ios – How to upload a post

When my image is uploaded to firebase theres a extra field a videourl is added and that allows a video to be uploaded when the user image post is fetch from firebase but when the video is uploaded, it is uploaded by itself with no imageurl fields

I am stuck on this code i am not understanding why the videourl is being uploaded correctly to firebase but not the image. I want my user to be able to select a image or video from their photo album using photospickeritem to upload their post separately How can i fix this code to make that happen ?

class UploadPostViewModel: NSObject, ObservableObject {

  @Published var didUploadPost = false
@Published var videos = [Video]()
@Published var profileImage: Image?
    @Published var selectedImage: PhotosPickerItem? {
        didSet { Task { await dataImage()
            
            Task { try await sendVideo() }
        }
            
        }
        
    }
    
    private var uiImage: UIImage?

 func uploadPost(caption: String) async throws {
        guard let uid = Auth.auth().currentUser?.uid else { return }
        
        var videoUrl: String? = nil
        if let items = selectedImage {
             let videoData = try await items.loadTransferable(type: Data.self)
            videoUrl = (try await VideoUploader.uploadVideo(withData: videoData!))
                
                
            
        }
            
            var imageUrl: String? = nil
        if let image = uiImage {
            imageUrl = try await ImageUploader.uploadImage(image: image , type: .post)
        }
            
            let post = Post(
                ownerUid: uid,
                text: text,
                videoUrl: videoUrl, likes: 0,
                replyCount: 23,
                imageUrl: imageUrl, timestamp: Timestamp()
            )
            
            try await PostService.uploadPost(post)
            self.didUploadPost = true
            
            
            
            
        
        
    }
    func dataImage() async {
        guard let item = selectedImage else { return }
        
        guard let data = try? await item.loadTransferable(type: Data.self) else { return }
        guard let uiImage = UIImage(data: data) else { return }
        self.uiImage = uiImage
        self.profileImage = Image(uiImage: uiImage)
    }
    func sendVideo() async throws {
        guard let item = selectedImage else {return}
        guard let videoData = try await item.loadTransferable(type: Data.self) else {return}
        guard let videoUrl = try await VideoUploader.uploadVideo(withData: videoData) else { return}
        try await Firestore.firestore().collection("videos").document().setData(["videoUrl": videoUrl])
    }
    func fetchVideos() async throws {
        let snapshot = try await Firestore.firestore().collection("videos").getDocuments()
        self.videos = snapshot.documents.compactMap({ try? $0.data(as: Video.self) })
        }
    }
