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 5 project/configuration file(s) and 36 source declaration(s).

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 TabletopKit.

Ownership and state

classDiagram
    ResetPlayer o-- EquipmentIdentifier : playerId
    ResetPlayer *-- Int : seat
    FreezePlayer o-- EquipmentIdentifier : playerId
    ActivatePlayer o-- EquipmentIdentifier : playerId

Ownership evidence

TabletopKit Mini-Game/TabletopKit Mini-Game/CustomAction.swift:11 — stored dependency or nearest verified ownership anchor

struct ResetPlayer: CustomAction {
    var playerId: EquipmentIdentifier
    // ...
}

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

TabletopKit Mini-Game/TabletopKit Mini-Game/TabletopKitMini-GameApp.swift:17 — representative type boundary

struct MiniGameApp: App {
    // ...
}

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

Access control

Reference code

TabletopKit Mini-Game/Packages/RealityKitContent/Sources/RealityKitContent/RealityKitContent.swift:10 — representative boundary

public let realityKitContentBundle = Bundle.module

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: App: MiniGameApp; Manager: GroupActivityManager; Observer: GameObserver; Player: ActivatePlayer, FreezePlayer, Player, ResetPlayer; Renderer: GameRenderer; View: GameView.
• Protocols: no local protocol declaration in the scanned source.
• Methods: apply, playerID, aimingSightID, bankID, stoneID, lilyPadID, logID, coinID.
• Files: TabletopKit Mini-Game/TabletopKit Mini-Game/GroupActivityManager.swift, TabletopKit Mini-Game/TabletopKit Mini-Game/GameInteraction.swift, TabletopKit Mini-Game/TabletopKit Mini-Game/GameObserver.swift, TabletopKit Mini-Game/TabletopKit Mini-Game/GameRenderer.swift, TabletopKit Mini-Game/TabletopKit Mini-Game/Game.swift, TabletopKit Mini-Game/TabletopKit Mini-Game/GameSetup.swift.

Architecture takeaways

• TabletopKitMini-GameApp is the main source-visible entry or composition anchor for this sample.
• Framework work reaches TabletopKit, RealityKit, SwiftUI, Spatial 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.
