The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding DGImageCropper as a dependency is as easy as adding it to the dependencies value of your Package.swift or the Package list in Xcode.

dependencies: [
   .package(url: "https://github.com/donggyushin/DGImageCropper", .upToNextMajor(from: "1.0.1"))
]

Normally you'll want to depend on the DGImageCropper target:

.product(name: "DGImageCropper", package: "DGImageCropper")

    @State private var image: UIImage?
    @State private var degree: Double = 0
    
    init() {
        let model: ImageCropperModel = .init(image: .sample)
        self.model = model
    }
    
    var body: some View {
        VStack {
            
            DGImageCropper(model: model)
            
            HStack {
                Button("1:1") {
                    model.changeRatio(ratio: .square)
                }

                    model.changeRatio(ratio: .width4height3)
                }

                    model.changeRatio(ratio: .width3height4)
                }

            .padding()
        }
