ios - How do I get a plist as a Dictionary in Swift?

Question

I am playing around with Apple's new Swift programming language and have some problems...

Currently I'm trying to read a plist file, in Objective-C I would do the following to get the content as a NSDictionary:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Config" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:filePath];

How do I get a plist as a Dictionary in Swift?

I assume I can get the path to the plist with:

let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist")

When this works (If it's correct?): How do I get the content as a Dictionary?

Also a more general question:

Is it OK to use the default NS* classes? I think so...or am I missing something? As far as I know the default framework NS* classes are still valid and alright to use?

You can still use NSDictionaries in Swift:

For Swift 4

 var nsDictionary: NSDictionary?
 if let path = Bundle.main.path(forResource: "Config", ofType: "plist") {
    nsDictionary = NSDictionary(contentsOfFile: path)
 }

For Swift 3+

if let path = Bundle.main.path(forResource: "Config", ofType: "plist"),
   let myDict = NSDictionary(contentsOfFile: path){
    // Use your myDict here
}

And older versions of Swift

var myDict: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist") {
    myDict = NSDictionary(contentsOfFile: path)
}
if let dict = myDict {
    // Use your dict here
}

The NSClasses are still available and perfectly fine to use in Swift. I think they'll probably want to shift focus to swift soon, but currently the swift APIs don't have all the functionality of the core NSClasses.
