In Swift 2.1, how do you get the NSError that was thrown?

Question

I initialize AVCaptureDeviceInput. In Swift 2, instead of getting an NSError variable, you catch the error with a do-try-catch sandwich. However, I do not see how to get an NSError inside the catch part. The recommendation on the Apple Developer Forum does not indicate how you can access NSError.

Can someone enlighten me?

This worked for me:

var error: NSError? do { request.HTTPBody = try NSJSONSerialization.dataWithJSONObject(jsonString, options: []) } catch let error1 as NSError { error = error1 request.HTTPBody = nil } 

I hope it will be useful
