MyFAQ.app

Native iOS and Android client for phpMyFAQ, built with Kotlin Multiplatform, SwiftUI, and Jetpack Compose.

Status: Phase 0 (foundations). The apps display a placeholder screen that proves the shared module, API client, encrypted database, and secure storage are wired end-to-end. No user-visible features yet -- those land in Phase 1.

• Website: myfaq.app
• phpMyFAQ minimum version: 4.2.0
• Business model: freemium (read + offline free forever; writes behind Pro unlock in Phase 3)

Prerequisites

Tool	Minimum	Install
JDK	17+	brew install openjdk or Temurin
Android SDK	API 35	Android Studio or sdkmanager
Xcode	15.0	Mac App Store (macOS only)
XcodeGen	latest	brew install xcodegen
Git	2.x	pre-installed on macOS

Run the bootstrap checker:

mobile/scripts/bootstrap.sh

Android SDK quick setup (without Android Studio)

brew install --cask android-commandlinetools
sdkmanager "platforms;android-35" "build-tools;35.0.0"
echo "sdk.dir=$HOME/Library/Android/sdk" > mobile/local.properties

Xcode first-launch setup

If you see xcodebuild errors about IDESimulatorFoundation:

sudo xcodebuild -runFirstLaunch
sudo xcodebuild -license accept

Building & running

Android

cd mobile
./gradlew :androidApp:assembleDebug

The debug APK lands at mobile/androidApp/build/outputs/apk/debug/androidApp-debug.apk.

Install on a connected device or emulator:

adb install androidApp/build/outputs/apk/debug/androidApp-debug.apk

Or open mobile/ as a project in Android Studio and run from the IDE.

iOS

# 1. Build the shared KMP framework
cd mobile
./gradlew :shared:assembleSharedDebugXCFramework

# 2. Generate the Xcode project (one-time, re-run after project.yml changes)
cd iosApp
xcodegen generate

# 3a. Open in Xcode and run (Cmd+R)
open iosApp.xcodeproj

# 3b. Or build from CLI
xcodebuild \
  -project iosApp.xcodeproj \
  -scheme iosApp \
  -configuration Debug \
  -destination 'platform=iOS Simulator,name=iPhone 16' \
  CODE_SIGNING_ALLOWED=NO \
  build

To run on a simulator from CLI after building:

xcrun simctl boot "iPhone 16" 2>/dev/null
xcrun simctl install booted \
  build/Build/Products/Debug-iphonesimulator/iosApp.app
xcrun simctl launch booted app.myfaq.ios

Note: After changing shared Kotlin code, rebuild the XCFramework (step 1) before rebuilding in Xcode. The pre-build script in project.yml does this automatically but adds build time. For faster iteration, disable it in Xcode's Build Phases and run the Gradle task manually.

Running tests

cd mobile

# Shared module tests (JVM — fast, no device/simulator needed)
./gradlew :shared:testDebugUnitTest

# Shared module iOS tests (requires macOS + Xcode)
./gradlew :shared:iosSimulatorArm64Test

# All shared tests
./gradlew :shared:allTests

What the tests cover (Phase 0)

Test file	What it validates
MyFaqApiTest	/meta deserialization, unknown-key tolerance, MetaLoader rendering
EntitlementsTest	Entitlements.isPro() always returns false
SecureStoreContract	Round-trip put/get/remove/clear (abstract; run by platform tests)

---

Tech stack

Layer	Technology
Shared logic	Kotlin Multiplatform
Android UI	Jetpack Compose, Material 3
iOS UI	SwiftUI
HTTP	Ktor (MockEngine in Phase 0; OkHttp/Darwin in Phase 1)
Serialization	kotlinx.serialization
Database	SQLDelight + SQLCipher (Android) / Data Protection (iOS)
Secure storage	EncryptedSharedPreferences (Android) / Keychain (iOS)
DI	Koin
API codegen	openapi-generator (Kotlin multiplatform target)

Pinned versions

See mobile/gradle/libs.versions.toml for the single source of truth. Key versions:

• Kotlin 2.1.20, Gradle 9.4.1, AGP 8.10.0
• Ktor 3.0.3, SQLDelight 2.0.2, Koin 4.0.0
• Android min SDK 26, iOS 16.0

Regenerating the API client

The Kotlin API client is generated from the pinned phpMyFAQ OpenAPI spec at mobile/spec/openapi/v3.2.yaml. To update:

# Download the spec from a phpMyFAQ release
curl -fsSL \
  https://raw.githubusercontent.com/thorsten/phpMyFAQ/4.2.0/docs/openapi.yaml \
  -o mobile/spec/openapi/v3.2.yaml

# Regenerate (requires openapi-generator-cli or Docker)
mobile/scripts/generate-api-client.sh

Or trigger the mobile-openapi-sync GitHub Actions workflow.
