我正在尝试创建一个小型社交媒体应用程序。到目前为止一切工作正常，但是当我试图显示 an 的长度（这保存了 a中Array的朋友）时，我收到错误UserProfilView"No exact matches in call to initializer"

Capsule()
    .frame(width: 110, height: 30)
    .offset(x: 40)
    .foregroundColor(.blue)
    .overlay(
        HStack {
            Image(systemName: "person.3.fill")
                .foregroundColor(.white)
                .position(x: 120, y: 15)
            Text(appUser.friends.count)
                .foregroundColor(.white)
                .position(x: 35, y: 15)
                .frame(width: 70, height: 30, alignment: .trailing)
        }
    )

我正在取消 UiKit 图像选择器并尝试为用户设置个人资料图片。一切正常，图像显示出来。但我正在努力将其变成一个圆圈。我尝试将 ClipShape 与圆圈一起使用，但它不起作用。我按照教程“我的图像 1：SwiftUI 中的照片选择器和相机”进行操作

struct ProfileView: View {

@EnvironmentObject var appUser: User
@EnvironmentObject var appInfo: AppInformation

var body: some View {
    
    ZStack {
Rectangle()
            .frame(width: 400, height: 720)
    .cornerRadius(50)
    .foregroundColor(.gray)
    .overlay(
        
    HStack {
        
        if let image = appUser.profilBild {
    Image(uiImage: image)
            .resizable()
            .frame(width: 100, height: 100)
            .scaledToFill()
            .clipShape(RoundedRectangle(cornerRadius: 15))
            .overlay(Circle().stroke(Color.orange, lineWidth: 10))
            .onTapGesture {
                appInfo.source = .library
                appInfo.showPicker = true
            }
            .padding(20)
            .shadow(radius: 10)
            .overlay(
                ZStack{
                    Rectangle()
                        .frame(width: 20, height: 20)
                        .offset(x: 35, y: -35)
