Swift 3 - Trying to cast a dictionary to CFDictionary

When I'm trying to create an array as a CFDictionary, I'm getting an error (shown bellow).

This is the code:

let attrs = [kCVPixelBufferCGImageCompatibilityKey:kCFBooleanTrue,  kCVPixelBufferCGBitmapContextCompatibilityKey:kCFBooleanTrue] as CFDictionary

But the weird thing is that I'm using the same line of code in another project, without receiving any errors. What does the error mean?

Error: Contextual type 'CFDictionary' cannot be used with dictionary literal

             kCVPixelBufferCGBitmapContextCompatibilityKey as String:kCFBooleanTrue] as
        CFDictionary
