## What it is
FDStackView is an Objective-C library that lets iOS developers use UIStackView directly on iOS 6+ by transparently swapping in a compatible implementation at runtime on pre-iOS 9 devices. It requires no code changes or imports and supports Interface Builder with live preview.

## Use cases
- use UIStackView in apps supporting iOS 6-8
- backport stack views to older iOS versions
- build flow layouts without writing manual constraints
- use UIStackView in Interface Builder with live preview on older deployment targets
- migrate legacy iOS apps to stack view layouts

## When to choose
- you must support iOS versions below 9 and want stack view layout
- you want zero-code-change drop-in UIStackView compatibility
- you rely on Interface Builder stack view previews with an older deployment target

## When to avoid
- your deployment target is iOS 9 or later (use native UIStackView)
- you need an actively maintained library or Swift support
- you are starting a new project targeting modern iOS
