Public protocols rely on AVFoundation type deprecated in iOS 17.0

[patrickhartling]

Description

If a consumer of the framework has their deployment target set to iOS 17.0 or newer, the Swift compiler will report deprecation warnings from TVICameraSourceOrientationTracker.h. These are associated with AVCaptureVideoOrientation being deprecated in iOS 17.0 and newer.

The warnings look like the following when using TwilioVideo with Swift Package Manager:

/.../Library/Developer/Xcode/DerivedData/.../Build/Products/Debug-iphoneos/TwilioVideo.framework/Headers/TVICameraSourceOrientationTracker.h:28:38 'AVCaptureVideoOrientation' is deprecated: first deprecated in iOS 17.0 - Use AVCaptureDeviceRotationCoordinator instead

'AVCaptureVideoOrientation' has been explicitly marked deprecated here
In file included from <module-includes>:1:
In file included from /.../Library/Developer/Xcode/DerivedData/.../Build/Products/Debug-iphoneos/TwilioVideo.framework/Headers/TwilioVideo.h:22:

/.../Library/Developer/Xcode/DerivedData/.../Build/Products/Debug-iphoneos/TwilioVideo.framework/Headers/TVICameraSourceOrientationTracker.h:51:41 'AVCaptureVideoOrientation' is deprecated: first deprecated in iOS 17.0 - Use AVCaptureDeviceRotationCoordinator instead

'AVCaptureVideoOrientation' has been explicitly marked deprecated here

/.../Library/Developer/Xcode/DerivedData/.../Build/Products/Debug-iphoneos/TwilioVideo.framework/Headers/TVICameraSourceOrientationTracker.h:71:41 'AVCaptureVideoOrientation' is deprecated: first deprecated in iOS 17.0 - Use AVCaptureDeviceRotationCoordinator instead

'AVCaptureVideoOrientation' has been explicitly marked deprecated here

More specifically, the warnings are associated with the following public protocols:

• TVICameraSourceOrientationDelegate
• TVICameraSourceOrientationTracker
• TVIUserInterfaceTracker

Steps to Reproduce

1. Open the Xcode project (attached below as TwilioTest.zip) in Xcode 15.
2. Build the project.

Code

TwilioTest.zip

Expected Behavior

I would not expect the Swift compiler to emit deprecation warning from a dependency, particularly when the dependency has a deployment target set wherein the deprecation warning does not apply. However, that is not how things work today with Swift.

Actual Behavior

The warnings shown above are reported and cannot be addressed by the user of the framework. Any implementation of one of the protocols involved will also result in deprecation warnings being reported.

Reproduces How Often

Always.

Same issue here. Seems to be related to enabling Explicitly built Modules build setting.
