Enable "Developer" inside the "Settings" app on iOS
The devices tab is now a new screen. Use for Development no longer exists.
The option in Window → Devices or ⇧⌘2.
From that window you could enable devices for development by adding your provisioning profiles. Right click on device and select Show Provisioning Profiles.... It will appear a window where you can add your profiles.
After that you will be able to install your apps in that device.
We just need to run our application on the connected device using xcode.
I got it on on my iPhone 6 with iOS 9.2 version by running a demo application from Xcode 7.2.
