Hi， guys。 When I used SwiftUI to build the app, I used a custom font in the project to display emojis (the font ttf file has 23.7M). When using custom fonts, the code is as follows: ContentView will load slowly。 struct ContentView: View { var body: some View { NavigationView { List { ForEach(0..<100, id: \.self) { i in Text(verbatim: "\u{1fa84}") .font(.custom("NotoColorEmoji", size: 18)) .foregroundColor(.secondary) } } .frame(height: 400) } } } It takes about 3 seconds for the app to start and display the page. If commented out .font(.custom("NotoColorEmoji", size: 18))， everything will be fine So how to improve performance or preload the ttf font file? I wrote a demo in here，Is there any good way to solve this problem?
