I know have many the same question but still cannot find the way to fix my error. Please see the image for more detail. I used Xcode 7 and swift 2.0

Edit: fcking the warning of Swift. finnaly (change?[NSKeyValueChangeNewKey]?.boolValue)! fixed the error

change is an optional. Either unwrap the optional

let isCaptureStillImage = change![NSKeyValueChangeNewKey]!.boolValue

or use optional bindings

if let changeNewKey = change?[NSKeyValueChangeNewKey] {
  let isCaptureStillImage = changeNewKey.boolValue

...
