Architecture

SwiftUI + MVVM, targeting iOS 26. Key technology choices:

Concern	Solution
Persistence	SwiftData (@Model)
Networking	URLSession async/await
State / ViewModels	@Observable + @MainActor
App entry point	@main JavaZoneApp: App
Notifications	UNUserNotificationCenter async/await

Build & Run

Open JavaZone.xcodeproj in Xcode and run, or from the command line:

xcodebuild -project JavaZone.xcodeproj -scheme JavaZone \
  -destination 'platform=iOS Simulator,name=iPhone 15'

Debug flags

Flag	Effect
DEBUG	25% chance of auto-refresh on launch (set automatically in Debug config)
TESTNOTIFICATIONS	Notification fires 15 s after favouriting instead of 7 min before session

---

Testing

# Via Fastlane
bundle exec fastlane ios unittest

# Direct
xcodebuild test -project JavaZone.xcodeproj -scheme JavaZone \
  -destination 'platform=iOS Simulator,name=iPhone 15'

Tests live in JavaZoneTests/ — String+UtilsTest.swift and Date+UtilsTest.swift.

---

Deployment

Deployment is handled by Fastlane. Requires a .env file (not committed) with:

APPLE_ID=<your Apple ID>
FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD=<app-specific password from appleid.apple.com>
SLACK_URL=<webhook URL for the app Slack channel>

Lane	Command	Description
unittest	bundle exec fastlane ios unittest	Run unit tests
gitprep	bundle exec fastlane ios gitprep	Increment build number, commit, tag, push
beta	bundle exec fastlane ios beta	Sign, build, upload to TestFlight
release	bundle exec fastlane ios release	Sign, build, upload to App Store

beta and release call gitprep and codesignprep automatically.

---

Configuration

JavaZone/EnvConfig.xcconfig is read at build time and injects values into Info.plist:

PARTNER_URL = javazone.no/partner

AppConfig (persisted in UserDefaults) is seeded from the remote config endpoint on first launch and updated on each session refresh.
