Manual Presentation

If you wish to manually present a WhatsNewView you can make use of the sheet(whatsNew:) modifier.

struct ContentView: View {

    @State
    var whatsNew: WhatsNew? = WhatsNew(
        title: "WhatsNewKit",
        features: [
            .init(
                image: .init(
                    systemName: "star.fill",
                    foregroundColor: .orange
                ),
                title: "Showcase your new App Features",
                subtitle: "Present your new app features..."
            ),
            // ...
        ]
    )
    
    var body: some View {
        NavigationView {
            // ...
        }
        .sheet(
            whatsNew: self.$whatsNew
        )
    }
    
}

Automatic Presentation

The automatic presentation mode allows you to simply declare your new features via the SwiftUI Environment and WhatsNewKit will take care to present the corresponding WhatsNewView.

First add a .whatsNewSheet() modifier to the view where the WhatsNewView should be presented on.

struct ContentView: View {

    var body: some View {
        NavigationView {
            // ...
        }
        // Automatically present a WhatsNewView, if needed.
        // The WhatsNew that should be presented to the user
        // is automatically retrieved from the `WhatsNewEnvironment`
        .whatsNewSheet()
    }

}

The .whatsNewSheet() modifier is making use of the WhatsNewEnvironment to retrieve an optional WhatsNew object that should be presented to the user for the current version. Therefore you can easily configure the WhatsNewEnvironment via the environment modifier.

extension App: SwiftUI.App {
    
    var body: some Scene {
        WindowGroup {
            ContentView()
                .environment(
                    \.whatsNew, 
                    WhatsNewEnvironment(
                        // Specify in which way the presented WhatsNew Versions are stored.
                        // In default the `UserDefaultsWhatsNewVersionStore` is used.
                        versionStore: UserDefaultsWhatsNewVersionStore(),
                        // Pass a `WhatsNewCollectionProvider` or an array of WhatsNew instances
                        whatsNewCollection: self
                    )
                )
        }
    }

}

// MARK: - App+WhatsNewCollectionProvider

extension App: WhatsNewCollectionProvider {

    /// Declare your WhatsNew instances per version
    var whatsNewCollection: WhatsNewCollection {
        WhatsNew(
            version: "1.0.0",
            // ...
        )
        WhatsNew(
            version: "1.1.0",
            // ...
        )
        WhatsNew(
            version: "1.2.0",
            // ...
        )
    }

}

WhatsNewEnvironment

The WhatsNewEnvironment will take care to determine the matching WhatsNew object that should be presented to the user for the current version.

As seen in the previous example you can initialize a WhatsNewEnvironment by specifying the WhatsNewVersionStore and providing a WhatsNewCollection.

// Initialize WhatsNewEnvironment by passing an array of WhatsNew Instances.
// UserDefaultsWhatsNewVersionStore is used as default WhatsNewVersionStore
let whatsNewEnvironment = WhatsNewEnvironment(
    whatsNewCollection: [
        WhatsNew(
            version: "1.0.0",
            // ...
        )
    ]
)

// Initialize WhatsNewEnvironment with NSUbiquitousKeyValueWhatsNewVersionStore
// which stores the presented versions in iCloud.
// WhatsNewCollection is provided by a `WhatsNewBuilder` closure
let whatsNewEnvironment = WhatsNewEnvironment(
    versionStore: NSUbiquitousKeyValueWhatsNewVersionStore(),
    whatsNewCollection: {
        WhatsNew(
            version: "1.0.0",
            // ...
        )
    }
)

Additionally, the WhatsNewEnvironment includes a fallback for patch versions. For example when a user installs version 1.0.1 and you only have declared a WhatsNew for version 1.0.0 the environment will automatically fallback to version 1.0.0 and present the WhatsNewView to the user if needed.

If you wish to further customize the behaviour of the WhatsNewEnvironment you can easily subclass it and override the whatsNew() function.

class MyCustomWhatsNewEnvironment: WhatsNewEnvironment {
    
    /// Retrieve a WhatsNew that should be presented to the user, if available.
    override func whatsNew() -> WhatsNew? {
        // The current version
        let currentVersion = self.currentVersion
        // Your declared WhatsNew objects
        let whatsNewCollection = self.whatsNewCollection
        // The WhatsNewVersionStore used to determine the already presented versions
        let versionStore = self.whatsNewVersionStore
        // TODO: Determine WhatsNew that should be presented to the user...
    }
    
}

WhatsNewVersionStore

A WhatsNewVersionStore is a protocol type which is responsible for saving and retrieving versions that have been presented to the user.

let whatsNewVersionStore: WhatsNewVersionStore

// Save presented versions
whatsNewVersionStore.save(presentedVersion: "1.0.0")

// Retrieve presented versions
let presentedVersions = whatsNewVersionStore.presentedVersions

// Retrieve bool value if a given version has already been presented
let hasPresented = whatsNewVersionStore.hasPresented("1.0.0")

WhatsNewKit comes along with three predefined implementations:

// Persists presented versions in the UserDefaults
let userDefaultsWhatsNewVersionStore = UserDefaultsWhatsNewVersionStore()

// Persists presented versions in iCloud using the NSUbiquitousKeyValueStore
let ubiquitousKeyValueWhatsNewVersionStore = NSUbiquitousKeyValueWhatsNewVersionStore()

// Stores presented versions in memory. Perfect for testing purposes
let inMemoryWhatsNewVersionStore = InMemoryWhatsNewVersionStore()

If you already have a specific implementation to store user related settings like Realm or Core Data you can easily adopt your existing implementation to the WhatsNewVersionStore protocol.

NSUbiquitousKeyValueWhatsNewVersionStore

If you are making use of the NSUbiquitousKeyValueWhatsNewVersionStore please ensure to enable the iCloud Key-value storage capability in the "Signing & Capabilities" section of your Xcode project.

iCloud Key-value storage

WhatsNew

The following sections explains how a WhatsNew struct can be initialized in order to describe the new features for a given version of your app.

let whatsnew = WhatsNew(
    // The Version that relates to the features you want to showcase
    version: "1.0.0",
    // The title that is shown at the top
    title: "What's New",
    // The features you want to showcase
    features: [
        WhatsNew.Feature(
            image: .init(systemName: "star.fill"),
            title: "Title",
            subtitle: "Subtitle"
        )
    ],
    // The primary action that is used to dismiss the WhatsNewView
    primaryAction: WhatsNew.PrimaryAction(
        title: "Continue",
        backgroundColor: .accentColor,
        foregroundColor: .white,
        hapticFeedback: .notification(.success),
        onDismiss: {
            print("WhatsNewView has been dismissed")
        }
    ),
    // The optional secondary action that is displayed above the primary action
    secondaryAction: WhatsNew.SecondaryAction(
        title: "Learn more",
        foregroundColor: .accentColor,
        hapticFeedback: .selection,
        action: .openURL(
            .init(string: "https://github.com/SvenTiigi/WhatsNewKit")
        )
    )
)

WhatsNew.Version

The WhatsNew.Version specifies the version that has introduced certain features to your app.

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

// Initialize by string literal
let version: WhatsNew.Version = "1.0.0"

// Initialize WhatsNew Version by using the current version of your bundle
let version: WhatsNew.Version = .current()

WhatsNew.Title

A WhatsNew.Title represents the title text that is rendered above the features.

// Initialize by string literal
let title: WhatsNew.Title = "Continue"

// Initialize with text and foreground color
let title = WhatsNew.Title(
    text: "Continue",
    foregroundColor: .primary
)

// On >= iOS 15 initialize with AttributedString using Markdown
let title = WhatsNew.Title(
    text: try AttributedString(
        markdown: "What's **New**"
    )
)

WhatsNew.Feature

A WhatsNew.Feature describe a specific feature of your app and generally consist of an image, title, and subtitle.

let feature = WhatsNew.Feature(
    image: .init(
        systemName: "wand.and.stars"
    ),
    title: "New Design",
    subtitle: .init(
        try AttributedString(
            markdown: "An awesome new _Design_"
        )
    )
)

WhatsNew.PrimaryAction

The WhatsNew.PrimaryAction allows you to configure the behaviour of the primary button which is used to dismiss the presented WhatsNewView

let primaryAction = WhatsNew.PrimaryAction(
    title: "Continue",
    backgroundColor: .blue,
    foregroundColor: .white,
    hapticFeedback: .notification(.success),
    onDismiss: {
        print("WhatsNewView has been dismissed")
    }   
)

Note: HapticFeedback will only be executed on iOS

WhatsNew.SecondaryAction

A WhatsNew.SecondaryAction which is displayed above the WhatsNew.PrimaryAction can be optionally supplied when initializing a WhatsNew instance and allows you to present an additional View, perform a custom action or open an URL.

// SecondaryAction that presents a View
let secondaryActionPresentAboutView = WhatsNew.SecondaryAction(
    title: "Learn more",
    foregroundColor: .blue,
    hapticFeedback: .selection,
    action: .present {
        AboutView()
    }  
)

// SecondaryAction that opens a URL
let secondaryActionOpenURL = WhatsNew.SecondaryAction(
    title: "Read more",
    foregroundColor: .blue,
    hapticFeedback: .selection,
    action: .open(
        url: .init(string: "https://github.com/SvenTiigi/WhatsNewKit")
    )  
)

// SecondaryAction with custom execution
let secondaryActionCustom = WhatsNew.SecondaryAction(
    title: "Custom",
    action: .custom { presentationMode in
        // ...
    }
)

Note: HapticFeedback will only be executed on iOS

Layout

WhatsNewKit allows you to adjust the layout of a presented WhatsNewView in various ways.

The most simple way is by mutating the WhatsNew.Layout.default instance.

WhatsNew.Layout.default.featureListSpacing = 35

When using the automatic presentation style you can supply a default layout when initializing the WhatsNewEnvironment.

.environment(
    \.whatsNew,
    .init(
        defaultLayout: WhatsNew.Layout(
            showsScrollViewIndicators: true,
            featureListSpacing: 35
        ),
        whatsNew: self
    )
)

Alternatively you can pass a WhatsNew.Layout when automatically or manually presenting the WhatsNewView

.whatsNewSheet(
    layout: WhatsNew.Layout(
        contentPadding: .init(
            top: 80, 
            leading: 0,
            bottom: 0,
            trailing: 0
        )
    )
)
.sheet(
    whatsNew: self.$whatsNew,
    layout: WhatsNew.Layout(
        footerActionSpacing: 20
    )
)

WhatsNewViewController

When using UIKit or AppKit you can make use of the WhatsNewViewController.

let whatsNewViewController = WhatsNewViewController(
    whatsNew: WhatsNew(
        version: "1.0.0",
        // ...
    ),
    layout: WhatsNew.Layout(
        contentSpacing: 80
    )
)

If you wish to present a WhatsNewViewController only if the version of the WhatsNew instance has not been presented you can make use of the convenience failable initializer.

// Verify WhatsNewViewController is available for presentation
guard let whatsNewViewController = WhatsNewViewController(
    whatsNew: WhatsNew(
        version: "1.0.0",
        // ...
    ),
    versionStore: UserDefaultsWhatsNewVersionStore()
) else {
    // Version of WhatsNew has already been presented
    return
}

// Present WhatsNewViewController
// Version will be automatically saved in the provided
// WhatsNewVersionStore when the WhatsNewViewController gets dismissed
self.present(whatsNewViewController, animated: true)
