SwiftUI - 在 JSON 响应中显示嵌套数组 - 尝试将表达式分解为不同的子表达式

如何解决SwiftUI - 在 JSON 响应中显示嵌套数组 - 尝试将表达式分解为不同的子表达式

我有以下 JSON 响应。

{
   "results":[
      {
         "TrimName":"Truck","VIN":"GTJ3E18JF164623","Price": 47600,"odometer": 35511,"odometerType": "Miles","OptionCodeSpecs":{
            "C_Specs":{
               "code":"C_Specs","name":"Specs","options":[
                  {
                     "code":"Specs_acceleration","name":"5.2 sec","long_name":"5.2 seconds","description":"0-60 mph"
                  },{
                     "code":"Specs_TOP_SPEED","name":"140 mph","long_name":"140 miles per hour","description":"Top Speed"
                  },{
                     "code":"Specs_RANGE","name":"264 mi","long_name":"264 miles","description":"range (EPA)"
                  }
               ]
            }
         }
      }
   ],"total_matches_found":"53"
}

我使用 app.quicktype.io 构建了 Struct。

// MARK: - InventoryModel
struct InventoryModel: Codable {
    let results: [Result]
    let totalMatchesFound: String

    enum CodingKeys: String,CodingKey {
        case results
        case totalMatchesFound = "total_matches_found"
    }
}

// MARK: - Result
struct Result: Codable {
    let trimName,vin: String
    let price,odometer: Int
    let odometerType: String
    let optionCodeSpecs: OptionCodeSpecs

    enum CodingKeys: String,CodingKey {
        case trimName = "TrimName"
        case vin = "VIN"
        case price = "Price"
        case odometer = "odometer"
        case odometerType = "odometerType"
        case optionCodeSpecs = "OptionCodeSpecs"
    }
}

// MARK: - OptionCodeSpecs
struct OptionCodeSpecs: Codable {
    let cSpecs: CSpecs

    enum CodingKeys: String,CodingKey {
        case cSpecs = "C_Specs"
    }
}

// MARK: - CSpecs
struct CSpecs: Codable {
    let code,name: String
    let options: [Option]
}

// MARK: - Option
struct Option: Codable {
    let code,name,longName,optionDescription: String

    enum CodingKeys: String,CodingKey {
        case code,name
        case longName = "long_name"
        case optionDescription = "description"
    }
}

我能够成功检索到 JSON 响应。

@Published var getInventoryQuery: InventoryModel = InventoryModel(results: [],totalMatchesFound: "")

在我的 ContentView 中，我能够在 Results 对象中显示数据，但我无法访问 OptionCodeSpecs 对象中的 options 数组而不会出现以下错误：

编译器无法在合理的时间内对该表达式进行类型检查；尝试将表达式分解为不同的子表达式

Xcode 版本 12.5.1 (12E507)

@Observedobject var inv = GetInventory()

以下效果很好。为清楚起见，代码跳闸了。

ScrollView(.horizontal,showsIndicators: false){
                
                HStack(spacing: 10){
                    
                    ForEach(inv.getInventoryQuery.results,id: \.trimName) { inventory in
                        
                        vstack(alignment: .leading) {
                            
                            vstack(alignment: .center) {
                                
                                Text(inventory.trimName)

但是，当我尝试访问选项数组时，出现以下错误：

The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

HStack(alignment: .center){
                                    
                                    ForEach(inv.getInventoryQuery.results[inventory].optionCodeSpecs.cSpecs.options) { options in
                                    Text(options.longName)
                                        .font(.headline)
                                        .fontWeight(.light)
                                    
                                    Image(systemName: "battery.100")
                                        .renderingMode(.original)
                                    }
                                }
