I'm currrently working through the book, Hacking with MacOS: SwiftUI Edition, and on project 3 there is: “For a bigger challenge, go back to project 2 and make the result text show in different colors depending on how close the user is: red for 0 cows 0 bulls, yellow for anything between 1 and 3 cows, and green for 4 cows"

You can look at the code for project 2 here:https://github.com/twostraws/macOS/tree/main/SwiftUI/project2/CowsAndBulls

I was wondering if anyone could help point me in the right direction with how to go about this challenge?

Hey there :) I hope it is not to late... I am completly new to Swift UI and Mac OS in generall, so it is, perhaps, not the best solution. Here is what i am done. I'm using a View for that:

struct ColoredText: View {
  let text: String
  let result: String
  private var color: Color {
    if result.contains("0🐄") {
      return .red
    } else if result.contains("4🐄") {
      return .green
    }
    return .yellow
  }

  var body: some View {
    Text(text)
      .foregroundStyle(color)
  }
}

placing it over the ContentView in the same file... (and i use emoji's insted of "c" for the cow)

and in "ContentView.swift" Line 35 (github example) replace

Text(guess)

with

ColoredText(text: guess, result: result(for: guess))
