Your app need to support a couple of things. If your app can have the background-running capability then you can do a couple of things.

To run periodically you will need a Timer (NSTimer). You will need a method which will execute the HTTP request.

Timer.scheduledTimer(timeInterval: 5, target: self, selector: #selector(callWebservice), userInfo: nil, repeats: true)

func callWebservice() {
  // Handle response 
}
