calloc in Swift

Question

How do I transform the following ObjectiveC statements into SWIFT:

UInt32 *pixels;
pixels = (UInt32 *) calloc(height * width, sizeof(UInt32));

Answer 1

For Swift-3 : UnsafeMutablePointer is replace by UnsafeMutableRawPointer

 var pixels = UnsafeMutableRawPointer( calloc(height * width, MemoryLayout.size) )
