首先下載Safari Technology Preview版本
Using Safari 11.1, I got the inspector working by
1.Opening the project in xcode 9.2.
2.Build and Run app from xcode,
3.Waiting for Simulator to start then wait for the app to open.
4.Opened Safari, could see simulator in the "Develop" menu,Select the running tvOS app from under the simular.
If you can't see your app try doing the below
1.Restart Safari.
2.Ensure you can navigate to the page in safari.
3.Do a clean on the xcode project.
4.Restart your Mac.
