I tested in some conditions...
I coded some Lists that is getting image datas from firebase URL and they have no problems.
but After I made a LazyVGrid in ScrollView that is getting images from the same firebase server, whenever I scroll some amount then app crashes...
I tested some local images to LazyVGrid then it's ok. but whenever it downloads images in realtime and scrolling cause crash(app stops. no error messages...)
I think this is SwiftUI Bug...
