推荐答案

在SwiftUI中，目前我们无法直接更改 navigationBarTitle 字体，但是您可以像这样更改NavigationBar的外观，

In SwiftUI, at this point we can not change the navigationBarTitle font directly, but you can change navigationBar appearance like this,

struct YourView: View {
    init() {
        //Use this if NavigationBarTitle is with Large Font
        //UINavigationBar.appearance().largeTitleTextAttributes = [.font : UIFont(name: "Georgia-Bold", size: 20)!]

        //Use this if NavigationBarTitle is with displayMode = .inline
        UINavigationBar.appearance().titleTextAttributes = [.font : UIFont(name: "Georgia-Bold", size: 20)!]
    }
    var body: some View {
        NavigationView {
            Text("Hello World!")
            //.navigationBarTitle("TEST")
            .navigationBarTitle (Text("TEST"), displayMode: .inline)
        }
    }
}

我希望它能对您有所帮助.谢谢！
