To run the example project, clone the repo, and run.

CropImageView is a swift package.
- It can be imported into an app project using Xcode’s new Swift Packages option, which is located in the File menu.

Alternatively, if you're unable to use SPM for some reason, you can import it manually.
Add CropImageView.swift to your project.
var inputImage: UIImage {
return UIImage(named: "demo") ?? UIImage(systemName: "sun.haze.fill")!
}
var body: some View {
VStack {
Button(action: {
self.showCropView = true
}) {
Text("Show the crop view")
}
if self.croppedImage != nil {
Image(uiImage: self.cropedImage!)
.resizable()
.scaledToFit()
.padding()
}
}
.sheet(isPresented: $showCropView,onDismiss:finishedCrop ) {
CropImageView(inputImage: self.inputImage, resultImage: self.$croppedImage, cropSize: CGSize(width: 250, height: 250))
}
}
