如何使用 swift 中的 json 数据检查 "switch" 语句

Question

我需要检查 for 循环中的多个 if 条件，所以我不能那样检查，所以如何使用下面代码中的 switch 语句

code: 这里如何将下面的代码变成 switch 语句。请指导我

let indexData = searchResult?.result?.search_result?[indexPath.row]


if let servDetls = indexData?.service_details{

for oneSerdet in servDetls{
    
    if self.keyword == oneSerdet.sub_category?.title{
        cell.serviceNameLbl.text = "\(oneSerdet.sub_category?.title?.capitalized ?? "ABC")"
  
    print("keyword: \(self.keyword ?? "") \n here the sub category tite: \(oneSerdet.sub_category?.title ?? "") \n user name: \(indexData?.first_name?.capitalized ?? "")")

    }
    else if self.keyword == oneSerdet.category?.title{
        cell.serviceNameLbl.text = "\(oneSerdet.category?.title?.capitalized ?? "")"
    }
    else{
        cell.serviceNameLbl.text = ""
    }
}
}

o/p: 这里来自用户名 Vikas, New 还需要显示 cell.serviceNameLbl.text 但不显示原因

 keyword: ecommerce web site 
 here the sub category tite: ecommerce web site 
 user name: Dips

 here the sub category tite: ecommerce web site 
 user name: James

你可以像这样使用 Switch 语句

switch self.keyword {
case oneSerdet.sub_category?.title:
    break
case oneSerdet.category?.title:
    break
default:
    break
}
