running a nested Alamofire request synchronously
0
I am trying to retrieve data from my node by making requests multiple times (to get the distance a car travels). However it seems that the executiono is not occuring in the right order. I believe this is due to the fact that the requests are not processed synchronously.
I have looked at other questions but it doesnt seem to fit my situation because of the nested requests.
var d1: Double!
var d2: Double!
var d3: Double!
var d4: Double!
var speed: Double!
var speed1: Double!
@objc func getSpeed() {
Alamofire.request("(Constants.appServer)/speed", method: .get).responseJSON { (response) in
if let result = response.result.value as! [String:Any]? {
if let response = result["data"] as! [String: Any]?
{
self.d1 = response["distance"] as? Double
print("First distance is (self.d1) KM")
//Delay for 5 secods
sleep(5)
//Make the call again.
Alamofire.request("(Constants.appServer)/speed", method: .get).responseJSON(completionHandler: { (response) in
if let result = response.result.value as! [String: Any]? {
if let response = result["data"] as! [String:Any]?
{
self.d2 = response["distance"] as? Double
print("The second distance is ((self.d2)!)")
let distance = self.d2 - self.d1
print("The total distance for the first part is (distance)")
self.speed = (distance / 5) * 1000
print("((self.speed)!) is the speed (m/s) for the first part")
}
}
})
}
}
}
sleep(30)
Alamofire.request("(Constants.appServer)/speed", method: .get).responseJSON { (response) in
if let result = response.result.value as! [String:Any]? {
if let response = result["data"] as! [String: Any]?
{
self.d3 = response["distance"] as? Double
print("The third distance is ((self.d3)!)")
//Delay for 5 secods
sleep(5)
//Make the call again.
Alamofire.request("(Constants.appServer)/speed", method: .get).responseJSON(completionHandler: { (response) in
if let result = response.result.value as! [String: Any]? {
if let response = result["data"] as! [String:Any]?
{
self.d4 = response["distance"] as? Double
print("The fourth distance is ((self.d4)!)")
let distance = self.d4 - self.d3
print("The total distance for the second part is (distance)")
self.speed = (distance / 5) * 1000
print("((self.speed)!) is the speed (m/s) for the second part")
}
}})
}
}
}
if speed1 == 0 && speed > 90 {
//Wait 5 minutes to see if the car moves
sleep(30)
if speed1 == 0 {
//Send SMS
Alamofire.request("(Constants.appServer)/message?long=longitude&lat=lat", method: .get).responseJSON { _ in}
}
}else {
print("There is no issue")
}
}
I am running the below function every 5 minutes or so in my appdelegate,

That's horrible. Please don't do that. There are APIs like Grand Central Dispatch which are able to maintain the order of asynchronous network requests. And please don't force unwrap an optional to an optional (as! [String: Any]?). If you want to conditional downcast the proper syntax isas? [String: Any]
