能否通过Apple内置Sheet实现全屏NavigationStack视图跳转？

你要的这种交互完全能用Apple原生Sheet实现，核心是换一种视图触发方式，而不是死磕navigationDestination：

最优实现方式：用fullScreenCover触发全屏视图 #

直接在Sheet的内容视图里通过fullScreenCover来弹出全屏新视图，关闭后会自动回到原Sheet，和Instagram、TikTok的逻辑完全一致：

struct ContentView: View {
    @State private var showSheet = false
    @State private var showFullScreenView = false
    
    var body: some View {
        Button("打开评论Sheet") {
            showSheet = true
        }
        .sheet(isPresented: $showSheet) {
            CommentSheetContent(showFullScreenView: $showFullScreenView)
        }
    }
}

struct CommentSheetContent: View {
    @Binding var showFullScreenView: Bool
    
    var body: some View {
        VStack {
            Button("查看用户资料") {
                showFullScreenView = true
            }
        }
        .fullScreenCover(isPresented: $showFullScreenView) {
            UserProfileView()
        }
    }
}

struct UserProfileView: View {
    @Environment(\.dismiss) private var dismiss
    
    var body: some View {
        VStack {
            Text("用户资料页")
            Button("返回评论Sheet") {
                dismiss()
            }
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(.white)
    }
}

备选方案：基于导航栈的全屏布局 #

如果需要保留导航栏交互，可以把Sheet内容嵌入NavigationStack，同时让目标视图占满全屏：

struct CommentSheetContent: View {
    @State private var navigateToProfile = false
    
    var body: some View {
        NavigationStack {
            VStack {
                Button("查看用户资料") {
                    navigateToProfile = true
                }
            }
            .navigationDestination(isPresented: $navigateToProfile) {
                UserProfileView()
                    .frame(maxWidth: .infinity, maxHeight: .infinity)
                    .background(.white)
                    .navigationBarBackButtonHidden()
            }
        }
    }
}

这种方式下，新视图会铺满整个屏幕，关闭后回到Sheet的导航栈中，同样能满足需求。
