I am using FireStore too, a lot of warning that comes from FS depencencies, but what it is annoying is that previews not working at all. Running on phone emulator works as expected, but making UI changes are not displayed in preview. Below is the error that is showing up and i have no clue what to do here or how to fix it. The arm64 thing all over other sites doesn't work for me. Error Domain=FBProcessExit Code=1 "The process exited voluntarily."
