在Swift中将[NSObject，AnyObject]转换为[String，AnyObject]

Question

I have the following line which used to work in iOS 8 in Swift.

 let placemark = placemarks![0] as? CLPlacemark

 let destinationPlacemark = MKPlacemark(

     coordinate: placemark!.location!.coordinate, 
     addressDictionary: placemark?.addressDictionary

 )

but now it gives me the following exception:

Cannot convert value of type '[NSObject : AnyObject]?' to expected argument type '[String : AnyObject]?'

How can I do that?

Answer 1

您需要将类型[String : AnyObject]为[String : AnyObject]

placemark?.addressDictionary as? [String:AnyObject]
