A lightweight, modern Swift async/await timer/debounce/throttle implementation for Apple platforms.

• ✅ Swift Concurrency - Built with Swift's modern concurrency model using async/await and actors
• ✅ Thread Safety - Actor-based design ensures thread-safe operation
• ✅ Lightweight - Zero dependencies, minimal footprint
• ✅ Timer Utilities - Built-in AsyncTimer with support for one-time and repeating timers with configurable intervals
• ✅ Debounce Utilities - Built-in AsyncDebouncer with configurable debounce time
• ✅ Throttle Utilities - Built-in AsyncThrottler with leading/trailing and drift/anti-drift cadence

• Swift 5.10+ / Swift 6.0
• iOS 13.0+
• macOS 10.15+

Add AsyncTimer to your project using Swift Package Manager by adding it to your Package.swift file's dependencies:

dependencies: [
 .package(url: "https://github.com/codingiran/AsyncTimer.git", from: "0.0.7")
]

Or add it directly in Xcode:

1. Go to File > Add Packages...
2. Enter the repository URL: https://github.com/codingiran/AsyncTimer.git
3. Select the version or branch you want to use

import AsyncTimer
// One-time
let once = AsyncTimer(interval: .seconds(1), repeating: false) {
 print("fire once")
}
await once.start()
// Repeating (fire immediately on start)
let repeating = AsyncTimer(interval: .seconds(0.5), repeating: true, firesImmediately: true) {
 print("tick")
}
await repeating.start()
// ... later
await repeating.stop()

import AsyncTimer
let throttler = AsyncThrottler(
 throttleTime: .seconds(0.2),
 behavior: .trailingOnly, // .leadingOnly / .leadingAndTrailing
 cadence: .antiDrift // .drift for rolling windows
)
// High-frequency calls → at most one execution per window
await throttler.call { print("work") }

import AsyncTimer
let debouncer = AsyncDebouncer(debounceTime: .seconds(0.2))
await debouncer.call { print("fire after quiet period") }
