translate string with YandexAPI in for loop - ios

Question

I want to translate googleMap Api result for location address to Persian. i'm using YandexApi for translate address. separate address components with "،" and pass this array to for api. my problem is after every service call my userInterface updated. how can solve this problem.
for example when I pass this array to method:["road","avenue"]
address label text update after every translate response
first text for label = "جاده"
last text for label = "جاده ، خیابان"
there is my code:
func translateText(text:[String],closure:#escaping ((_ success:String?,_ error:Error?) -> Void)) {
var translateString: String = ""
var responseError: Error?
for item in text {
myGroup.enter()
let urlString = "https://translate.yandex.net/api/v1.5/tr.json/translate?key=trnsl.1.1.20171105T134956Z.795c7a0141d3061b.dc25bae76fa5740b2cdecb02396644dea58edd24&text=\(item)&lang=fa&format=plain&options=1"
if let allowString = Utilities.shareInstance.getQueryAllowedString(url: urlString) {
if let url = URL(string:allowString){
Alamofire.request(url).responseJSON { response in
guard let responseData = response.data else {
return
}
do {
let json = try JSONSerialization.jsonObject(with: responseData, options: [])
if let res = json as? [String:Any] {
if let code = res["code"] as? Int {
if code == 200 {
if let textArr = res["text"] as? [AnyObject] {
let flattArr = Utilities.shareInstance.flatStringMapArray(textArr)
if flattArr.count > 0 {
translateString += " ، " + flattArr[0]
}
}
}
}
}
}catch {
responseError = error
}
self.myGroup.leave()
closure(translateString, responseError)
}
}
}
}
}
private func translatingAddressArrayForChecking(address:[String]) {
var addressString = ""
let addressComponent = address
if addressComponent.count > 0 {
YandexTranslateAPI.shateInstance.translateText(text: addressComponent, closure:{ success,_ in
if let res = success {
addressString = res
OperationQueue.main.addOperation {
self.layoutActivity(start: false)
if self.searchState == .Origin && self.destinationButton.isHidden == false{
if let selectOrigin = self.originSelectedCity {
if let city = selectOrigin.city_title {
if addressString.contains(city) {
self.originAddressLabel.text = addressString
if let location = self.startCoordinate {
self.setOrigin(location: location)
}
}else {
self.CreateCustomTopField(text: "wrong city", color: Constants.ERROR_COLOR)
}
}
}
}else if self.searchState == .Destination || self.destinationButton.isHidden == true {
if let selectOrigin = self.destinationSelectedCity {
if let city = selectOrigin.city_title {
if addressString.contains(city) {
self.destinationAddressLabel.text = addressString
if let location = self.endCoordinate {
self.setDestination(location: location)
}
}else {
self.CreateCustomTopField(text: "wrong city", color: Constants.ERROR_COLOR)
}
}
}
}
}
}
})
}
addresses label text update multiple with array component.
