Themeable

Usage

Load your colors into Theme.shared using ThemeColors which conforms to Codeable, so you can load a JSON file from your Bundle (e.g. mytheme.json)

let myThemeColors = ThemeColors.load(bundle: "mytheme")

or any from any URL

let myThemeColors = ThemeColors.load(url: URL(string: "https://example.com/mytheme.json")!)

and apply the Theme using (if force is true it will also reload the current view=

Theme.shared.apply(force: true)

Example

Load your Theme mytheme.json at the start of the app.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    Theme.shared.colors = ThemeColors.from(bundle: "mytheme")
    Theme.shared.apply(force: true)
    return true
}

Advanced

If your app is using Eureka you can enable support for it with Theme.shared.eureka = true

If you want to customize the colors (for example a user customizable global tint color) before applying the theme you can do so in

Theme.shared.customColor {
	// Load custom Colors, e.g.
	Theme.shared.tint = ... // Load user tint 
}

You can also add your custom apperance setters here

Theme.shared.customAppearances {
	// Load custom appearances, e.g.
	UIButton.appearance(whenContainedInInstancesOf [MyViewController.self]).backgroundColor = .green
}
