Structure observations

• Architecturally prominent files are ranked from entry points and role-named declarations; resource-only paths are omitted.
• Primary languages: Swift.
• The verified tree contains 7 project/configuration file(s) and 5 source declaration(s).

Reference code

Siri Event Suggestions/Siri Event Suggestions/AppDelegate.swift:16 — architecture anchor

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    // ...
}

Interpretation

The arrows summarize the source-visible entry, role-named types or folders, and framework direction; when nodes come from structural folders, the sequence is a high-level interpretation rather than proof that every adjacent node calls the next. Ownership is claimed only where the next section cites a stored property or assignment. The diagram is intentionally limited to the dominant path into Intents.

Ownership and state

classDiagram
    AppDelegate o-- Notification : showReservation
    AppDelegate o-- Notification : startReservationCheckIn
    AppDelegate o-- UIWindow : window
    ReservationContainersTableViewController o-- NSObjectProtocol : showReservationNotificationToken

Ownership evidence

Siri Event Suggestions/Siri Event Suggestions/AppDelegate.swift:12 — stored dependency or nearest verified ownership anchor

    static let showReservation = Notification.Name("ShowReservation")

Composition arrows indicate a source-visible construction expression or locally owned value state; aggregation means the owner stores or receives a dependency without proving exclusive lifetime ownership.

Class and protocol design

Siri Event Suggestions/Siri Event Suggestions/AppDelegate.swift:17 — representative type boundary

class AppDelegate: UIResponder, UIApplicationDelegate {
    // ...
}

No local protocol conformance is claimed as protocol-oriented design; external framework conformances are listed only as dependencies.

Access control

Reference code

Siri Event Suggestions/Siri Event Suggestions/HelperExtensions.swift:12 — representative boundary

    open override func present(
        _ viewControllerToPresent: UIViewController,
        animated flag: Bool,
        completion: (() -> Void)? = nil) {
        // ...
    }

Swift declarations without a modifier are internal; explicit private, fileprivate, private(set), public, or open entries above are interpreted by language semantics. Objective-C/C samples instead rely on header and implementation boundaries, which are not equivalent to Swift lexical privacy.

Logic ownership and placement

Design patterns

Naming conventions

• Types: Controller: ReservationContainersTableViewController, ReservationDetailsViewController, ReservationsTableViewController; Delegate: AppDelegate.
• Protocols: no local protocol declaration in the scanned source.
• Methods: application, viewDidLoad, buildTable, viewDidAppear, didPressClearButton, tableView, updateReservations, setupNotifications.
• Files: Siri Event Suggestions/Siri Event Suggestions/AppDelegate.swift, Siri Event Suggestions/Siri Event Suggestions/View Controllers/ReservationContainersTableViewController.swift, Siri Event Suggestions/Siri Event Suggestions/View Controllers/ReservationDetailsViewController.swift, Siri Event Suggestions/Siri Event Suggestions/View Controllers/ReservationsTableViewController.swift, Siri Event Suggestions/Siri Event Suggestions/Server.swift.

Architecture takeaways

• AppDelegate is the main source-visible entry or composition anchor for this sample.
• Framework work reaches Intents, UIKit, Contacts through a deliberately small high-level chain; the detailed API graph remains inside the cited implementation files.
• Stored-property evidence identifies lifecycle collaboration; it does not by itself prove exclusive object ownership.
• Access-control conclusions separate verified language visibility from the likely design rationale.
• The source does not justify labeling the design protocol-oriented.
