Google APIを使用してルートデータを取得しようとしていますが、クラッシュしています。それは私がスウィフトGoogle Directions API JSON - EXC_BAD_INSTRUCTION（コード= EXC_I386_INVOP、サブコード= 0x0）
if let dictionary: Dictionary<NSObject, AnyObject> = try NSJSONSerialization.JSONObjectWithData(directionsData!, options: .MutableContainers) as? Dictionary<NSObject, AnyObject> {
self.overviewPolyline = self.selectedRoute["overview_polyline"] as! Dictionary<NSObject, AnyObject>
との "EXC_BAD_INSTRUCTION（コード= EXC_I386_INVOP、サブコード= 0x0のを）" と言う
let baseURLDirections = "https://maps.googleapis.com/maps/api/directions/json?"
var selectedRoute: Dictionary<NSObject, AnyObject>!
var overviewPolyline: Dictionary<NSObject, AnyObject>!
var originCoordinate: CLLocationCoordinate2D!
var destinationCoordinate: CLLocationCoordinate2D!
var originAddress: String!
var destinationAddress: String!
func getDirections(origin: String, destination: String, waypoints: Array<String>!, travelMode: AnyObject!, completionHandler: ((status: String, success: Bool) -> Void)) {
var directionsURLString = baseURLDirections + "origin=" + origin + "&destination=" + destination
directionsURLString = directionsURLString.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())!
let directionsURL = NSURL(string: directionsURLString)
let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: directionsURL!)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(urlRequest) {
(data, response, error) -> Void in
do {
let directionsData = NSData(contentsOfURL: directionsURL!)
if let dictionary: Dictionary<NSObject, AnyObject> = try NSJSONSerialization.JSONObjectWithData(directionsData!, options: .MutableContainers) as? Dictionary<NSObject, AnyObject> {
let status = dictionary["status"] as! String
if status == "OK" {
self.selectedRoute = (dictionary["routes"] as! Array<Dictionary<NSObject, AnyObject>>)[0]
self.overviewPolyline = self.selectedRoute["overview_polyline"] as! Dictionary<NSObject, AnyObject>
let legs = self.selectedRoute["legs"] as! Array<Dictionary<NSObject, AnyObject>>
let startLocationDictionary = legs[0]["start_location"] as! Dictionary<NSObject, AnyObject>
self.originCoordinate = CLLocationCoordinate2DMake(startLocationDictionary["lat"] as! Double, startLocationDictionary["lng"] as! Double)
let endLocationDictionary = legs[legs.count - 1]["end_location"]as! Dictionary<NSObject, AnyObject>
self.destinationCoordinate = CLLocationCoordinate2DMake(endLocationDictionary["lat"] as! Double, endLocationDictionary["lng"] as! Double)
self.originAddress = legs[0]["start_address"]as! String
self.destinationAddress = legs[legs.count - 1]["end_address"]as! String
self.calculateTotalDistanceAndDuration()
completionHandler(status: status, success: true)
}

completionHandler(status: status, success: false)

task.resume()

：ここに私のコードです
私はEXC_BAD_INSTRUCTION（コード= EXC_I386_INVOP、サブコード= 0x0）を取得しています。 これをどのように解決すればよいですか？
はそのoptionalsを確認してくださいあなたは力のアンラッピングは実際にはゼロではありません。 –
