Do not compare to nullptr. We normally prefer the early return first and avoid the else, so this would be:

if (!nativeImage) {
    completionHandler(nullptr);
    return;
}

addResult.iterator->value.first = nativeImage->platformImage();

And here this could be

if (auto nativeImage = image->nativeImageForCurrentFrame())
