Here is my problem I can print in console double value (aka the distance) but I can't take a double and add the distance in a table view for exemple.
if previousLocation == nil {
previousLocation = locations.first
} else {
guard let latest = locations.first else { return }
let distanceInMeters = previousLocation?.distance(from: latest) ?? 0
print("Distance in meters: \(distanceInMeters)")
guard var unwrappedPaceNumber = paceNumber.first else { return }
let total = unwrappedPaceNumber += "\(distanceInMeters)"
paceNumber[0] = "\(total)"
tableView.reloadData()
previousLocation = latest
}
I finally ended up like that
If this can help
if previousLocation == nil {
previousLocation = locations.first
} else {
guard let latest = locations.first else { return }
let distanceInMeters = previousLocation?.distance(from: latest) ?? 0
var distanceRounded = distanceInMeters.rounded()
print("Distance in meters: \(distanceRounded)")
let unwrappedPaceNumber = paceNumber[0]
distanceRounded += Double(unwrappedPaceNumber)!
paceNumber[0] = "\(distanceRounded)"
print(paceNumber[0])
tableView.reloadData()
previousLocation = latest
}

I have task model in database (using realm), which consists of id, title, distance, longitude, latitude, customerAddress. I'm trying update my distance to task. I'm new to swift so I do not understand how should I fix geoCoder.geocodeAddressString closure, so that all tasks would update with their distance. (when task does not have latitude and longitude I check if task has customeradress by using geocodeAddressString
func updateTasksDistance() {
// get tasks for db
guard let tasks = Task.getAllUserTasks() else { return }
// last tracked location
guard let lastLocation = lastLocation else { return }
let myLocation = CLLocation(latitude: lastLocation.coordinate.latitude, longitude: lastLocation.coordinate.longitude)
var distance = 0
tasks.forEach({ (task) in
// check if task has longitude and latitude
if let lat = Double(task.latitude), let long = Double(task.longitude), lat != 0 && long != 0 {
let taskLocation = CLLocation(latitude: lat, longitude: long)
distance = Int(taskLocation.distance(from: myLocation))
} else if !task.customerAddress.isEmpty { // check if task has address
geoCoder.geocodeAddressString(task.customerAddress) { placemarks, _ in
if let placemark = placemarks?.first, let location = placemark.location {
self.taskLocationCoordinate = CLLocation(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude )
}
}
}
// check if we have closure location??
if let taskLocation = taskLocationCoordinate {
distance = Int(CLLocation(latitude: taskLocation.coordinate.latitude, longitude: taskLocation.coordinate.longitude).distance(from: myLocation))
taskLocationCoordinate = nil
}
// update my distance to task
updateTaskDistanceDb(task: task, with: distance)
// reset distance
distance = 0
})
}
// update task distance in db
fileprivate func updateTaskDistanceDb(task: Task, with distance: Int) {
let realm = try? Realm()
if let realm = realm {
do {
try realm.write {
task.distance = distance
}
} catch {
print("error")
}
}
}
Current result: distance gets updated correctly where closure is not called, but when closure is getting called then I get out of order results
expected result: all tasks distance relative to mine updated correctly
Fixed this issue by using this code:
fileprivate func geoCode(addresses: [String], results: [CLPlacemark] = [], completion: #escaping ([CLPlacemark]) -> Void ) {
guard let address = addresses.first else {
completion(results)
return
}
let geoCoder = CLGeocoder()
geoCoder.geocodeAddressString(address) { placemarks, _ in
var updatedResults = results
if let placemark = placemarks?.first {
updatedResults.append(placemark)
}
let remainingAddresses = Array(addresses[1..<addresses.count])
self.geoCode(addresses: remainingAddresses, results: updatedResults, completion: completion)
}
}
func updateTasksDistance() {
// get tasks for db
guard let tasks = Task.getAllUserTasks() else { return }
// last tracked location
guard let lastLocation = lastLocation else { return }
let myLocation = CLLocation(latitude: lastLocation.coordinate.latitude, longitude: lastLocation.coordinate.longitude)
let dispatchGroup = DispatchGroup()
for task in tasks where !task.customerAddress.isEmpty {
let addresses = [task.customerAddress]
dispatchGroup.enter()
geoCode(addresses: addresses) { results in
guard let customerAdress = results.first else { return }
guard let customerLocatin = customerAdress.location else { return }
let taskLocation = CLLocation(latitude: customerLocatin.coordinate.latitude,
longitude: customerLocatin.coordinate.longitude )
// do additional sutff
dispatchGroup.leave()
}
}
dispatchGroup.notify(queue: DispatchQueue.main, execute: {
// got all the address
}
})
}
Recursive geocode function helped to calculate all coordinates and dispatchGroup.notify is for waiting till all addresses are geocoded.
i have 3 annotation and i draw polyline between first and second annotation but i need the therd one move over that polyline but it's always move in street polyline to the destnation
-my code
func moveDelivery(_ destinationCoordinate : CLLocationCoordinate2D{
self.deliveryAnnotation.coordinate = CLLocationCoordinate2DMake(29.959640, 31.270421)
let sourcePlaceMark = MKPlacemark(coordinate: self.userAnnotation.coordinate)
//sourcePlaceMark.title
let destPlaceMkark = MKPlacemark(coordinate: self.deliveryAnnotation.coordinate)
let sourceItem = MKMapItem(placemark: sourcePlaceMark)
let destItem = MKMapItem(placemark: destPlaceMkark)
let directionRequest = MKDirections.Request()
directionRequest.source = sourceItem
directionRequest.destination = destItem
directionRequest.transportType = .any
let direction = MKDirections(request: directionRequest)
direction.calculate(completionHandler: {
response, error in
guard let response = response else {
if let error = error {
print(error.localizedDescription)
} else {
self.deliveryAnnotation.courseDegrees = self.getHeadingForDirectionFromCoordinate(self.kitchenAnnotation.coordinate, toLoc: self.userAnnotation.coordinate)
self.view.transform = CGAffineTransform(rotationAngle:CGFloat(self.deliveryAnnotation.courseDegrees))
}
return
}
guard let primaryRoute = response.routes.first else { return }
let route = response.routes[0]
self.mapView.addOverlay(route.polyline, level: .aboveRoads)
let rekt = route.polyline.boundingMapRect
self.mapView.setRegion(MKCoordinateRegion(rekt), animated: true)
})
//
UIView.animate(withDuration: Double(60), animations: {
self.deliveryAnnotation.coordinate = destinationCoordinate
}, completion: { success in
if success {
}
})
}
Your third annotation isn't following the route because you're animating it moving in a straight line between the first and second line. Try getting the coordinates from the MKRoute's polyline and animate between each one (According to apple's docs MKRoutes are made up of coordinates, but you might be able to use points as well)
If you'd like it to animate over the span of 60 seconds:
func moveDelivery(_ destinationCoordinate: CLLocationCoordinate2D) {
// I don't know why you have the delivery annotation start here, is this for testing?
deliveryAnnotation.coordinate = CLLocationCoordinate2DMake(29.959640, 31.270421)
let sourcePlaceMark = MKPlacemark(coordinate: destinationCoordinate)
let destPlaceMkark = MKPlacemark(coordinate: userAnnotation.coordinate)
let directionRequest = MKDirections.Request()
directionRequest.source = MKMapItem(placemark: sourcePlaceMark)
directionRequest.destination = MKMapItem(placemark: destPlaceMkark)
directionRequest.transportType = .any
let direction = MKDirections(request: directionRequest)
direction.calculate(completionHandler: {
response, error in
guard let response = response else {
print("MKRequest gave no response")
if let error = error {
print(error.localizedDescription)
} else {
self.deliveryAnnotation.courseDegrees = self.getHeadingForDirectionFromCoordinate(self.kitchenAnnotation.coordinate, toLoc: self.userAnnotation.coordinate)
self.view.transform = CGAffineTransform(rotationAngle:CGFloat(self.deliveryAnnotation.courseDegrees))
}
return
}
guard let primaryRoute = response.routes.first else {
print("response has no routes")
return
}
self.mapView.addOverlay(primaryRoute.polyline, level: .aboveRoads)
let rekt = primaryRoute.polyline.boundingMapRect
self.mapView.setRegion(MKCoordinateRegion(rekt), animated: true)
let coordinateArray = primaryRoute.polyline.coordinates
assert(coordinateArray.count > 0, "coordinate array is empty")
self.routeCoordinates = coordinateArray
// initiate recursive animations
self.coordinateIndex = 0
})
}
var routeCoordinates = [CLLocationCoordinate2D]()
var avgAnimationTime: Double {
return 60 / Double(routeCoordinates.count)
}
var coordinateIndex: Int! {
didSet {
guard coordinateIndex != routeCoordinates.count else {
print("animated through all coordinates, stopping function")
return
}
animateToNextCoordinate()
}
}
func animateToNextCoordinate() {
let coordinate = routeCoordinates[coordinateIndex]
UIView.animate(withDuration: avgAnimationTime, animations: {
self.deliveryAnnotation.coordinate = coordinate
}, completion: { _ in
self.coordinateIndex += 1
print("moved between coordinates")
})
}
EDIT
make sure to include this extension, otherwise you won't be able to get the coordinates of the MKRoute (source: https://gist.github.com/freak4pc/98c813d8adb8feb8aee3a11d2da1373f)
public extension MKMultiPoint {
var coordinates: [CLLocationCoordinate2D] {
var coords = [CLLocationCoordinate2D](repeating: kCLLocationCoordinate2DInvalid,

return coords
}
}
EDIT #2
See above, edited original answer to animate through each coordinate after the previous finishes animating. Really rough but it should work.
EDIT #3
Added your code to get the destination variable as well as some assert and debug printing calls. If things aren't working this time, please tell me which debug messages you get.

I have a global variable "filterError" that is initially set to false before a switch statement. When the switch statement occurs, it will go through a dictionary, and for each key it will do a unique logic check on the value. If that value does not match certain criteria then the Boolean variable filterError will be set to true.
When the switch statement is complete, if filterErrror is false then the an action will occur like so:
//...switch statement...
if (filterErrror == false) {
//do something.....
}
The issue I am having is with the geocoder function which is a case in the switch statement. If the switch variable key = "area" then the below is executed:
var geocoder = CLGeocoder()
geocoder.geocodeAddressString(address) { (placemarks, error) in
guard let placemarks = placemarks,let location = placemarks.first?.location
else { print("Error in finding location") return }
let distanceInMeters = location.distance(from: coordinateSelf)
print("The distance between property and user in miles is: \(distanceInMeters/1609)")
distanceInMiles = distanceInMeters/1609
var radius = Double()
if searchRadius == "this area only" {
radius = 0.49999999999
} else {
radius = Double(Int(searchRadius)!)
}
if (radius < distanceInMiles) {
filterError = true
}
}
However, the filterError is still false after the switch statement has completed because the boolean value is not being changed. How do you set filterError to true from inside the geocoder?
This is the full code:
for filter in self.activeFilters {
switch filter.key {
case "listingType":
if(filter.value[0] != propertiesFirestore[i]["listingType"]![0]){
filterError = true
}
case "minBedsBound":

}
}

if(filter.value[0] != "No max. beds") {

filterError = true
}

}
}

}

Below I have a list of cities and I compare a user's current location to the cities and use the (min) function
let closestCity = min(theDistanceInMetersFromBusselton,theDistanceInMetersFromBunbury,theDistanceInMetersFromJoondalup,theDistanceInMetersFromArmadale)
to return the closest city, though now I would like to return the second and third closest city.
I haven't been able to get this to work as yet though I'm thinking something along the lines of:
citiesArray - closestCity = SecondClosestCitiesArray
then do a secondClosestCity = min(SecondClosestCitiesArray) to get the second closest city.
Then repeat this to find the third closest?
Any ideas?

You can add these value into an array and while adding it, make sure that they are getting added to sorting order. The array at any given point will give you closest city on the first index and second closest city on the second index.
Here is an example :
extension Array where Element == Double {
mutating func appendSorted(_ element: Double) {
if self.count == 0 {
self.append(element)
return
}
for i in 0..<self.count {
if element < self[i] {
self.insert(element, at: i)
return
}
}
self.append(element)
}
}
I want to have a the distance from my Currentlocation to a annotation that's in the FireData Base. I tried to make it word but i can't ;(. I would like to have the distance between the two locations in a var. I hope you guys can help me.
func reload(){
//get data

print("Error while build route")
} else {
let route = response?.routes.last
let distance = route?.distance
print(distance)
}
})
}
}
}
}
}
})
}
Here is my Structure:
Try to use this code. Don't forget to enable your current location on map
let directionRequest = MKDirectionsRequest()
directionRequest.source = MKMapItem.forCurrentLocation()
directionRequest.destination = MKMapItem(placemark: MKPlacemark.init(coordinate: CLLocationCoordinate2DMake(YOURPOINTLATITUDE, YOURPOINTLONGITUDE)))
directionRequest.transportType = .walking
let direction = MKDirections(request: directionRequest)
direction.calculate(completionHandler: { (response, error) in
if error != nil {
print("Error while build route")
} else {
let route = response?.routes.last
let distance = route?.distance
I have used similar function, NOTE this was my function therefore it has rider and driver.. however you can change it to use annotation and location from firebase.
if let rideRequestDictionary = snapshot.value as? [String:AnyObject] {
// Getting the rider location and email
if let email = rideRequestDictionary["email"] as? String {
if let lat = rideRequestDictionary["lat"] as? Double{
if let lon = rideRequestDictionary["lon"] as? Double{
// Getting the Driver location and email
let driverCLLocation = CLLocation(latitude: driverLocation.latitude, longitude: driverLocation.longitude)
let riderCLLocation = CLLocation(latitude: lat, longitude: lon)
// getting the distance between the two people
let distance = driverCLLocation.distance(from: riderCLLocation) / 1000
// rounding the distances
let roundedDistance = round(distance * 100) / 100
// putting the rounded distance and email in label
cell.textLabel?.text = "\(email) - \(roundedDistance)km away"
}
}
}
