Failed to initialize an AVAssetExportSession (iPhone XS, XR, XMax)

Question

When I instantiate an AVAssetExportSession object in new simulators instance with either of the 2 methods:

AVAsset *videoAsset = [AVAsset assetWithURL:videoURL];
AVAssetExportSession *exporter =  [AVAssetExportSession exportSessionWithAsset:asset presetName:AVAssetExportPresetHighestQuality];

or

AVAssetExportSession *exporter = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetHighestQuality];

and, run the app on one of the 3 new simulators: iPhone XR, iPhone XS, and iPhone XS MAX, I got exporter = nil, whereas on all other simulators I got a normal non null exporter object.

I also noticed that ONLY when I set the presetName parameter to be AVAssetExportPresetPassthrough, the exporter is not nil. Any other presetName will make the initialization to fail.

Anyone has encountered the similar problems?

Apparently it's an apple bug... https://bugreport.apple.com/web/?problemID=44701489 Will report back once the original bug is closed.

EDIT: This issue has been fixed by Apple in iOS 10.1 SDK. You just update your xcode to 10.1.
