Enabling C++ Interoperability breaks Swift code

[wAuner]

Description

When I enable C++ interoperability on my framework target, the Swift code (see below) in my framework breaks and no longer compiles. Setting the interoperability back to C lets me compile the code again.

Reproduction

1. create an Xcode project (tested with 15.3 and Sonoma 14.4) with a framework target
2. add a Swift source file with this example code

import Foundation

public func readPlist() {
   let plistData = try! Data(contentsOf: URL(string:"/tmp/some.plist")!)
   let plist = try! PropertyListSerialization.propertyList(from: plistData, options: .mutableContainersAndLeaves, format: nil) as? [String: Any]
}

3. this compiles without errors, but when I set C++ interoperability to C++, it no longer comiles and gives the following warning:
   

Expected behavior

Successful compilation should not depend on interoperability setting.

Environment

swift-driver version: 1.90.11.1 Apple Swift version 5.10 (swiftlang-5.10.0.13 clang-1500.3.9.4)
Target: arm64-apple-macosx14.0
