The following code runs fine on iPhone with iOS < 18

However with iOS 18 (Release Candidate) it causes a crash of the extension


extension MessageFilterExtension: ILMessageFilterQueryHandling, ILMessageFilterCapabilitiesQueryHandling {
    @available(iOSApplicationExtension 16.0, *)
    func handle(_ capabilitiesQueryRequest: ILMessageFilterCapabilitiesQueryRequest, context: ILMessageFilterExtensionContext, completion: @escaping (ILMessageFilterCapabilitiesQueryResponse) -> Void) {
        let response = ILMessageFilterCapabilitiesQueryResponse()
    response.promotionalSubActions = [ILMessageFilterSubAction.promotionalOffers]
    completion(response)
    }

The problem specifically is the line:

    response.promotionalSubActions = [ILMessageFilterSubAction.promotionalOffers]

Attempting to set a promotionalSubAction (or a transactional sub action) results in an exception with error:

'/usr/lib/swift/libswiftIdentityLookup.dylib' (no such file)`

This only occurs with iOS 18, and it doesn't occur if no subactions are set
