SOLVED: Day 77 - Help storing image as Data in struct

Forums > 100 Days of SwiftUI

I'm attempting to store a name and image data into a struct of people for the Day 77 milestone project, and getting an error stating:

Value of optional type 'Data?' must be unwrapped to a value of type 'Data'

I'm sure I'm missing something obvious, but can't seem to put my brain on exacty why I can't load the UIImage data into the "people" array from the viewModel.

Thanks for any pointers!

The Struct is as follows:

struct SpecificPerson: Identifiable {
    var id = UUID()
    var name: String
    var image: Data?

    init(id: UUID, name: String, image: Data) {
        self.id = id
        self.name = name
        self.image = image

The AddPersonView is:

struct AddPersonView: View {
    @Environment(\.dismiss) var dismiss

    @State private var pickerItem: PhotosPickerItem?
    @State private var selectedImage: Image?
    @State private var uiSelectedImage: Data?

    @State private var selectedImageName: String = ""

    @Bindable var viewModel: PeopleViewModel

    var body: some View {
        VStack {
            if let selectedImage {

                Text("Please enter a name for this person:")
                TextField("Enter Name", text: $selectedImageName)

                Button("Save") {
                    let personToAdd = SpecificPerson(id: UUID(), name: selectedImageName, image: uiSelectedImage)
            } else {
                PhotosPicker("Select a Photo", selection: $pickerItem, matching: .images)
        .onChange(of: pickerItem) {
            Task {
                if let data = try await pickerItem?.loadTransferable(type: Data.self) {
                    uiSelectedImage = data

And the viewModel:

class PeopleViewModel {
    var people = [SpecificPerson]()


It's because in this line:

let personToAdd = SpecificPerson(id: UUID(), name: selectedImageName, image: uiSelectedImage)

you are supplying uiSelectedImage for the third parameter. uiSelectedImage is of type Data? but the signature of SpecificPerson.init calls for Data:

init(id: UUID, name: String, image: Data)

So you should be calling it with uiSelectedImage unwrapped. How exactly you do that (e.g., force unwrap, nil coalescing with a default value, etc) depends on how you want it to work in the event that uiSelectedImage is nil.
