Add blur effect mask to your SwiftUI views.

Highly based on VariableBlur by @nikstar

Changes in this version:

• Removed gradient blur capability - no more directional blur transitions from VariableBlur
• Simplified to uniform blur only - consistent blur intensity across entire masked area
• Streamlined API - reduced from complex parameters (direction, startOffset) to simple radius control
• Eliminated gradient mask generation - no more CIFilter.linearGradient() calculations for better performance

🟡 Uses private APIs like VariableBlur - potential App Store rejection risk.

Copy BlurMask.swift to your project.

// Basic
BlurMask()                // Default radius: 24
BlurMask(blurRadius: 12)  // custom radius

// View modifier
view.blurMask(radius: 24)

// Navigation bar with blur example
ZStack(alignment: .top) {
  ScrollView {
    // Some content
    }
    .padding(.top, navBarHeight)
  }
  Text("Nav Bar")
    .frame(height: navBarHeight)
    .background(
      BlurMask()
        .ignoresSafeArea(edges: .top)
    )
}
