I have following code part of Philips Hue SDK in Objective C (imported with bridging header)

[self.bridgeSearch startSearchWithCompletionHandler:^(NSDictionary *bridgesFound) {

     // do something

}];

And I don't no, how to access this function in Swift.

I tried following (suggestion of Xcode 6)

    self.bridgeSearch?.startSearchWithCompletionHandler({ (bridgesFound:NSDictionary) -> Void in

        // do something

    })

But compiler brings following error:

'[NSObject : AnyObject]!' is not a subtype of 'NSDictionary'

Try changing the closure parameter into an optional: `bridgesFound: NSDictionary?` or `bridgesFound: NSDictionary!` – Antonio Nov 24 '14 at 21:34
Already tried, but not worked – mahega Nov 24 '14 at 21:42

Or `bridgesFound:[NSObject : AnyObject]!` – Martin R Nov 24 '14 at 21:44

This worked for me: self.bridgeSearch?.startSearchWithCompletionHandler({ bridgesFound in // do something }) – mahega Nov 24 '14 at 21:45
