Xcode 15b3 Swift 5.9 C++ Interop with Network Extension

That’s a weird one. Please file a bug about it, and post your bug number, just for the record.

It seems that NEVPNStatusDidChangeNotification is being imported as a String rather than an element of NSNotification.Name. What’s interesting is that:

• The declaration in the header is this:

  NEVPN_EXPORT NSString * const NEVPNStatusDidChangeNotification …;
  

  where NEVPN_EXPORT expands to extern. Most of our notifications are declared like this:

  FOUNDATION_EXPORT NSNotificationName const NSSystemTimeZoneDidChangeNotification …;
  

  where the NSNotificationName is how Swift knows that this is member of the NSNotification.Name extensible enum.

• NEVPNStatusDidChangeNotification has no entry in the .apinotes file.

Given that, it’s not clear how NEVPNStatusDidChangeNotification getting mapped to a notification name in the normal case O-:

Regardless, a bug report is in order.

GAMECONTROLLER_EXTERN NSString *const GCKeyboardDidConnectNotification API_AVAILABLE(macos(11.0), ios(14.0), tvos(14.0));
GAMECONTROLLER_EXTERN NSString *const GCKeyboardDidDisconnectNotification API_AVAILABLE(macos(11.0), ios(14.0), tvos(14.0));

These have the same issue so should probably do an audit (this is from the RC of Xcode 15).

this is from the RC of Xcode 15

Indeed.

One of the nice things about Swift bugs is that you can check on their status in the Swift open source. In this case:

• PR 68217

• PR 68279

Sadly, the fix seems to have missed the Xcode 15.0 train.
