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 4 project/configuration file(s) and 15 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 Declared Age Range.

Ownership and state

classDiagram
    AgeAssuranceAndPermissionsApp *-- ComplianceManager : complianceManager
    AgeAssuranceAndPermissionsApp *-- SignificantChangeVersionManager : versionManager
    AgeAssuranceAndPermissionsApp *-- Logger : logger
    ComplianceManager *-- Bool : isComplianceRequired

Ownership evidence

AgeAssuranceAndPermissions/AgeAssuranceAndPermissionsApp.swift:14 — stored dependency or nearest verified ownership anchor

    @State private var complianceManager = ComplianceManager()

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

AgeAssuranceAndPermissions/AgeAssuranceAndPermissionsApp.swift:13 — representative type boundary

struct AgeAssuranceAndPermissionsApp: App {
    // ...
}

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

Access control

Reference code

AgeAssuranceAndPermissions/AgeAssuranceAndPermissionsApp.swift:14 — representative boundary

    @State private var complianceManager = ComplianceManager()

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: AgeAssuranceAndPermissionsApp; Manager: ComplianceManager, SignificantChangeVersionManager; View: ContentView, ImageView, MapView, RequestParentalApprovalView, SignificantChangeInformationView.
• Protocols: no local protocol declaration in the scanned source.
• Methods: identifyRegulatoryRequirements, textStyle, synchronize, handleAllChanges, handlePendingChanges.
• Files: AgeAssuranceAndPermissions/AgeAssuranceAndPermissionsApp.swift, AgeAssuranceAndPermissions/ComplianceManager.swift, AgeAssuranceAndPermissions/ContentView.swift, AgeAssuranceAndPermissions/ImageView.swift, AgeAssuranceAndPermissions/MapView.swift, AgeAssuranceAndPermissions/RequestParentalApprovalView.swift.

Architecture takeaways

• AgeAssuranceAndPermissionsApp is the main source-visible entry or composition anchor for this sample.
• Framework work reaches SwiftUI, DeclaredAgeRange, PermissionKit, AVKit 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.
