WhatsNewKit enables you to easily showcase your awesome new app features.
It’s designed from the ground up to be fully customized to your needs.

Example

Features

  • [x] Customization and Configuration to your needs 💪
  • [x] Predefined Themes and Animations 🎬
  • [x] Easily check if your Features have already been presented 🎁
  • [x] Awesome UI 😍

Example

The example Application is an excellent way to see WhatsNewKit in action. You get a brief look of the available configuration options and how they affect the look and feel of the WhatsNewViewController. Simply open the WhatsNewKit.xcodeproj and run the WhatsNewKit-Example scheme.

Installation

CocoaPods

WhatsNewKit is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'WhatsNewKit', '~> 1.0.0'

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

To integrate WhatsNewKit into your Xcode project using Carthage, specify it in your Cartfile:

github "SvenTiigi/WhatsNewKit" ~> 1.0.0

Run carthage update --platform iOS to build the framework and drag the built WhatsNewKit.framework into your Xcode project.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase” and add the Framework path as mentioned in Carthage Getting started Step 4, 5 and 6

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate WhatsNewKit into your project manually. Simply drag the Sources Folder into your Xcode project.

Usage

The following first usage description shows the easiest way of presenting your new app features with WhatsNewKit.

👨‍💻 Please see the Advanced section for further configuration options and features.

// Initialize WhatsNew
let whatsNew = WhatsNew(
    // The Title
    title: "WhatsNewKit",
    // The features you want to showcase
    items: [
        WhatsNew.Item(
            title: "Installation",
            subtitle: "You can install WhatsNewKit via CocoaPods or Carthage",
            image: .init(named: "installation")
        ),
        WhatsNew.Item(
            title: "Open Source",
            subtitle: "Contributions are very welcome 👨‍💻",
            image: .init(named: "openSource")
        )
    ]
)

// Initialize WhatsNewViewController with WhatsNew
let whatsNewViewController = WhatsNewViewController(
    whatsNew: whatsNew
)

// Present it 🤩
self.present(whatsNewViewController, animated: true)

Advanced

As mentioned before WhatsNewKit can be fully customized to your needs. The Advanced section will explain all configuration possibilities and features of WhatsNewKit in detail. First off it’s important to understand the components of the WhatsNewViewController in order to customize the behaviour and UI-Design.

WhatsNewKit

WhatsNewViewController.Configuration

The WhatsNewViewController.Configuration struct enables you to customize the WhatsNewViewController components to your needs. The configuration itself can be passed to the initializer of the WhatsNewViewController.

// Initialize default Configuration
var configuration = WhatsNewViewController.Configuration()

// Customize Configuration to your needs
configuration.backgroundColor = .white
configuration.titleView.titleColor = .orange
configuration.itemsView.titleFont = .systemFont(ofSize: 17)
configuration.detailButton.titleColor = .orange
configuration.completionButton.backgroundColor = .orange
// And many more configuration properties...

// Initialize WhatsNewViewController with custom configuration
let whatsNewViewController = WhatsNewViewController(
    whatsNew: whatsNew, 
    configuration: configuration
)

Theme

A Theme allows you to group the customization of a WhatsNewViewController.Configuration. WhatsNewKit implemented predefined Themes which are available as static properties both in white and dark mode. Or you create your very own Theme to configure it to your needs.

WhatsNewKit

// Configuration with predefined Dark Red Theme
let darkRed = WhatsNewViewController.Configuration(
    theme: .darkRed
)

// Apply predefined White Red Theme to Configuration
var configuration = WhatsNewViewController.Configuration()
configuration.apply(theme: .whiteRed)

// Or create your own Theme and initialize a Configuration with your Theme
let myTheme = WhatsNewViewController.Theme { configuration in
    // Apply customizations ...
}
let configuration = WhatsNewViewController.Configuration(
    theme: myTheme
)

For a full overview of the available predefined Themes check out the Example-Application.

Animation

Animations

You can apply a Animation to all components of the WhatsNewViewController via predefined animation types. In default all Animation properties are nil indicating no animation should be perfomed.

// Set SlideUp Animation to TitleView
configuration.titleView.animation = .slideUp

// Set SlideRight Animation to ItemsView
configuration.itemsView.animation = .slideRight

// Set SlideLeft Animation to DetailButton
configuration.detailButton.animation = .slideLeft

// Set SlideDown Animation to CompletionButton
configuration.completionButton.animation = .slideDown

If you wish to animate all views with the same type you can do so by simply applying it to the configuration.

// Global Animation-Type for all WhatsNewViewController components
configuration.apply(animation: .fade)

If you wish to define your custom animation, simply set the custom enum and pass an animator closure.

// Custom Animation for DetailButton
configuration.detailButton.animation = .custom(animator: { [weak self] (view: UIView, settings: AnimatorSettings) in
    // view: The View to perform animation on
    // settings: Preferred duration and delay
})

DetailButton

DetailButton

By setting an DetailButton struct on the WhatsNewViewController.Configuration struct you can customize the title and the corresponding action of the displayed detail button on the WhatsNewViewController. As the DetailButton struct is declared as optional the WhatsNewViewController will only display the button if a DetailButton configuration is available

Action Description
website When the user pressed the detail button a SFSafariViewController with the given URL will be presented
custom After the detail button has been pressed by the user, your custom action will be invoked
// Initialize DetailButton with title and open website at url
let detailButton = WhatsNewViewController.DetailButton(
    title: "Read more", 
    action: .website(url: "https://github.com/SvenTiigi/WhatsNewKit")
)

// Initialize DetailButton with title and custom action
let detailButton = WhatsNewViewController.DetailButton(
    title: "Read more", 
    action: .custom(action: { [weak self] whatsNewViewController in
        // Perform custom action on detail button pressed
    })
)

CompletionButton

CompletionButton

The CompletionButton struct configures the displayed title and the action when the user pressed the completion button on the WhatsNewViewController.

Action Description
dismiss When the user pressed the completion button, the WhatsNewViewController will be dismissed. This is the default value
custom After the completion button has been pressed by the user, your custom action will be invoked
// Initialize CompletionButton with title and dismiss action
let completionButton = WhatsNewViewController.CompletionButton(
    title: "Continue", 
    action: .dismiss
)

// Initialize CompletionButton with title and custom action
let completionButton = WhatsNewViewController.CompletionButton(
    title: "Continue", 
    action: .custom(action: { [weak self] whatsNewViewController in
        // Perform custom action on completion button pressed
    })
)

HapticFeedback

You can enable on both DetailButton and CompletionButton haptic feedback when the user pressed one of these buttons. Either by setting the property or passing it to the initializer.

// Impact Feedback
button.hapticFeedback = .impact(.medium)

// Selection Feedback
button.hapticFeedback = .selection

// Notification Feedback with type
let completionButton = WhatsNewViewController.CompletionButton(
    title: "Continue", 
    action: .dismiss,
    hapticFeedback: .notification(.success)
)

☝️ In default the HapticFeedback is nil indicating no haptic feedback should be executed.

WhatsNewVersionStore

WhatsNewVersionStore

If we speak about presenting awesome new app features we have to take care that this kind of UI action only happens once if the user installed the app or opened it after an update. The WhatsNewKit offers a protocol oriented solution for this kind of problem via the WhatsNewVersionStore protocol.

/// WhatsNewVersionStore typealias protocol composition
public typealias WhatsNewVersionStore = WriteableWhatsNewVersionStore & ReadableWhatsNewVersionStore

public protocol WriteableWhatsNewVersionStore {
    func set(version: WhatsNew.Version)
}

public protocol ReadableWhatsNewVersionStore {
    func has(version: WhatsNew.Version) -> Bool
}

The WhatsNewViewController will use the APIs of the WhatsNewVersionStore in the following way.

API Description
has(version:) Checks if the Whatsnew.Version is available and will return nil during initialization.
set(version:) The WhatsNew.Version will be set after the CompletionButton has been pressed.

The WhatsNewVersionStore can be passed as an parameter to the initializer. If you do so the initializer will become optional.

// Initialize WhatsNewViewController with WhatsNewVersionStore
let whatsNewViewController: WhatsNewViewController? = WhatsNewViewController(
    whatsNew: whatsNew, 
    versionStore: myVersionStore
)

// Check if WhatsNewViewController is available to present it.
if let controller = whatsNewViewController {
    // Present it as WhatsNewViewController is available 
    // after init with WhatsNewVersionStore
    self.present(controller, animated: true)
} else {
    // WhatsNewViewController is `nil` this Version has already been presented
}

// Or invoke present on the WhatsNewViewController
// to avoid the need of unwrapping the optional
whatsNewViewController?.present(on: self)

☝️ Please keep in mind the WhatsNewViewController initializer will only become optional and checks if the Version has been already presented if you pass a WhatsNewVersionStore object.

Implementation

If you already handled saving user settings in your app to something like Realm, CoreData or UserDefaults you can conform that to the WhatsNewVersionStore.

// Extend your existing App-Logic
extension MyUserSettingsDatabase: WhatsNewVersionStore {
    // Implement me 👨‍💻
}

Predefined Implementations

WhatsNewKit brings along two predefined Implementations of the WhatsNewVersionStore.

KeyValueWhatsNewVersionStore

The KeyValueWhatsNewVersionStore saves and retrieves the WhatsNew.Version via a KeyValueable protocol conform object. UserDefaults and NSUbiquitousKeyValueStore are already conform to that protocol 🙌

// Local KeyValueStore
let keyValueVersionStore = KeyValueWhatsNewVersionStore(
    keyValueable: UserDefaults.standard
)

// iCloud KeyValueStore
let keyValueVersionStore = KeyValueWhatsNewVersionStore(
    keyValueable: NSUbiquitousKeyValueStore.default
)

// Initialize WhatsNewViewController with KeyValueWhatsNewVersionStore
let whatsNewViewController: WhatsNewViewController? = WhatsNewViewController(
    whatsNew: whatsNew, 
    versionStore: keyValueVersionStore
)
InMemoryWhatsNewVersionStore

The InMemoryWhatsNewVersionStore saves and retrieves the WhatsNew.Version in memory. Perfect for development or testing phase 👨‍💻

// Initialize WhatsNewViewController with InMemoryWhatsNewVersionStore
let whatsNewViewController: WhatsNewViewController? = WhatsNewViewController(
    whatsNew: whatsNew, 
    versionStore: InMemoryWhatsNewVersionStore()
)

WhatsNew.Version

During the initialization of the WhatsNew struct the WhatsNewKit will automatically retrieve the current App-Version via the CFBundleShortVersionString and construct a WhatsNew.Version for you which is used by the WhatsNewVersionStore protocol in order to persist the presented app versions. If you want to manually set the version you can do it like the following example.

// Initialize Version 1.0.0
let version = WhatsNew.Version(
    major: 1,
    minor: 0,
    patch: 0
)

// Use a String literal
let version = WhatsNew.Version(stringLiteral: "1.0.0")

// Current Version in Bundle (Default)
let version = WhatsNew.Version.current()

After you initialize a WhatsNew.Version you can pass it to the initializer of a WhatsNew struct.

// Initialize WhatsNew with Title and Items
let whatsNew = WhatsNew(
    version: version,
    title: "WhatsNewKit",
    items: []
)

If you holding multiple WhatsNew structs in an array you can make use of the following two functions to retrieve a WhatsNew struct based on the WhatsNewVersion.

let whatsNews: [WhatsNew] = [...]

// Retrieve WhatsNew from array based on Version 1.0.0
let whatsNewVersion1 = whatsNews.get(byVersion:
    .init(major: 1, minor: 0, patch: 0)
)

// Or retrieve it via String as WhatsNew.Version is
// conform to the ExpressibleByStringLiteral protocol
let whatsNewVersion2 = whatsNews.get(byVersion: "2.0.0")

// If you want the WhatsNew for your current App-Version
// based on the CFBundleShortVersionString from Bundle.main
let currentWhatsNew = whatsNews.get()

Codable WhatsNew

The WhatsNew struct is conform the Codable protocol which allows you to initialize a WhatsNew struct via JSON.

{
    "version": {
        "major": 1,
        "minor": 0,
        "patch": 0
    },
    "title": "WhatsNewKit",
    "items": [
        {
            "title": "Open Source",
            "subtitle": "Contributions are very welcome 👨‍💻",
            "image": "data:image/png;base64,R0lG42......."
        }
    ]
}

The optional image property of the WhatsNew.Item will be decoded and encoded in Base64.

// Encode to JSON
let encoded = try? JSONEncoder().encode(whatsNew)

// Decode from JSON data
let decoded = try? JSONDecoder().decode(WhatsNew.self, from: data)
