Why is callFruit() being called on instantiation?

gettin-called.swift

struct ContentView: View {
    static let fruits = ["apple", "pear", "banana"]

    func callFruit() -> some View {
        print("Getting called!")
        return SomeOtherView(fruit: "apple")
    }

    var body: some View {
        NavigationView {
            List {
                ForEach(ContentView.fruits, id: \.self) { fruit in
                    Text(fruit)
                }
            }.navigationBarTitle("Some Fruits").navigationBarItems(trailing: NavigationLink(destination: callFruit()) {
                Text("Fruit")
            })
        }
    }
}

struct SomeOtherView: View {
    var fruit = ""
    var body: some View {
        Text(fruit)
    }
}
