FlowLayout

A Swift library that provides a flexible flow layout. Arrange SwiftUI subviews in a "flow" style, wrapping items to the next line when necessary — similar to how text is arranged in a paragraph.

Features

• Dynamic Wrapping: Subviews automatically wrap to a new row when there’s no more room in the current row.
• Alignment Options: Supports different SwiftUI alignment options like leading, trailing, center, top, and bottom alignment.
• Adjustable Spacing: Configurable horizontal and vertical spacing between subviews.
• Fit Content: Optionally fit the layout’s width to the total width of the subviews, or use the parent's width as proposed by SwiftUI.

Usage

1. Add FlowLayout as a dependency in your Swift Package Manager project:

   .package(
       name: "FlowLayout",
       url: "https://github.com/krishkumar/FlowLayout.git",
       .upToNextMajor(from: "1.0.0")
   )

2. Import the FlowLayout module in your Swift code:

   import FlowLayout

3. Use FlowLayout in your SwiftUI code:

    struct ContentView: View {
    	@State var allCities = ["Dallas", "Austin", "New York", "Singapore", "London", "Houston", "Washington DC", "San Francisco"]
    	var body: some View {
    		HStack {
    			FlowLayout {
    				ForEach(allCities, id: \.self) { city in
    					Text("\(city)")
    						.padding()
    						.background(Capsule().fill(.blue))
    				}
    			}
    		}
    	}
    }

Contributions are welcome! Feel free to open issues and submit pull requests.

Implementation

FlowLayout uses SwiftUI’s PreferenceKeys to measure child views, making it easier to adapt dynamically to changes in content size. Combined with SwiftUI’s Layout protocol — flexibly arrange subviews that automatically reflows as needed.
