For-In循環Swift 3中的多個條件

Question

如何使用for循環並添加我的四個字符串值的數組。請檢查下面的代碼：

let facilityID = FacilityID.map { "\($0)"}.joined(separator: ",") 
let charges_per_km = ServiceChargesPerKilomiter.map { "\($0)"}.joined(separator: ",") 
let charges_per_Minute = ServicChargesPerMinute.map { "\($0)"}.joined(separator: ",") 

var request = URLRequest(url: URL(string: NetworkRequest.hostpath+"save_service_request.php")!) 
request.httpMethod = "POST" 

var data: [[String: Any]] = [] 

for i in 0..<facilityName.count { 
    let dataArray = 
     [ 
      "facility_id": (facilityID), 
      "facility_name": facilityName[i], 
      "charges_per_km": (charges_per_km), 
      "charges_per_minute": (charges_per_Minute), 
     ] 

    data.append(dataArray) 
} 

如何添加facilityID，Charges_per_km和charges_per_Minute我for循環內？我將在for in循環中添加facility_name。

任何人都可以幫助我嗎？

假設你正在處理四個單獨的數組並且想要單個字典數組，你不需要（也不需要）這些map語句。你可以做到以下幾點：

var data = [[String: Any]]() 

for i in 0 ..< facilityName.count { 
    data.append([ 
     "facility_id": FacilityID[i], 
     "facility_name": facilityName[i], 
     "charges_per_km": ServiceChargesPerKilomiter[i], 
     "charges_per_minute": ServicChargesPerMinute[i] 
    ]) 
} 

或者，如果你需要他們爲字符串：

var data = [[String: String]]() 

for i in 0 ..< facilityName.count { 
    data.append([ 
     "facility_id": "\(FacilityID[i])", 
     "facility_name": facilityName[i], 
     "charges_per_km": "\(ServiceChargesPerKilomiter[i])", 
     "charges_per_minute": "\(ServicChargesPerMinute[i])" 
    ]) 
}
