.sdk(v = nil) ⇒ Object

If a specific SDK is requested:

  1. The requested SDK is returned, if it’s installed.
  2. If the requested SDK is not installed, the newest SDK (if any SDKs are available) is returned.
  3. If no SDKs are available, nil is returned.

If no specific SDK is requested:

  1. For Xcode >= 7, the latest SDK is returned even if the latest SDK is named after a newer OS version than the running OS. The MACOSX_DEPLOYMENT_TARGET must be set to the OS for which you’re actually building (usually the running OS version).

  2. For Xcode < 7, proceed as if the SDK for the running OS version had specifically been requested according to the rules above.
