Build Status

Easy, type-safe UI theming in Swift.

This project is still in it’s early stages, so any and all feedback is welcome. Have any suggestions for how to make this library better? Please leave an issue :)

Pull requests are always very welcome.


  • Type-safe API
  • Transparent memory management
  • Automatically reuse last used theme
  • Thread safe UI updates
  • Theme Views and Controls without subclassing
  • Extremely flexible (build and load your theme the way that works for you)


Installing with CocoaPods:

# In your Podfile add the following, then
# save and run `pod install`:
pod 'Themeable'

Example Usage

import UIKit
import Themeable

// Define the theme and its properties to be used throughout your app
struct MyAppTheme: Theme {

    let identifier: String
    let seperatorColor: UIColor
    let lightBackgroundColor: UIColor
    let statusBarStyle: UIStatusBarStyle

    static let light = MyAppTheme(
        identifier: "co.brushedtype.Themeable.light-theme",
        seperatorColor: .lightGray,
        lightBackgroundColor: .white,
        statusBarStyle: .default

    static let dark = MyAppTheme(
        identifier: "co.brushedtype.Themeable.dark-theme",
        seperatorColor: .black,
        lightBackgroundColor: .gray,
        statusBarStyle: .lightContent

    // Expose the available theme variants
    static let variants: [MyAppTheme] = [ .light, .dark ]

    // Expose the shared theme manager
    static let manager = ThemeManager<MyAppTheme>(default: .light)


// Conform to the `Themeable` protocol and register for updates
class TableViewController: UITableViewController, Themeable {

    override func viewDidLoad() {

        // register the themeable items once all the view and subviews
        // have been loaded
        MyAppTheme.manager.register(themeable: self)

    // function will be called whenever the theme changes
    func apply(theme: MyAppTheme) {
        self.tableView.separatorColor = theme.seperatorColor
        self.tableView.backgroundColor = theme.lightBackgroundColor
