creating an old-school UILabel with click event, for example. But now the only SwiftUI way is to use HStack:

struct TappablePieceOfText: View {
    
    var body: some View {
        
        HStack(spacing: 0) {
            Text("Go to ")
                .foregroundColor(.gray)

            Text("stack overflow")
                .foregroundColor(.blue)
                .underline()
                .onTapGesture {
                    let url = URL.init(string: "https://stackoverflow.com/")
                    guard let stackOverflowURL = url, UIApplication.shared.canOpenURL(stackOverflowURL) else { return }
                    UIApplication.shared.open(stackOverflowURL)
                }
            
            Text(" and enjoy")
                .foregroundColor(.gray)
        }
        
        
    }
}

UPDATE Added solution with UITextView and UIViewRepresentable. I combined everything from added links and the result is quite good, I think:

import SwiftUI
import UIKit

struct TappablePieceOfText: View {
    
    var body: some View {
        TextLabelWithHyperlink()
            .frame(width: 300, height: 110)
    }
    
}

struct TextLabelWithHyperlink: UIViewRepresentable {
    
    func makeUIView(context: Context) -> UITextView {
        
        let standartTextAttributes: [NSAttributedString.Key : Any] = [
            NSAttributedString.Key.font: UIFont.systemFont(ofSize: 20),
            NSAttributedString.Key.foregroundColor: UIColor.gray
        ]
        
        let attributedText = NSMutableAttributedString(string: "You can go to ")
        attributedText.addAttributes(standartTextAttributes, range: attributedText.range) // check extention
        
        let hyperlinkTextAttributes: [NSAttributedString.Key : Any] = [
            NSAttributedString.Key.font: UIFont.systemFont(ofSize: 20),
            NSAttributedString.Key.foregroundColor: UIColor.blue,
            NSAttributedString.Key.underlineStyle: NSUnderlineStyle.single.rawValue,
            NSAttributedString.Key.link: "https://stackoverflow.com"
        ]
        
        let textWithHyperlink = NSMutableAttributedString(string: "stack overflow site")
        textWithHyperlink.addAttributes(hyperlinkTextAttributes, range: textWithHyperlink.range)
        attributedText.append(textWithHyperlink)
        
        let endOfAttrString = NSMutableAttributedString(string: " end enjoy it using old-school UITextView and UIViewRepresentable")
        endOfAttrString.addAttributes(standartTextAttributes, range: endOfAttrString.range)
        attributedText.append(endOfAttrString)
        
        let textView = UITextView()
        textView.attributedText = attributedText
        
        textView.isEditable = false
        textView.textAlignment = .center
        textView.isSelectable = true
        
        return textView
    }

    func updateUIView(_ uiView: UITextView, context: Context) {}
    
}

result of HStack and Text:

result of UIViewRepresentable and UITextView:

UPDATE 2: here is a NSMutableAttributedString little extension:

extension NSMutableAttributedString {
    
    var range: NSRange {
        NSRange(location: 0, length: self.length)
    }
    
}
