Implement and review Apple TipKit feature-discovery UI for iOS 17+ apps. Use when adding or auditing in-app tips, contextual help, coach marks, Tip, TipView, popoverTip, rules, events, actions, display frequency, testing overrides, reusable tip identifiers, or iOS 18+ TipGroup and CloudKit tip sync; avoid for generic SwiftUI navigation or layout outside tip presentation.

TipKit

Use TipKit for small, contextual feature-discovery moments: inline tips, popover tips, rule-gated education, and lightweight coach marks. Keep generic SwiftUI architecture, navigation, layout, and long first-run onboarding flows in their sibling skills unless TipKit presentation is the core issue.

Availability

TipKit's core Tip, TipView, popoverTip, rules, events, options, and testing overrides are available on iOS 17+, iPadOS 17+, macOS 14+, tvOS 17+, watchOS 10+, and visionOS 1+.

Gate newer APIs explicitly:

APIAvailabilityUse
TipGroupiOS 18+Defaults to .firstAvailable; use .ordered only for sequences where later tips wait for earlier invalidation.
.cloudKitContainer(...)iOS 18+Sync tip state, parameters, events, and display counts across devices.
MaxDisplayDurationiOS 18+Automatically invalidate after cumulative display time.
resetEligibility()iOS 26+Make a previously invalidated tip eligible again without resetting the datastore.

Configure TipKit

Call Tips.configure(_:) once during app initialization, before any tip can display. Do not configure TipKit from a view's onAppear or .task.

import SwiftUI
import TipKit

@main
struct MyApp: App {
    init() {
        do {
            try Tips.configure([
                .datastoreLocation(.applicationDefault),
                .displayFrequency(.daily)
            ])
        } catch {
            assertionFailure("TipKit configuration failed: \(error)")
        }
    }

    var body: some Scene {
        WindowGroup { ContentView() }
    }
}

Use .datastoreLocation(.groupContainer(identifier:)) only when an app and extension or app-group members intentionally share tip state. Keep option settings consistent across app-group members because TipKit persists option state with the tip record.

CloudKit Sync

Use CloudKit sync only on iOS 18+ and later. Enable iCloud + CloudKit and Background Modes > Remote notifications, then pass a container:

try Tips.configure([
    .cloudKitContainer(.named("iCloud.com.example.app.tips"))
])

Prefer a dedicated container with a .tips suffix. .automatic uses the first entitled .tips container when present, then falls back to the primary container.

Design Good Tips

Tips are small, transient help. Use them for features people can understand and try in a few simple steps. If the flow needs a long explanation, multiple screens, or critical safety/error information, use a tutorial, alert, inline warning, or onboarding flow instead.

Follow HIG-aligned defaults:

  • Keep titles short, direct, and action-oriented.
  • Use one or two sentences; avoid promotional or unrelated copy.
  • Place tips near the feature they explain.
  • Prefer inline tips when hiding nearby UI would interrupt the task.
  • Prefer popover tips when preserving the current layout matters and the tip can point to a specific control.
  • Use rules and display frequency so only the right audience sees each tip.
  • Avoid repeating an icon in the tip when the popover already points to that icon.

Define Tips

Tip conforms to Identifiable and Sendable. Provide title at minimum; add message, image, actions, rules, options, and id only when they improve the feature-discovery moment.

import TipKit

struct FavoriteTip: Tip {
    var title: Text { Text("Save to Favorites") }
    var message: Text? { Text("Tap the heart to keep items for quick access.") }
    var image: Image? { Image(systemName: "heart.fill") }
}

By default, TipKit uses the tip type name as id. Override id for reusable tips whose persisted state should vary by content:

struct NewItemTip: Tip {
    let itemID: Item.ID

    var id: String { "NewItemTip-\(itemID)" }
    var title: Text { Text("New Item Available") }
}

Use stable, concrete identifiers. Do not derive IDs from transient copy or unstable ordering.

Present Tips

Use TipView for inline tips:

let favoriteTip = FavoriteTip()

VStack {
    TipView(favoriteTip, arrowEdge: .bottom)
    ItemListView()
}

Use .popoverTip when the tip should point to a control:

Button {
    toggleFavorite()
    favoriteTip.invalidate(reason: .actionPerformed)
} label: {
    Image(systemName: "heart")
}
.popoverTip(favoriteTip, arrowEdge: .top)

Rules and Events

Rules are ANDed together. A tip becomes eligible only when every rule passes.

Use @Parameter for persisted app state:

struct FavoriteTip: Tip {
    @Parameter static var hasSeenList = false

    var title: Text { Text("Save to Favorites") }

    var rules: [Rule] {
        #Rule(Self.$hasSeenList) { $0 == true }
    }
}

Use Tips.Event for repeated user actions. TipKit queries the most recent 1000 donations by default, so keep event rules bounded and intentional.

struct ShortcutTip: Tip {
    static let manualSaveEvent = Tips.Event(id: "manualSave")

    var title: Text { Text("Save Faster") }

    var rules: [Rule] {
        #Rule(Self.manualSaveEvent) {
            $0.donations.donatedWithin(.week).count >= 3
        }
    }
}

ShortcutTip.manualSaveEvent.sendDonation()

For richer event rules, define Tips.Event<DonationInfo> where DonationInfo: Codable, Sendable. Keep donation payloads small.

Group related event definitions in a shared namespace when several tips use the same events; event IDs are the persistence boundary, so collisions can create confusing eligibility.

Options and Invalidation

Use options sparingly; frequency and invalidation rules are part of the tip's persisted behavior.

struct DailyTip: Tip {
    var title: Text { Text("Try Filters") }

    var options: [any TipOption] {
        MaxDisplayCount(3)
        IgnoresDisplayFrequency(false)
    }
}

MaxDisplayDuration is iOS 18+. It counts cumulative display time and has a minimum continuous display duration before automatic invalidation can occur. Do not use it as a replacement for explicit invalidate(reason:) when the app knows the taught action or ordered step is complete.

Call invalidate(reason:) when the user performs the discovered action or the tip is no longer relevant. Invalidation is permanent until the datastore is reset or, on iOS 26+, the specific tip calls await resetEligibility().

favoriteTip.invalidate(reason: .actionPerformed)

Use .tipClosed for explicit dismissal and .displayCountExceeded or .displayDurationExceeded only when describing automatic invalidation outcomes.

Actions and Styles

Add Action buttons when the user needs a direct route to settings, more information, or a setup flow.

struct FeatureTip: Tip {
    var title: Text { Text("Try the New Editor") }

    var actions: [Action] {
        Action(id: "open-editor", title: "Open Editor")
        Action(id: "learn-more", title: "Learn More")
    }
}

TipView(FeatureTip()) { action in
    switch action.id {
    case "open-editor":
        openEditor()
    case "learn-more":
        showHelp()
    default:
        break
    }
}

For custom appearance, prefer TipViewStyle.Configuration values over reading directly from a concrete tip instance. That preserves labels, handlers, and modifiers applied to the TipView.

struct CompactTipStyle: TipViewStyle {
    func makeBody(configuration: Configuration) -> some View {
        HStack(alignment: .top) {
            configuration.image?
            VStack(alignment: .leading) {
                configuration.title?
                configuration.message?
                ForEach(configuration.actions) { action in
                    Button(action: action.handler) {
                        action.label()
                    }
                }
            }
        }
        .padding()
    }
}

Tip Groups

TipGroup is iOS 18+. Store groups in SwiftUI state so the observable group object persists across view updates. In every review of a TipGroup(.ordered) plan, explicitly distinguish the default priority from ordered sequences: TipGroup defaults to .firstAvailable, and TipGroup(.ordered) is required when each later tip must wait for all previous tips to be invalidated.

struct OnboardingView: View {
    @State private var tips = TipGroup(.ordered) {
        WelcomeTip()
        SearchTip()
        FilterTip()
    }

    var body: some View {
        VStack {
            TipView(tips.currentTip)
            ContentView()
        }
    }
}

TipGroup defaults to .firstAvailable, which shows the first eligible tip in the group. Use .ordered only for true sequences, and invalidate each taught step when the user completes it so the next ordered tip can advance. MaxDisplayDuration can cap display time, but it is not the sequencing mechanism for an ordered group. Cast currentTip when the same group spans multiple controls:

Button("Search") { openSearch() }
    .popoverTip(tips.currentTip as? SearchTip)

Testing

Use testing overrides only in debug/test code, and apply them before Tips.configure(_:).

#if DEBUG
if ProcessInfo.processInfo.arguments.contains("--reset-tips") {
    try? Tips.resetDatastore()
}
if ProcessInfo.processInfo.arguments.contains("--show-all-tips") {
    Tips.showAllTipsForTesting()
}
#endif

try Tips.configure()

Built-in launch arguments are also available:

  • -com.apple.TipKit.ResetDatastore 1
  • -com.apple.TipKit.ShowAllTips 1
  • -com.apple.TipKit.ShowTips TipTypeA,TipTypeB
  • -com.apple.TipKit.HideAllTips 1

Testing override precedence is specific show, specific hide, show all, then hide all. Tips.resetDatastore() must run before Tips.configure(_:).

Common Mistakes

DON'T: Configure TipKit from a view

Configure during app initialization. View-level configuration can race with tip display and can also hit datastore-already-configured errors.

DON'T: Present iOS 18+ APIs as iOS 17 guidance

Gate TipGroup, CloudKit sync, and MaxDisplayDuration. Provide iOS 17 fallbacks with parameters/events only when the app still supports iOS 17. When the plan mentions TipGroup(.ordered), also call out that plain TipGroup defaults to .firstAvailable. Use this explicit review wording: "Plain TipGroup defaults to .firstAvailable; TipGroup(.ordered) is the iOS 18+ sequence mode where later tips wait for earlier invalidation."

DON'T: Use tips for critical information

Tips are dismissible and educational. Use alerts, confirmations, inline warnings, or blocking UI for safety, errors, data loss, and required steps.

DON'T: Ship testing overrides

showAllTipsForTesting() and related overrides bypass rules and frequency limits. Keep them behind #if DEBUG, test scheme arguments, or UI-test-only launch arguments.

DON'T: Use unstable reusable tip IDs

Tip IDs own persistence. If a reusable tip's ID changes unexpectedly, users can see duplicate or stale education.

Review Checklist

  • Tips.configure(_:) runs once during app initialization before tips display.
  • Tips.resetDatastore() runs only before configuration and only for tests/debug.
  • iOS 18+ and iOS 26+ TipKit APIs have availability gates or fallback guidance.
  • Tip copy is short, contextual, actionable, and not promotional.
  • Inline vs popover presentation matches the surrounding UI flow.
  • Rules target the intended audience and do not show every tip on first launch.
  • Event IDs are stable, namespaced when shared, and donation payloads are small.
  • Reusable tips override id with stable content-derived values.
  • Tips invalidate when the user performs the taught action.
  • TipGroup is stored in @State; reviews call out the default .firstAvailable priority and use .ordered only for true sequences with explicit invalidation, not MaxDisplayDuration as the sequencing mechanism.
  • CloudKit sync uses iCloud + CloudKit, Remote notifications, and a dedicated container when appropriate.
  • Custom styles use configuration values and call action.label().
  • Testing overrides are debug/test-only and never ship active in production.
