SwiftUI: Markdown support for string variables

struct MarkdownTest: View {
  var text: String = "**Hello** *World*"
  var body: some View {
    VStack {
      Text("**Hello** *World*") // will be rendered with markdown formatting
      Text(text) // will NOT be rendered according to markdown
    }
  }
}

Here how to fix.


      Text(.init(text)) // this renders markdown properly

These icons are called SF Symbols. There are over 2,400 symbols you can use in iOS 13and later, macOS 11 and later, watchOS 6 and later, and tvOS 13 and later. You can use a symbol everywhere you can use an image.

To browse the full set of symbols, download the SF Symbols app. For more info about SF Symbols check here.

SF Symbols 2 introduces over 750 new symbols and includes:

  • Over 150 preconfigured, multicolor symbols that automatically adapt to vibrancy, accessibility settings, and appearance modes
  • Negative side margins in both standard and custom symbols, giving you greater control over horizontal alignment
  • Localized symbol variants for right-to-left writing systems, as well as script-specific symbols for Arabic, Devanagari, and Hebrew

Usage

UIKit:

let heartImage = UIImage(systemName: "heart.fill")

SwiftUI:

let heartImage = Image(systemName: "heart.fill")
