A modular Swift 6 toolkit of concurrency helpers, Foundation extensions, SwiftUI / UIKit / AppKit components, and focused utilities (Money, MediaPlayer, IAP, Camera, Exif, property wrappers, …) — all compiled under strict concurrency.

At a glance

import PovioKitAsync
import PovioKitUtilities

// Retry a flaky network call with exponential backoff + jitter.
let data = try await retry(
  policy: .init(
    maxAttempts: 3,
    initialDelay: .milliseconds(250),
    backoffFactor: 2,
    jitter: .milliseconds(100)
  )
) {
  try await api.fetchProfile()
}

// Bound an operation with a timeout.
let result = try await withTimeout(.seconds(2)) {
  try await heavyWork()
}

// Typed money, no silent currency mixing.
let usd = Money(amount: 1_299, currency: .usd)
let eur = Money(amount:   999, currency: .eur)

try usd + usd    // OK
try usd + eur    // throws Money.ArithmeticError.currencyMismatch

Migration

Please read the Migration document.

Documentation

API documentation is generated with DocC and published through GitHub Pages at povio.github.io/PovioKit. Per-module entry points:

• PovioKitCore
• PovioKitUtilities
• PovioKitAsync
• PovioKitUIKit

Contributing

Contributions are very welcome.

• Run the full test suite locally with swift test, or open Package.swift in Xcode and use the PovioKit-Package scheme.
• CI builds the package against the declared minimum deployment targets (iOS 17 / macOS 14) on every pull request, in addition to the current Xcode default simulator.
• For substantial API changes, please open an issue first so we can discuss the shape before you invest time.
