Thank you so much. That's exactly what I needed!

Re: [swift-users] How to create an uninitialized pointer in Swift 3

[Martin R via swift-users]

In Swift 3, COpaquePointer was renamed to OpaquePointer, and nullable pointers 
are represented by optionals:

  SE-0055 – Make unsafe pointer nullability explicit using Optional
  
https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md

So the following should work in Swift 3:

  var cublasHandle: OpaquePointer?
  let status = cublasCreate_v2(&cublasHandle)
