Colors

Part of the Introduction to SwiftUI section of Coddy's Swift journey. Lesson 6 of 50.

.foregroundStyle colors a view's content, such as the letters of a Text:

Text("Warning")
    .foregroundStyle(.red)

SwiftUI has named colors: .red, .orange, .yellow, .green, .blue, .purple, .gray and more. .secondary is the softer gray used for less important text.

Older code uses .foregroundColor(.red), which does the same for a single color. You can also mix a color from red, green and blue parts between 0 and 1:

Text("Custom")
    .foregroundStyle(Color(red: 0.2, green: 0.6, blue: 0.9))

Challenge

Beginner

Show that the cafe is open: make the text green and give it the .headline font.
