## What it is
Repeat is a lightweight Swift library providing a modern GCD-based alternative to NSTimer, with support for infinite, finite, and one-shot timers, multiple observers, and pause/resume control. It also includes a debouncer and throttler for rate-limiting function calls.

## Use cases
- replace NSTimer with a modern Swift timer
- schedule a task to run every N seconds in Swift
- debounce user input events in an iOS app
- throttle API calls to once per interval
- run a repeating timer on a background thread
- create a one-shot delayed action in Swift

## When to choose
- you need a timer without strong reference cycles or NSObject inheritance
- you want debounce/throttle utilities in Swift
- you need timers that work on background threads with multiple observers

## When to avoid
- you need a maintained library with recent updates (last release 2021)
- you're targeting platforms outside Apple's ecosystem
- you can use Combine or async/await timers in modern Swift instead
