Swift 2 で Xcode 6 を Xcode 7 ベータ版に更新しました。このエラーが発生し、修正方法がわかりません。助けてください。ありがとう。これは私のコードです:

 func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location = locations.last as! CLLocation

    let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.map.setRegion(region, animated: true)
}

そして、私はこのエラーが発生します:

Objective-C method 'locationManager:didUpdateLocations:' provided by method 'locationManager(_:didUpdateLocations:)' conflicts with optional requirement method 'locationManager(_:didUpdateLocations:)' in protocol 'CLLocationManagerDelegate'

あなたと同じ問題がありました、変更してください

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject])

に

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])

プロジェクトをクリックします - Build Phases->Link Binary With Libraries に移動し、CoreLocation.framework を追加します

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

let locationManager = CLLocationManager()
var LatitudeGPS = NSString()
var LongitudeGPS = NSString()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    updateLocation()

func updateLocation() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    //self.locationManager.distanceFilter = 10
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {

    locationManager.stopUpdatingLocation() // Stop Location Manager - keep here to run just once

    LatitudeGPS = String(format: "%.6f", manager.location!.coordinate.latitude)
    LongitudeGPS = String(format: "%.6f", manager.location!.coordinate.longitude)
    print("Latitude - \(LatitudeGPS)")

}

これは、xcode 7 で動作する私のコードです。また、コードをクリーンアップする必要がありました (Product->Clean)

@objcクラスまたはメソッドを属性でマークする必要があります。したがって、次のいずれかです。

@objc class MyManagerDelegate: NSObject, CLLocationManagerDelegate {

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
        ...
    }

}

または：

class MyManagerDelegate: CLLocationManagerDelegate {

    @objc func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
        ...
    }

}

-1 
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations.last as! CLLocation!
    manager.stopUpdatingLocation()
    let region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude), span: MKCoordinateSpan(latitudeDelta: 0.001, longitudeDelta: 0.001))
    mapView.setRegion(region, animated: true)
