在添加navigationBarItem时,是这么写的:
.navigationBarItems(trailing:
PresentationButton(destination: ProfileHost()) {
Image(systemName: "person.crop.circle")
.imageScale(.large)
.accessibility(label: Text("User Profile"))
.padding()
}
)
按照上面的写法会有警告提示!

查看官方 完整版的demo,依旧有警告,改成下面的代码就好了.
.navigationBarItems(trailing:
PresentationButton(
Image(systemName: "person.crop.circle")
.imageScale(.large)
.accessibility(label: Text("User Profile"))
.padding(),
destination: ProfileHost()))
}
