Solution to this bug is to implement the callback and call super:

  // Occasionally called by iOS, even though init(task:...) is implemented. Will cause a crash if not present.
  override init(request: URLRequest, cachedResponse: CachedURLResponse?, client: URLProtocolClient?) {
     super.init(request: request, cachedResponse: cachedResponse, client: client)
  }
