如何从api响应获取数据以快速显示在标签上

Question

我正在尝试获取 API 数据以在标签中显示，我在模型中成功获取 api 响应，如何在视图控制器中获取响应值以显示在标签上。这是在 codeViewController 类中获取 json 响应的方法

private textCode:CodeModel
private func load() {
    codeProvider.load(target: .myCode, withActivity: true) {[weak self] result in
        switch result {
        case .success(let response):
            print(response,"response here")
            self?.textCode = response
            self?.output.perform(action: .didLoad)
            case .failure(let error):
            print(error)
                
        }
    }
}
extension CodeModel: codeViewControllerOutput {
var displayable: DisplayableCode {
    DisplayableCode(user: textCode)
 }

，我试图调用可显示的

 private func fillFields() {
    let d = model.displayable
    codeLabl.text = d.someTextcode
}

致命错误：隐式解包时意外发现 nil 可选值
