你好，

获得错误"；无法转换"ServiceModel"类型的值。Type"转换为所需的参数类型"ServiceModel"在ServicePagePreview(employeeGroup:ServiceModel(。我是否使用了错误的数据类型？

Answer 1

您在此处提供类型：ServicePageView(employeeGroup:ServiceModel(

我想你是想在ServiceModel((中给出一个实例这将是返回该类型的实例的init。

Answer 2

您需要将代码包装在一个"身体；作为一个视图，像这样：

struct ServicePageView: View {
@ObservedRealmObject var employeeGroup: ServiceModel
var body: some View {  // <--- here
...
}
}
