It is possible to share screen on Skype on the desktop version for Windows and macOS from the last few years. Recently Skype expanded this setting to Skype for mobile. With Skype 8 mobile app, you can stream the display of your Android device or iPhone or iPad to your contacts. All you need is to open the Play Store or App store and download the upgrade for your Skype installation and make a call.
Share screen on Skype for iPhone and Android
Remote access and screen sharing are already possible in mobile devices with TeamViewer. However, this feature not widely used among iPhone and Android mobile phone users, probably because of the platform limitations. But it might get more takers as Skype rolls-out the option to share screen. When you have cross-platform video capabilities and IM, screen sharing is a lot more useful on Skype.
1: Download latest version of Skype app for Android, here or iPhone, here.
2: Make a video/audio call on Skype between the two devices you want to share the screens.
3: When the call starts, tap on the phone display, and find the three dots on the right side.
4: Take the option to “Share Screen” and press Continue/Allow if a warning pop-ups.
You may minimize the Skype window at this point, and go to the home screen of the device or any other section which you would like to share with your chat-mate.

The screen casting on Skype works in such a way that the device from which you start the above process act as the host.
