I have a list of matches and when I type in the filter (TextField) it works fine. I also have a list of players the user can pick from. When they choose a player the func playerFilterChanged is called and usernameSearch is updated from the viewModel. I put a breakpoint on matches.nsPredicate = ... in the TextField onChange event and it is hit but the list doesn't update. Am I binding something incorrectly?
struct MatchHistory: View {
@EnvironmentObject private var viewModel: ViewModel

private var matches: FetchedResults<Match>
@Binding var showMatchHistory : Bool
@Binding var showChangePlayer : Bool
var cellPadding : CGFloat = 5
var deviceType = UIDevice.current.userInterfaceIdiom
@State private var orientation = UIDeviceOrientation.unknown
@State var showLoadingMessage : Bool = true
@State private var usernameSearch = ""
func playerFilterChanged(){
usernameSearch = viewModel.filterPlayerName
showChangePlayer = false
}
