UIKit is fantastic. In a few hours I have a gorgeous and super fast UICollectionViewLayout subclass that displays 20000+ items in a table with sticky columns and row headers. I'm glad I'm not too rusty with UIKit. Bye-bye, SwiftUI Table, you're unfinished.
@groue did you use SwiftUI for the cells themselves or would it kill the performance ?
@Hugo_say I don't need to! Plain default configuration with text values.
