tracelet_ios 1.3.6

iOS implementation of the Tracelet background geolocation plugin.

1.3.6

• FIX: getLocations() now honors SQLQuery.start and SQLQuery.end timestamp filtering.
• FIX: getCount() now accepts optional SQLQuery for time-bounded counting.
• CHORE: Update cross-package dependency constraints to ^1.3.6.

1.3.5

• FIX: Fix Unable to find module dependency: 'TraceletCore' Swift compiler error by consolidating SPM targets into a single module and removing invalid cross-module imports.
• FIX: Add missing AVFoundation, AudioToolbox, and Network framework linker settings in Package.swift.

1.3.4

• CHORE: Update tracelet_platform_interface dependency constraint to ^1.3.3.

1.3.3

• FIX: Bundle TraceletCore Swift source files directly inside the plugin package instead of depending on an unpublished local CocoaPod. Fixes unresolved import TraceletCore when installed from pub.dev.

1.3.2

• PERF: Replace Foundation UUID() with C-level uuid_generate_random/uuid_unparse_lower in LocationEngine and TraceletDatabase (I-M6).

1.3.1

• FIX: getPersistenceExtras() now reads distinct persistenceExtras config key with backward-compatible fallback.
• PERF: markSynced() uses chunked SQL statements (500 UUIDs/chunk) instead of unbounded placeholder lists.

1.3.0

• FIX: getState() always returned enabled: false on iOS — StateManager.toMap() flat-merged the config dictionary into the state dictionary, causing config keys (enabled from audit section, isMoving from motion section) to overwrite runtime state values. Config is now correctly nested under a "config" key, matching the Android implementation and the Dart State.fromMap() contract (#26).

1.2.1

iOS↔Android Parity Fixes

• FEAT: Add ConfigManager.hasConfig() — returns true if a config has been persisted at least once (checks UserDefaults for stored config data). Matches existing Android ConfigManager.hasConfig().
• FEAT: Add StateManager.lastPeriodicLatitude / lastPeriodicLongitude — persisted coordinates for odometer computation across periodic tracking restarts. Returns NaN when no fix has been recorded; setting NaN removes the persisted value. Matches Android StateManager.lastPeriodicLatitude/Longitude.
• FEAT: Add StateManager.addOdometer(distance:) — incremental odometer accumulation method. Matches Android StateManager.addOdometer(distance).
• FEAT: Add LocationEngine.stopAllWatchers() — clears all active watch-position subscriptions. Called automatically from destroy(). Matches Android LocationEngine.stopAllWatchers().
• FEAT: Add TraceletEventSending.hasListener(eventName:) protocol method and EventDispatcher.hasListener(eventName:) implementation — checks if a Dart listener is attached for a given event channel. Accepts both full path (com.tracelet/events/location) and short name (location). Matches Android EventSender.hasListener().
• REFACTOR: All TraceletCore members made public for cross-module access with use_frameworks! CocoaPods integration.

1.2.0

• CHORE: Version bump for federation consistency with tracelet_platform_interface 1.2.0 (new NotificationPriority and HashAlgorithm enums).

1.1.0

New Features

• FEAT: Add native DeltaEncoder (Swift) for delta-compressed HTTP sync payloads — mirrors the Dart implementation exactly for platform consistency. Encodes only field deltas between consecutive locations using shortened keys (la, lo, t, s, h, a, al, b), achieving 60–80% bandwidth reduction. Uses Foundation's ISO8601DateFormatter with fractional seconds fallback for robust timestamp handling.
• FEAT: ConfigManager now reads and applies the following new configuration fields from Dart: batteryBudgetPerHour (adaptive battery budget target), enableSparseUpdates, sparseDistanceThreshold, sparseMaxIdleSeconds (app-level deduplication), enableDeadReckoning, deadReckoningActivationDelay, deadReckoningMaxDuration (inertial navigation when GPS lost), enableDeltaCompression, deltaCoordinatePrecision (HTTP delta encoding), and disableAutoSyncOnCellular (WiFi-only sync).
• FEAT: HttpSyncManager now supports disableAutoSyncOnCellular — skips auto-sync when device is on cellular network, syncing only on WiFi. Also conditionally applies DeltaEncoder.encode() to multi-location batches before HTTP upload when enableDeltaCompression is enabled, reducing upload size by 60–80%.

1.0.2

• FIX: handleReset() unconditionally removed geofence registrations from CLLocationManager even when stopOnTerminate: false was configured with trackingMode=1 (geofence mode). Geofences now survive the reset call so CLLocationManager continues monitoring regions after app termination (#23).

1.0.1

• FIX: HTTP auto-sync never triggered from automatic location tracking — onLocationInserted() was only called from the manual insertLocation handler, not from LocationEngine.persistLocationIfAllowed() (#21).
• FIX: ConfigManager.getHttpMethod() cast Int as String, silently ignoring HttpMethod.put — now correctly maps 0 → POST, 1 → PUT.
• FIX: ConfigManager.getHttpHeaders() strict [String: String] cast could drop headers when platform channel delivers [String: Any] — now coerces values to strings.
• FIX: maxBatchSize default corrected from 100 to 250 to match Dart and Android defaults.

1.0.0

🎉 Stable Release

• FEAT: First stable release of tracelet_ios.
• REFACTOR: Remove third-party company name references.
• All native iOS APIs are finalized and production-ready.

• CHORE: Add CoreLocation import to ConfigManager.swift for CLActivityType.

0.11.5

• FIX: Persist polygon geofence vertices to SQLite — add vertices TEXT column with PRAGMA table_info migration for existing installs, and JSON serialization/deserialization in insertGeofence()/geofenceRowToMap().
• FIX: Use NSNumber bridging for JSONSerialization vertex deserialization (fixes silent cast failure with [[Double]]).
• FIX: Handle heterogeneous vertex arrays — skip non-array entries instead of failing the entire cast.
• TEST: Add XCTest tests for geofence vertices CRUD (11 tests covering round-trip, validation, edge cases).
• TEST: Add DB migration integration tests — column addition, data preservation, idempotency, multi-geofence migration, fresh install.

0.11.4

• FIX: Revert over-aggressive allowsBackgroundLocationUpdates and significant-location guards — When In Use permission now works correctly for foreground and background tracking. iOS enforces permission at the OS level; only the killed-state entry point (autoResumeTracking) requires Always authorization.

0.11.3

• FIX: Add .authorizedAlways guard to autoResumeTracking() — prevents "When In Use" permission from triggering tracking after app is relaunched from killed state via significant-location-change.
• FIX: Guard allowsBackgroundLocationUpdates in configureLocationManager() and performPeriodicFix() — only set to true when Always authorization is granted.

0.11.2

0.9.0

• FEAT: HTTP sync retry engine — configurable retry with exponential backoff for transient 5xx, 429, and timeout failures. Defers sync on connectivity loss via NWPathMonitor. Batch continuation loop.
• FEAT: Configurable motion sensitivity — MotionDetector reads shakeThreshold, stillThreshold, stillSampleCount from ConfigManager at runtime (auto-converts m/s² to g-force).
• CHORE: Bump tracelet_platform_interface to ^0.9.0.

0.8.3

• FEAT: Proximity-based geofence auto-load/unload — only geofences within geofenceProximityRadius are registered with CLLocationManager, sorted by distance, capped at 20 (iOS limit). Enables monitoring thousands of geofences.
• FEAT: GeofenceManager.updateProximity() — re-evaluates which geofences to monitor on every location update, dynamically swapping region registrations as the device moves.
• FEAT: geofencesChange event fires with on/off arrays when geofences are activated/deactivated from proximity monitoring.
• FEAT: maxMonitoredGeofences config respected — caps simultaneously monitored regions below the platform limit.

• FEAT: iOS 17+ CLBackgroundActivitySession support via BackgroundActivitySessionManager — extends background runtime for location-tracking apps.
• FEAT: iOS 18+ CLServiceSession support via ServiceSessionManager — maintains authorization state during background execution.
• PERF: Wrap LocationEngine.didUpdateLocations in background task — protects persist + dispatch chain from iOS suspension.
• PERF: Wrap HttpSyncManager.sync() in background task — protects entire HTTP upload + DB cleanup cycle.
• PERF: Wrap HeadlessRunner.dispatchEvent() engine boot in background task — ensures Dart engine starts fully before iOS reclaims resources.
• PERF: Wrap all TraceletIosPlugin lifecycle transitions (handleStop, handleReset, onStopRequested, handleScheduleStop, stopAfterElapsedTimer) in background tasks.
• FIX: preventSuspendManager.start() now called in startGeofences() — was missing, causing audio keep-alive to not activate in geofence-only mode.
• FIX: preventSuspendManager.stop() now called in all stop paths (reset, stopOnStationary, scheduleStop, stopAfterElapsed) — was only called in handleStop().
• FIX: setConfig() now toggles preventSuspendManager mid-session when preventSuspend changes.
• FIX: reset() now calls cancelStopAfterElapsedTimer() — was leaving stale timer running after reset.
• FIX: iOS 17+/18+ session managers wired into all lifecycle paths (start, stop, startGeofences, reset, scheduleStart/Stop, stopOnStationary, stopAfterElapsed).

0.8.0

• FEAT: OEM compatibility stubs — getSettingsHealth returns isAggressiveOem: false (iOS has no OEM power management issues), openOemSettings returns false.

• CHORE: Bump tracelet_platform_interface to ^0.8.0.

0.7.1

• DOCS: Add mock location detection feature to README with platform-specific detection details.
• CHORE: Bump tracelet_platform_interface to ^0.7.1.

0.7.0

• FEAT: Mock location detection — isLocationMock() uses CLLocationSourceInformation (iOS 15+) to detect simulated locations.
• FEAT: Heuristic mock detection (level 2) — timestamp drift check (> 10s between location timestamp and system time = suspicious).
• FEAT: buildLocationMap() includes mock flag and mockHeuristics metadata map (timestampDriftMs, platformFlagMock).

• CHORE: Bump tracelet_platform_interface to ^0.7.0.

0.6.1

• REFACTOR: Remove 6 dead ConfigManager methods for filtering migrated to Dart in 0.6.0 (getDisableElasticity, getElasticityMultiplier, getFilterPolicy, getMaxImpliedSpeed, getTrackingAccuracyThreshold, getUseKalmanFilter).

• CHORE: Bump tracelet_platform_interface to ^0.6.1.

0.6.0

• REFACTOR: Remove duplicate location filtering from LocationEngine.didUpdateLocations() — elasticity, distance filter, accuracy filter, and speed filter now handled by shared Dart LocationProcessor.

• CHORE: Bump tracelet_platform_interface to ^0.6.0.

0.5.5

• FIX: onSchedule event now sends full state map (via stateManager.toMap()) instead of partial ["state": "on", "enabled": true] — fixes State.fromMap() crash on schedule events.

0.5.4

• FIX: Heartbeat event now wraps location data in {"location": ...} to match HeartbeatEvent.fromMap() — fixes heartbeat always returning zero coordinates.
• FIX: Heartbeat falls back to last known location (via buildLocationMap()) when getCurrentPosition returns null.

0.5.3

• CHORE: Bump tracelet_platform_interface to ^0.5.3.

0.5.2

• FEAT: Accelerometer-only motion detection mode — when disableMotionActivityUpdates is true, uses CMMotionManager raw accelerometer for permission-free stationary↔moving detection (no NSMotionUsageDescription required).
• FEAT: getMotionAuthorizationStatus() / requestMotionPermission() return 3 (granted) immediately in accelerometer-only mode — no OS dialog shown.
• PERF: Reuse shared CMMotionManager instance for sensor queries instead of creating throwaway instances.
• FIX: Auto-fallback to accelerometer-only when CMMotionActivityManager.isActivityAvailable() returns false.

0.5.1

• DOCS: Rewrite README with proper description, setup guide link, and related packages table.

0.5.0

• CHORE: Bump tracelet_platform_interface to ^0.5.0.
• CHORE: Bump version to 0.5.0.

• FIX: Add CLAuthorizationStatus guard in getCurrentPosition() — returns nil if not authorized instead of hanging.
• FIX: Single-sample path now sets desiredAccuracy = kCLLocationAccuracyBest before requestLocation().
• BREAKING: Requires tracelet_platform_interface: ^0.3.0.

0.2.4

• Fix LICENSE file format for proper SPDX detection on pub.dev.
