Screenshot images for iPhone app

If it is available, can someone please guide me to it’s location ?
If i want to upload an app to android, i have the APK so i can screenshot pages from my mobile after installing the build.
But how can i provide the screenshots for the iPhone app ?

Thank you

On a Mac you can run it on the Xcode simulator. This app let’s you simulate different iOS devices and take screenshots of it.
You could also use a real iOS device for this, too.

If you are on Windows, I am not able to answer this for sure, but I guess something similar should be possible using Nowa in local mode. I don’t think, this is Mac-only

Can you tell me in quick words/points how to run it on xcode?

Using this app code on android studio (windows) doesn’t work

Thanks
