Can I get theme color

[brian8219]

For example I have assets like this
|-StyleA
| |-PrimaryColor
|-StyleB
|-PrimaryColor

Is it possible to get color like Asset.PrimaryColor.color?
And the color is depend on a property that store the current style.

SwiftGen won't do this for you (won't generate the code that does it).

What you can do is, assuming both "styles" have the same set of colors, create a protocol such as:

protocol Style {
  static var primaryColor: ColorAsset { get }
  …
}

And conform both StyleA and StyleB to your protocol like this:

extension Asset.StyleA: Style {}
extension Asset.StyleB: Style {}

Once all of that is set up, you'll probably have some style management service that will check some UserDefaults and decide which style to return:

extension StyleService {
  var activeStyle: Style {
    if someCondition {
      return Asset.StyleA
    } else {
      return Asset.StyleB
    }
  }

Something like that? Note that this isn't actually tested code, just something to push you into the right direction. All of the above should be possible without a custom template, but if you really want you could create your own template that does this 🤷
