Native, Modern Key-Value Store for iOS & macOS.

A focused, Swift-native wrapper for Apple's UserDefaults (and filesystem). PolyKV brings a unified API to your Apple ecosystem apps, making cross-platform logic sharing a breeze.

One API, Everywhere. This library is part of the PolyKV ecosystem. Use the same consistent API across 12+ languages.

• 🍎 Apple Native Built directly on top of UserDefaults and FileManager. Zero external dependencies.

• 🧵 Structured Concurrency Designed for Swift's modern concurrency model. No more completion handler hell.

• 🛡 Sandboxed by Default Automatically respects Apple's App Sandbox rules, so your data is stored securely and compliantly.

Add this to your Package.swift:

dependencies: [
    .package(url: "https://github.com/your-username/polykv.git", from: "1.0.0")
]

import PolyKV

Task {
    let kv = PolyKV("MyApp")

    // 1. Save
    await kv.setString("username", "john_doe")
    await kv.setBool("notifications", true)
    await kv.setMap("flags", ["beta": true])

    // 2. Read
    if let user = await kv.getString("username") {
        print("User: \(user)")
    }

    // 3. Update
    await kv.setBool("notifications", false)

    // 4. Delete
    await kv.remove("flags")

    // 5. Clear All
    await kv.clear()
}

✅ Runtime Verified: Full CRUD operations verified via automated tests on actual devices/simulators.
