Swift 3 conversion error

[aleksanderkania]

Hello, I tried to convert HistogramDisplay to Swift 3 but I have a problem with this lines of code:

 let histogram = UnsafeMutablePointer<UnsafeMutablePointer<vImagePixelCount>>(mutating: rgba)       
 vImageHistogramCalculation_ARGB8888(&inBuffer, histogram, UInt32(kvImageNoFlags))

the vImageHistogramCalculation_ARGB8888 method is still same as in Swift 2.3 but I can't properly initialized an optional UnsafeMutablePointer<UnsafeMutablePointer<vImagePixelCount>> method. Some ideas? :)

I received the error:

: Cannot invoke initializer for type 'UnsafeMutablePointer<UnsafeMutablePointer<vImagePixelCount>?>' with an argument list of type '(mutating: [UnsafeMutablePointer<vImagePixelCount>])'
