How to pass UIImage between to 2 Views in SwifUI - swift

Question

I want to separate the views, and I created a struct view to get only the image to make the code more cleaner, please I want to ask how can I pass the selected image to the next view, to make the code more cleaner and Can use this struct view everywhere in the project.
I put in second view PickAPhoto() but I'm not sure how to get the data from it.
Many Thanks,
struct PickAPhoto: View {
#State var imgSelected: UIImage = UIImage(named: "addCameraImg")!
#State var showAddPhotoSheet = false
// phppicker begin
#State private var showPhotoSheet = false
// phppicker end
#State private var sourceType: UIImagePickerController.SourceType = .camera
#State var image: Image? = nil
var body: some View {
Image(uiImage: imgSelected)
.resizable()
.cornerRadius(4)
// .frame(width: 200 , height: 200)
.padding(.top)
.aspectRatio(contentMode: .fit)
.frame(maxWidth: 200, maxHeight: 200)
.transition(.slide)
HStack {
Spacer()
Button(action: {showAddPhotoSheet.toggle()}) {
Label("Take a photo", systemImage: "camera")
.foregroundColor(Color("BrandPrimary"))
}
.sheet(isPresented: $showAddPhotoSheet){
ImagePicker(imageSelected: $imgSelected, sourceType: $sourceType)
// ImageViewPicker()
}
Button(action: { showPhotoSheet = true }) {
Label("Choose photo", systemImage: "photo.fill")
.foregroundColor(Color("BrandPrimary"))
}
.fullScreenCover(isPresented: $showPhotoSheet) {
PhotoPicker(filter: .images, limit: 1) { results in
PhotoPicker.convertToUIImageArray(fromResults: results) { (imagesOrNil, errorOrNil) in
if let error = errorOrNil {
print(error)
}
if let images = imagesOrNil {
if let first = images.first {
print(first)
// image = first
imgSelected = first
}
}
}
}
.edgesIgnoringSafeArea(.all)
}
Spacer()
}
}
}
struct SecondVIew: View {
var body: some View {
PickAPhoto()
}
func getImage(){
// I want to get the image here
}
}

Move the imgSelected source of truth state up in the View hierarchy and pass a write-access binding down.
struct SecondVIew: View {
#State var imgSelected: UIImage = UIImage(named: "addCameraImg")!
var body: some View {
PickAPhoto(imgSelected: $imgSelected)
}
}
struct PickAPhoto: View {
#Binding var imgSelected: UIImage
