Swiftui image not getting rendered in sharesheet - unless you click twice - swiftui

Question

I create a view that will become a snapshot to send to the Share Sheet. Unfortunately, I get a nil image the first time I click share. The second time, the snapshot image shows up fine.
struct AffirmationSharingView: View {
//saving this view to send to shareSheet
var viewToShare: some View {
ZStack{
Image("night4")
.resizable()
Text("affirmation here")
.foregroundColor(.white)
}
}
#State private var showShareSheet = false
#State var myImage: UIImage! = UIImage(named: "test")
var body: some View {
GeometryReader{gp in
ZStack{
Image("night4")
.resizable()
.frame(width: gp.size.width*0.9, height: gp.size.height*0.5 , alignment: .top)
Text("affirmation here")
Spacer()
HStack{
VStack{
Image("wigshareIcon")
.resizable()
.aspectRatio(1, contentMode:.fit)
.frame(width: gp.size.width*0.2, height: 60, alignment: .top)
Text("Share To Other Social Media")
}
.onTapGesture {
//save the image/affirmation combo to a UIImage to be sent to the share sheet
myImage = viewToShare.snapshot()
self.showShareSheet = true
}
}
.padding()
}
}
}
.onAppear(perform: getImage)
.sheet(isPresented: $showShareSheet, content: {
// let myImage3 = viewToShare.snapshot()
ShareView(activityItems: ["Rest Rise Grow App!",myImage]) //myImage!]) //[myImage as! Any]) //[data])
}
func getImage(){
self.myImage = viewToShare.snapshot()
if self.myImage != nil {
print("1sharesheet has some value")
print("1sharesheet equals \(myImage)")
} else {
print("Did not set 1screenshot")
}
}
extension View {
func snapshot() -> UIImage {
let controller = UIHostingController(rootView: self)
let view = controller.view
let targetSize = controller.view.intrinsicContentSize
view?.bounds = CGRect(origin: .zero, size: targetSize)
view?.backgroundColor = .clear
let renderer = UIGraphicsImageRenderer(size: targetSize)
return renderer.image { _ in
view?.drawHierarchy(in: controller.view.bounds, afterScreenUpdates: true)
}
}
}
Here are the logs:
