如何在SwiftUI中为一个导航链接设置多个目的地

Question

我想为一个基于布尔值的导航链接获取多个目的地。我怎样才能做到这一点？

HStack {
Spacer()
NavigationLink(
destination: isSignUpView == true ? SetupPassView() : ForgetView(),
isActive: $showSetupPassView,
label: {
Button(action: {enterEmailApi()}, label: {
NextButtonView(isAnimating: $showLoading)
})
})
}

我得到这个错误：

Result values in '? :' expression have mismatching types 'SetupPassView' and 'ForgetView'

})
})
} else {
