Ios find app package and app activity

Hi Team,
I am new to ios automation using appium.
Please let me know how we can find app package and app acitvity for ios.
Application is not getting tested in android.

You need to have the app file on your computer. the extension is .ipa
Unfortunately for ios, it doesnt have the capabilities for appActivity and appPackage like Android has. It is set as app instead. Refer Appium documentation regarding desired capabilities : http://appium.io/docs/en/writing-running-appium/caps/index.html
