Xcode – Swift linker error: Undefined symbol for surely available API presentationDimensions

I’m developing a Camera App which uses the presentationDimensions(…) API:

if #available(iOS 13.0, *) {
  let leftVideo = self.formatDescription.presentationDimensions()
  let rightVideo = other.formatDescription.presentationDimensions()
  // ...
}

Now when I try to build the project, I get the following errors:

Undefined symbol: (extension in CoreMedia):__C.CMFormatDescriptionRef.presentationDimensions(usePixelAspectRatio: Swift.Bool, useCleanAperture: Swift.Bool) -> __C.CGSize

Here’s the last Xcode log (error):

Note that when I remove those calls to presentationDimensions everything works fine.

Can anyone help me out here? The API has been available since iOS 13.0, and even if my iOS deployment target is 11.0 I should still be able to build it, no?

    Finally found the answer. I had SWIFT_VERSION pinned to 5.0, but iOS 13 came with Swift 5.2 so pinning Swift to 5.2 (and removing the LIBRARY_SEARCH_PATH pointing to 5.0) solved it.

    That means, this:

                    LIBRARY_SEARCH_PATHS = (
                    ""$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)"",
                    ""$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)"",
                    ""$(inherited)"",
                );
                SWIFT_VERSION = 5.0;

    should look like this:

                    LIBRARY_SEARCH_PATHS = (
                    ""$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)"",
                    ""$(inherited)"",
                );
                SWIFT_VERSION = 5.2;

    In my case I just needed to delete my DerivedData folder contents (~/Library/Developer/Xcode/DerivedData/)

    In my case a function was declared private in my framework and the test target could not see the async method, declaring it internal fixed my issue.
