Pull Request: SwiftUI Modernization, Core Models, & Live Activities

Overview

This pull request continues the comprehensive modernization of the SimRa iOS application by migrating core Objective-C data models, region managers, and upload systems completely to Swift, while introducing robust Live Activity support, modern SwiftUI navigation structures, updated Bluetooth components, deep iOS system integration, and a redesigned App Icon adhering to the latest Apple design guidelines.

Key Changes & Component Breakdown

1. Model Modernization & Swift Porting

Replaced legacy .h/.m implementation pairs with native Swift classes utilizing @objcMembers to ensure seamless interoperability with remaining Objective-C modules.

• News.swift: Reimplemented news fetching and version parsing logic, handling network requests via URLSession, response evaluation, and local version persistence.
• Region.swift & Regions.swift: Converted region management, localization helpers, coordinate handling, and distance calculations into clean Swift, leveraging JSON dataset parsing with safe fallbacks to legacy plist structures.
• Trip.swift & Related Models: Completely transitioned the heavy trip data layer (Trip.swift, TripModels.swift) from Objective-C to modern Swift structures to improve memory safety and performance during route processing.
• UploaderObject.swift: Modernized data upload routines, handling multipart/file uploads via URLSession and secure SSL certificate pinning through the Security framework (SecTrustEvaluateWithError).
• IdPicker.swift: Added a clean SwiftUI component for selection workflows.

2. SwiftUI Views & Architecture Modernization

• Application Entry (SimRaApp.swift): Migrated the app initialization to the modern SwiftUI @main lifecycle model, integrating WindowGroup, AppDelegate bridging, and custom URL scheme handling (simra://) for deep links.
• OpenBikeSensor Integration (OBSConfigView.swift & ViewModel): Rewrote the Bluetooth configuration module using a @MainActor-isolated ObservableObject and a reactive CoreBluetooth wrapper to handle asynchronous peripheral discovery and telemetry displays.
• Floating Action Button (ModernRecordActionButton.swift): Introduced a custom recording action button with advanced SwiftUI styling, spring animations, and native accessibility traits.
• Interactive Hazard Map (SimRaHazardMapView.swift): Embedded the web-based SimRa hazard map via a performant UIViewRepresentable wrapper around WKWebView with custom navigation delegation.
• Trip Management & Settings (TripDetailView.swift & TripSettingsView.swift): Converted table layouts into native SwiftUI Form structures supporting unsaved changes tracking via .onChange and persistent preferences via @AppStorage.

3. Live Activity & Dynamic Island Integration (SimRaRecordingActivityManager.swift)

Introduced full support for iOS 16.2+ Live Activities via ActivityKit to display real-time trip metrics on the Lock Screen and Dynamic Island.

• Lifecycle Management: Manages creation, updating, and immediate dismissal policies for recording sessions (SimRaRecordingAttributes).
• Route & Hazard Extensions: Added specialized activity updaters (SimRaRecordingActivityManager+Enhanced.swift) to dynamically push live route coordinate buffers and increment recorded hazard counters during active bike rides.

4. Utility Extensions & Charting Modules

• DSBarChart: Replaced legacy Quartz-based charting with a lightweight SwiftUI bar chart component featuring automatic data scaling and conditional color gradient rendering.
• String Hashing (NSString+hashCode.swift): Implements a Swift extension replicating Java/Objective-C UTF-16 string hashing algorithms for consistent backend client identifier generation.
• Time Formatting (NSTimeInterval+hms.swift): Adds clean formatting extensions to TimeInterval for structured human-readable duration outputs.

Technical Notes & Architectural Decisions

• Interoperability: Retained @objc and @objcMembers attributes on migrated model classes to prevent breaking integration points with existing legacy database controllers or delegates.
• Concurrency: Ensured thread safety for UI-bound live activity updates and Bluetooth stack communication by annotating managers with @MainActor and leveraging async/await.
