Alamofire sending a request to an API 'NSInvalidArgumentException' - swift

Question

i am using this code to send an image and text to an api:
func uploadImageAndData(_ url:String,parameters1:Parameters,headers1:HTTPHeaders,images:[UIImage]){
Alamofire.upload(multipartFormData: { multipartFormData in
// import image to request
var i=0
for imageData in images {
// multipartFormData.append(self.resizeImage(image: uploadedProfileImage, targetSize: CGSize(width: 200, height: 200)
multipartFormData.append(imageData.pngData()!, withName: "profilePic", fileName: "profileimage"+".jpeg", mimeType: "image/jpeg")
i += 1
}
for (key, value) in parameters1 {
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
} ,to: url,method:.post,
headers:[:],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (Progress) in
print("showuing upload progress")
print("Upload Progress: \(Progress.fractionCompleted)")
//SwiftSpinner.show(progress: Progress.fractionCompleted*100, title: "تحميل")
})
upload.responseJSON { response in
print(response.response?.statusCode as Any)
if let data = response.result.value, let utf8Text = String(data: data as! Data, encoding: .utf8) {
print("New Func Data: \(utf8Text)")
}
switch response.response?.statusCode {
case 201 :
print("Success")
break
case 413 :
print("Post too large")
break
case 200 :
print("200")
break
case 400 :
print("400")
break
case 401 :
print("401")
break
case 302 :
print("302")
break
case 500 :
print("500")
break
default: break
}
}
return
case .failure(let encodingError): break
}
})
}
and i got these datas :
let address: Parameters = [
"location" : addressField.text!,
"locationLat" :pickedLocationLat,
"locationLong" :pickedLocationLong
]
let body: Parameters = [
"name": "Sample Name",
"email": "test#test.com",
"password": "test123",
"address": address
]
and i am accessing the function using this code
var head = [String:Any]()
head["Accept"]="application/json"
uploadImageAndData(BASE_URL", parameters1: body, headers1: head as! HTTPHeaders, images: [uploadedProfileImage])
this code is throwing an error like
Terminating app due to uncaught exception 'NSInvalidArgumentException'
reason: '-[_TtGCs26_SwiftDeferredNSDictionarySSP__$ dataUsingEncoding:]: unrecognized selector sent to instance 0x6000015bed00'
terminating with uncaught exception of type NSException
i dont know what is causing this problem the api requires a json body with a content-type of application/json
i tired removing all the content of the body parameter except for the name to try and send only the name and when i do that the image uploads successfully but it still gives me this error,so please help me figure out this problem.

Answer 1

You need to make values a string not double
let address: Parameters = [
"location" : addressField.text!,
"locationLat" :"\(pickedLocationLat)",
"locationLong" :"\(pickedLocationLong)"
]
