## What it is
PinLayout is a Swift layout library for laying out UIView, NSView, and CALayer without Auto Layout, using concise, chainable, pure-code syntax. It supports iOS, tvOS, and macOS and offers fast, fully controlled frame-based layouting.

## Use cases
- lay out iOS views in Swift without Auto Layout constraints
- replace storyboard constraints with readable chainable layout code
- position views relative to safe area or keyboard
- compute view sizes automatically with sizeToFit
- layout CALayer directly on macOS or iOS
- support right-to-left language layouts

## When to choose
- you want maximum layout performance without constraint solving
- you prefer explicit frame-based layout code over Auto Layout
- you need a lightweight layout DSL for iOS, tvOS, or macOS views

## When to avoid
- your project is heavily invested in Interface Builder and constraint-based Auto Layout
- you need reactive constraint updates that adapt automatically to size-class changes
- you are building for platforms outside Apple's ecosystem
