Hi,
I am testing my application on simulator's safari browser and in that I am downloading a document. When I tapped on the "Download" button on the download alert of Safari it gets crashed. Here actually Safari opens a new window and starts the download but in this specific version iPad Air (3rd generation) its crashing. I tested the same scenario in iPad Pro and there its working fine.
