Is there any up to date way to convert links inside the text? I'm getting this kind of text from an API:
var someText: String = "with banks (for example to the sometimes controversial but leading exchange <a href="https://www.coingecko.com/en/exchanges/bitfinex">Bitfinex</a>)."
How can I convert that link inside to a clickable link with the proper name, in the example above: Bitfinex ?
The text could contain multiple links. SwiftUI now supports markdown, manually I could do it like:
Text("[Privacy Policy](https://example.com)")
but how do I do it for a received text from api with multiple links?
Looking for a Swift 5 & SwiftUI 3 solution.
What you have is an html string. You can interpret your html string using NSAttributedString initializer options NSAttributedString.DocumentType.html and initialize a new AttributedString with it. No need to manipulate and/or manually parse your string:
First add this extension to your project:
extension StringProtocol {
func htmlToAttributedString() throws -> AttributedString {
try .init(
.init(
data: .init(utf8),
options: [
.documentType: NSAttributedString.DocumentType.html,
.characterEncoding: String.Encoding.utf8.rawValue
],
documentAttributes: nil
)
)
}
}
Then extend Text to add a custom initializer:
extension Text {
init(html: String, alert: String? = nil) {
do {
try self.init(html.htmlToAttributedString())
} catch {
self.init(alert ?? error.localizedDescription)
}
}
}
import SwiftUI
struct ContentView: View {
var html = #"with banks (for example to the sometimes controversial but leading exchange <a href="https://www.coingecko.com/en/exchanges/bitfinex">Bitfinex</a>. For more info <a href="https://www.google.com/">Google</a>).""#
var body: some View {
Text(html: html)
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
