[BUG] Library not loaded: @rpath/AzureCommunicationCommon.framework/AzureCommunicationCommon

Describe the bug

When installing the AzureCommunicationCalling pod into an iOS app using use_frameworks! :linkage => :static, the iOS app will crash with the following error:

To Reproduce

1. Create a new App in Xcode.
2. pod init, then add the following, then pod install. Open the generated Xcode workspace.

target 'MyTestApp' do
  use_frameworks! :linkage => :static

  pod 'AzureCommunicationCalling', '2.3.0'

end

3. Build will fail with Failed to build module 'AzureCommunicationCalling'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51)', while this compiler is 'Apple Swift version 5.8 (swiftlang-5.8.0.124.2 clang-1403.0.22.11.100)'). Please select a toolchain which matches the SDK.

• To resolve this, add a bridging header in Xcode with the following. The build will succeed.

#import <AzureCommunicationCalling/AzureCommunicationCalling.h>

4. Launch the app on an iPhone. It crashes with the aforementioned stack trace.

Expected behavior

:linkage => :static should work. Not all projects can use :linkage => :dynamic, and there's an existing issue with omitting the use_frameworks! line entirely ( https://github.com/Azure/azure-sdk-for-ios/issues/1517 ).

Setup

• macOS 13.3.1
• Xcode 14.3
• library version 2.3.0
