Enabling C++ interop breaks existing swift code

Development C++ interoperability
1

I'm running into an issue when enabling C++ interop. I've check this in both an app enabling C++ interop as well as a swift package.

Code that was previously compilable I'm noticing is getting a number of errors. Below are a few examples.

Foundation
Issue 1 - CGSize

var viewportSize: CGSize = CGSize()

This compiles without issue with interop disabled but gives the following message with interop enabled.
Missing argument for parameter 'from' in call

Issue 2 - Notification Center Notification.Name

NotificationCenter.default.removeObserver(self, name: .AVCaptureDeviceWasDisconnected, object: nil)
NotificationCenter.default.removeObserver(self, name: .AVCaptureDeviceWasConnected, object: nil)

It seems that .AVCaptureDeviceWasDisconnected and .AVCaptureDeviceWasDisconnected are no longer available when interop is enabled.

I've seen a few more. Is this a known issue, or are some of these implementations changed when I enable interop?

Thank you

Did you figure out a solution to the issue 2?

Sorry that you didn't get a response. It's certainly always possible for changing language modes to cause problems, but these seem unexpected, and they're definitely worth reporting as bugs with the Apple feedback assistant.

I'm facing the same issues. Is there any progress on this?

In my case, my project's using C / Objective-C. Due to a new SDK integration, I need to switch to using C++ / Objective-C++, then these issues occur.

I also just ran into a case that breaks Swift code. I've posted a description in a github issue.
