Could Not Launch Appium Inspector | Appium Inspector not supporting/working for iOS Native Apps

I have been used the Appium Inspector for identify the elements for Android Native Apps, however I tried the same way for iOS Native Apps to get the elements . The iOS Native Apps was installed in my real devices but inspector window in not open and I got an error message says that

Be sure the Appium server is running with an application opened by using the “App Path” parameter in Appium.app (along with package and activity for Android) or by connecting with selenium client and supplying this in the desired capabilities object.
