How can I set a color to .foregroundColor() by using a String? i.e. "green" --> Color.green

I have this String "green" inside a constant (lernset.color). I would like to set a .foregroundColor() to a symbol (systemName: "folder") inside of a list, so that it has the same color as written inside the constant (lernset.color). The problem I get: I don't know how to convert this constant (lernset.color) which has the datatype of a String into the datatype of Color.

I already tried:

  1. ... .foregroundColor(Color.lernset.color)
  2. ... .foregroundColor(Color.String(lernset.color))
  3. I also tried assigning the constant to a variable

but nothing worked.

Normally you would type: .foregroundColor(Color.green) But in this case I want the List to automatically adapt, so that the Color could change the way the constant (lernset.color) changes.

Solution

  • Use

    Color(lernset.color)

    It only works if the String value of lernset.color is defined as a Color Set in Assets

    This

    Color.lernset.color

    or

    Color.green

    References a static variable. You would need something like

    extension Color{
    static let yourColor: Color = Color("nameHere")
}

    Then you can call

    Color.yourColor

    With "nameHere" being the name of a Color Set
