Summary:
Calling `CFHostStartInfoResolution` from `Swift` is impossible due to the method’s signature.

Steps to Reproduce:
Open a new `Playground` and paste the following code:
```
    let hostaddr = "google.com"
    let host:CFHost! = CFHostCreateWithName(kCFAllocatorDefault, hostaddr).takeRetainedValue()
    let error = UnsafeMutablePointer<CFStreamError>.alloc(1)
    if CFHostStartInfoResolution(host, CFHostInfoType.Addresses, error) {
      let hbr = UnsafeMutablePointer<Boolean>()
      addresses = CFHostGetAddressing(host, hbr)
    }
 
    host.release()
    error.dealloc(1)
```

Expected Results:
The code should compile and run.

Actual Results:
The compiler complains because the provided params doesn’t match the method’s signature even though they are the same.
