Summary: In iOS 10 GM, QLPreviewController fails to reliably render xls files. See the screenshots above comparing the sample app (attached) with the iOS 8 and iOS 10 versions of QL. The bug results in the cell grid not properly rendering in cases depending on whether or not there's data in the cells. Steps to Reproduce: 1. Unzip QuickLook.zip 2. Open QuickLook.xcodeproj 3. Build and run for the iOS 10 simulator. 4. Observe artifacting in with both files (grid1/grid2.xls) 5. Build and run for the iOS 8/9 simulator (your choice!) 6. Observe proper behavior Expected Results: I would expect the grid to render properly, to best represent Excel's output. Actual Results: The grid does not render properly. See ios10-grid1/grid2 screenshots. Version: iOS 10.0.1 [14A403] Configuration: Any device that runs iOS 10, or the simulator is sufficient.
