SecureStorgageSample

A sample iOS app demonstrating the LocalData package capabilities for secure, typed storage across multiple domains.

Features

This app provides interactive demos for all LocalData storage options:

Tab	Demo	Storage Domain
Defaults	Save/load/remove values	UserDefaults
Keychain	Secure credentials with biometrics	Keychain
Files	User profiles with AnyCodable	File System
Encrypted	Encrypted logs (AES or ChaCha20)	Encrypted File System
Sync	Platform availability & sync policies	Multiple

The project also includes a watchOS companion app target for watch-specific demos.

Requirements

• iOS 17.0+
• watchOS 10.0+ (companion app target)
• Xcode 15+

Getting Started

1. Open SecureStorgageSample.xcodeproj
2. Select an iOS simulator or device
3. Build and run (⌘R)

Storage Key Examples

The app demonstrates various storage configurations:

UserDefaults

• Simple string storage with automatic sync
• Custom suite support

Keychain

• 7 accessibility options (whenUnlocked, afterFirstUnlock, etc.)
• 6 access control options (biometry, passcode, etc.)

File System

• Documents directory (persisted, backed up)
• Caches directory (can be purged)
• JSON and PropertyList serializers

Encrypted Storage

• AES-256-GCM or ChaCha20-Poly1305 encryption
• PBKDF2 or HKDF key derivation
• Complete file protection

Platform & Sync

• Platform availability (phoneOnly, watchOnly, all)
• Sync policies (never, manual, automaticSmall)

Dependencies
