## What it is
Glur is a Swift package that adds progressive (graduated) blur effects to SwiftUI views via a .glur() modifier, implemented with custom Metal shaders and no private APIs. It also offers an optional GlurBackdrop product for blurring the content behind a view, targeting iOS 15+, macOS 12+, watchOS 8+, tvOS 15+, and visionOS.

## Use cases
- add a progressive blur effect to a SwiftUI view
- recreate Apple's graduated blur look without private APIs
- blur just the bottom edge of an image in an iOS app
- apply a variable blur with configurable radius, offset, direction, and noise
- blur the backdrop behind a floating UI element on macOS or iOS
- get efficient GPU-rendered blurs using Metal instead of CIFilter

## When to choose
- You are building a SwiftUI app on iOS 17+/macOS 14+/tvOS 17+ and want Apple-style progressive blurs using only public APIs
- You want a lightweight, MIT-licensed Swift package that integrates via Swift Package Manager
- You need fine control over blur radius, offset, interpolation, direction, and noise

## When to avoid
- You target watchOS in production, where the Metal implementation is unavailable and only a lower-quality compatibility effect runs
- Your production app must support pre-iOS 17 / pre-macOS 14 and the compatibility effect's quality is not acceptable
- Your codebase is UIKit/AppKit-only with no SwiftUI usage
