Our app was building fine till Xcode 12 beta 2. But since beta 3 all the Xcode version just crashes whenever I try to build the project. Not able to build for simulator as well as devices. I saw similar issue discussed on swift forum where, recommended setting is to remove valid_arch. I tried that solution, but it doesn't work for me.
Spent more than 2 weeks behind this. It will great help if anyone can help here.
