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

So 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 dont 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.

[ So 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…

Thank you for your help in advance

>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
