An example from
http://www.sitepoint.com/using-legacy-c-apis-swift/:
Calling the C function "void takesAnObject(void *theObject);"
from Swift:
var test = 42
withUnsafePointer(&test, { (ptr: UnsafePointer<Int>) -> Void in
var voidPtr: UnsafePointer<Void> = unsafeBitCast(ptr,
UnsafePointer<Void>.self)
takesAnObject(voidPtr)
})
Maybe it can be done better, but I think it is rather obvious
that if interfacing looks like that, one doesn't loose much from
implementing the app using Objective-C++ and Swift without
bridging much between C++ and Swift.
