// Formatting
    .foregroundColor(
        .black // System Color
        Color("AssetName") // Assets.xcassets
        UIColor(red:(16/255), green:(16/255), blue:(16/255), alpha: 1) // UI Color Value

    .kerning(1.0)
        // - Parameter kerning: How many points the following character should be
        //   shifted from its default offset as defined by the current character's
        //   font in points; a positive kerning indicates a shift farther along
        //   and a negative kern indicates a shift closer to the current character.
    .tracking(1.0)
        // - Parameter tracking: The tracking attribute indicates how much
        //   additional space, in points, should be added to each character cluster
        //   after layout. The effect of this attribute is similar to `kerning()`
        //   but differs in that the added tracking is treated as trailing
        //   whitespace and a non-zero amount disables non-essential ligatures.
        //   If both `kerning()` and `tracking()` are present, `kerning()` will be
        //   ignored; `tracking()` will still be honored.
    .baselineOffset(1.0)

// View Extensions
    .multilineTextAlignment(.leading) // leading, center, trailing
    .truncationMode(.tail) // head, middle, tail
    .lineSpacing(1.0)
        // - Parameter lineSpacing: The amount of space between the bottom of one
        //   line and the top of the next line.
    .allowsTightening(true)
        // - Parameter flag: A Boolean value that indicates whether the space
        //   between characters compresses when necessary.
    .lineLimit(3)
        // Sets the maximum number of lines that text can occupy in this view.
    .minimumScaleFactor(1.0)
        // - Parameter factor: A fraction between 0 and 1 (inclusive) you use to
        //   specify the minimum amount of text scaling that this view permits.
