Video AVAsset — only saves one object to arrays - ios

Question

I am trying to use implement photo and video functionality to my iOS app with Swift.
Images work fine. The images and uiimages arrays are correctly populated.
With video — it only seems to save one video to the array (i.e. it overwrites the existing video, even though the imageIndex has changed. This happens in both the videos and media arrays).
What could be causing this? It seems I have the exact same logic for videos as for images, and saving images in the media ([AnyObject]) array works fine, but not for videos.
#State var images = [Image?](repeating: nil, count: 6)
#State var uiimages = [UIImage?](repeating: nil, count: 6)
#State var videos = [AVAsset?](repeating: nil, count: 6)
#State var media = [AnyObject?](repeating: nil, count: 6)
...
CaptureImageView(isShown: $showCaptureImageView, uiimage: $uiimages[imageIndex], image: $images[imageIndex], video: $videos[imageIndex], amedia: $media[imageIndex], camera: camera)
.onAppear {
self.disableButtons = true
}
.onDisappear {
var nonNil:Int = 0
for media in media {
if media != nil {
nonNil += 1
}
}
self.nonNilImages = nonNil
self.imageIndex = nonNil
self.disableButtons = false
print("-------")
print("imageIndex: \(imageIndex)")
print(videos)
print(media)
}
