That may be possible, by converting the scenes in each project as addressable assets and then downloading it through the button calls in native. Never tried though!

You can use UICollectionViewDelegateFlowLayout      // Compute the dimension of a cell for an NxN layout with space S between     // cells. Take the collection view's width, subtract (N-1)*S points for     // the spaces between the cells, and then divide by N to find the final     // dimension for the cell's width and height.    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout,	 	 sizeForItemAtindexPath: IndexPath) -> CGSize {     		let cellsAcross: CGFloat = 1      let spaceBetweenCells: CGFloat = 1     let dim = (self.cvImageViewer.bounds.width - (cellsAcross - 1) * spaceBetweenCells) / cellsAcross      return CGSize(width: dim, height: self.cvImageViewer.bounds.height)   } This solved the issue for me
