- **Flexible release history**: Unlike most What's New Screen libraries, Recap can display multiple releases, showcasing your app's entire feature history.
Release Title: [String]
Semantic Version Change Type: [Major | Minor | Patch]
- title: [String] (Feature Title)
- description: [String] (Feature Description)
- symbol: [String] (SF Symbol Identifier)
- color: [String] (Hex Color Code or System Color Name)
> [!NOTE]
> For a full list of supported System Color Names, see `Sources/Recap/Internal/Color+SystemNames.swift`.

With just a few lines of markdown we've built a Releases screen that has three pages, with a consistent look and feel.
### Customize Your Release Screen
Recap provides various modifiers to tailor the Releases screen to your app's visual identity:
```swift
// Available customization modifiers
func recapScreenStartIndex(_ startIndex: RecapScreenStartIndex) -> some View
func recapScreenTitleStyle(_ style: some ShapeStyle) -> some View
func recapScreenDismissButtonStyle(_ style: some ShapeStyle) -> some View
func recapScreenDismissButtonStyle(_ backgroundStyle: some ShapeStyle, _ foregroundStyle: some ShapeStyle) -> some View
func recapScreenDismissButtonTitle(_ title: LocalizedStringResource) -> some View
func recapScreenDismissButtonVisibility(_ visibility: RecapScreenDismissButtonVisibility) -> some View
func recapScreenIconFillMode(_ style: IconFillMode) -> some View
func recapScreenIconAlignment(_ alignment: VerticalAlignment) -> some View
func recapScreenPageIndicatorColors(selected: Color, deselected: Color) -> some View
func recapScreenPaginationStyle(_ style: RecapScreenPaginationStyle) -> some View
func recapScreenBackground(_ style: AnyShapeStyle?) -> some View
func recapScreenBackground(_ color: Color) -> some View
func recapScreenPadding(_ insets: EdgeInsets) -> some View
func recapScreenHeaderSpacing(_ spacing: CGFloat) -> some View
func recapScreenItemSpacing(_ spacing: CGFloat) -> some View
func recapScreenDismissAction(_ dismissAction: (() -> Void)?) -> some View
```
Example usage:
```swift
RecapScreen(releases: .appReleases)
.recapScreenTitleStyle(LinearGradient(colors: [.purple, .pink, .orange, .yellow], startPoint: .topLeading, endPoint: .bottomTrailing))
.recapScreenDismissButtonStyle(Color.pink, Color.white)
.recapScreenDismissButtonVisibility(.hidden)
.recapScreenIconFillMode(.gradient)
.recapScreenPaginationStyle(.automatic)
.recapScreenPageIndicatorColors(
selected: Color.pink,
deselected: Color.gray
)
```
Pagination styles:
- `.automatic`: uses the system page control on iPhone and iPad, and adaptive previous/next buttons on Mac Catalyst
- `.labeled`: always shows previous/next buttons with text labels
- `.compact`: always shows previous/next buttons as icon-only controls
RecapScreen also supports leading and trailing views:
```swift
RecapScreen(
releases: .plinkyReleases
leadingView: {
UpcomingRoadmapView()
}, trailingView: {
SupportView()
}
)
.recapScreenStartIndex(.release())
// Alternatively: .recapScreenStartIndex(.leadingView) or .recapScreenStartIndex(.trailingView)
```
In my app [Plinky](https://plinky.app), I use the leading view to display the app's upcoming roadmap ahead of the most recent features, and the trailing view displays a support screen for people to reach out to me after browsing the feature list.
### Display Policies
`RecapDisplayPolicy` and `RecapDisplayPolicy.Trigger` provide a handy way to define when your Recap screen should display. It encapsulates the most common strategies people choose for displaying a What's New screen, for example "when there's a new version that has release notes" or "if there are any release notes since the last version the user launched". It achieves this with a composable fluent syntax, and the rest is handled for you.
Below is a simplified example of how you can present a Recap screen. In this case we will display our screen when there are release notes for any version since the last launch, and the update is notable (major/minor).
```swift
func presentRecapScreen() {
let currentVersion = (Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as? String) ?? "0"
let previousVersion = UserDefaults.standard.string(forKey: "previouslyLaunchedVersion")
// Versions of your app that have release notes
let releaseVersions: [SemanticVersion] = [Release].appReleases.map(\.version.semanticVersion)
// Create a RecapDisplayPolicy based on the app's current version, the previously launched version, and your release notes.
let policy = RecapDisplayPolicy(
currentVersion: SemanticVersion(version: currentVersion),
previousVersion: previousVersion.map(SemanticVersion.init(version:)),
releases: releaseVersions
)
// A Trigger that shows the release notes for notable versions
// for a user who hasn't seen opened the app since the last version with release notes.
let trigger = RecapDisplayPolicy.Trigger
.updateWindow(.sincePrevious)
.notability(.notableOnly)
// An alternative example trigger that always shows release notes for any new version.
// let trigger = RecapDisplayPolicy.Trigger
// .updateWindow(.current)
// .notability(.any)
// .ignoringReleaseNotesRequirement()
if policy.shouldTrigger(using: trigger) {
// Present a RecapScreen in your app in a contextually relevant manner.
let recapScreen = RecapScreen(releases: .appReleases)
self.router.present(recapScreen)
}
// Persist version state for next launch
UserDefaults.standard.set(currentVersion, forKey: "previouslyLaunchedVersion")
}
```
### Semantic Versioning
Recap includes a `SemanticVersion` type to represent and compare versions using the standard `major.minor.patch` scheme. It powers the display policy described below and can be used directly anywhere version comparisons are needed.
Examples:
- `SemanticVersion(version: "1.2.3")`
- Compare with `==`, `<`, `>` to implement custom logic
### Demo
Try Recap with [the demo project](https://github.com/mergesort/Recap/tree/main/Demo) to see if it fits your app's needs. 📱
### Requirements
- iOS 17.0+
- Xcode 14+
### Installation
#### Swift Package Manager
The [Swift Package Manager](https://www.swift.org/package-manager) is a tool for automating the distribution of Swift code and is integrated into the Swift build system.
Once you have your Swift package set up, adding Recap as a dependency is as easy as adding it to the dependencies value of your `Package.swift`.
```swift
dependencies: [
.package(url: "https://github.com/mergesort/Recap/", from: Version(2, 0, 0))
]
```
#### Manually
If you prefer not to use SPM, you can integrate Recap into your project manually by copying the files in.
