If you see the message “iPhone Unavailable” it means that you have entered an incorrect passcode too many times and your iPhone is now locked. This is a security measure to protect your data, and if you enter the wrong passcode seven times in a row, you will be locked out for at least five minutes.
Put your unavailable iPhone in recovery mode first, then connect it to iTunes on your computer. iTunes will pop up a message window. Then go with the restore option. Then your iPhone gets restored in a few minutes.
Make sure Bluetooth is turned on. Touch and hold Bluetooth . In the list of paired devices, tap a paired but unconnected device. When your phone and the Bluetooth device are connected, the device shows as "Connected."
On your iPhone, go to Settings > [your name] > Find My. If you're asked to sign in, enter your Apple ID. If you don't have one, tap “Don't have an Apple ID or forgot it?” then follow the instructions. Tap Find My iPhone, then turn on Find My iPhone.
Before you debug with iPhone, follow this mapping table about the version of Xcode and iOS：
Xcode 12.3 → iOS 14.3
Xcode 12.2 → iOS 14.2
Xcode 12.1 → iOS 14.1
Xcode 12 → iOS 14
Xcode 11.7 → iOS 13.7
Xcode 11.6 → iOS 13.6
Xcode 11.5 → iOS 13.5
Xcode 11.4 → iOS 13.4

If you're still encountering the error, try to unpair the device within the menu Window > Devices and Simulators, clean Xcode, reconnect and trust the device, then re-run. It worked for me!

Xcode 11.4 includes SDKs for iOS 13.4 as mentioned on the release notes here.
You must update to the beta version if you wish to deal with iOS 13.5.
Developers who are using Xcode 11.5 and trying to install their app in iOS 13.6 device will also see this message. It's a very confusing message.
All you need to do is Download Device support files of iOS 13.6 from this link
filsv/iPhoneOSDeviceSupport
Close Xcode
Unzip and paste it in this location:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
Reopen Xcode.
Now you can install the app on the iOS 13.6 device using Xcode 11.5.
Well, to be able to even get some information about why this happens, I did this:
Going to Window → Devices and Simulators will give you a better idea of what's going on. In my case, I had to update the iPhone since Xcode updated overnight and stopped supporting my iPhone.
Check your iOS Version from (Settings → General → About → Software Version) and get the device support file from the link below:
https://github.com/iGhibli/iOS-DeviceSupport/tree/master/DeviceSupport
Next, unzip the files and place them at the following location:
Applications → Xcode → right click → Show Package Contents → Contents → Developer → Platforms → iPhoneOS.platform → DeviceSupport
**Restart your Macbook or pc **
after restarting xcode will configuring and ready to install your app app in your iPhone which is running on higher ios version.
Xcode 11.4 does not support the new iOS 13.5. Updating to Xcode 11.5 fixed the issue for me
