iOS UUID deprecated corebluetooth

Question

I am modifying an app that discovers a device via Bluetooth BLE in order to plot the values into a graph. It all works fine (thanks to the help of one of you in the past week). The app was initially written by my husband a while ago and during the discovery of the device, he was using checking code like :

NSLog(@" Failed to Connect to Peripheral : %@   with UUID: %@   ", peripheral, peripheral.UUID);

or

NSLog(@" Connected to Peripheral : %@   with UUID: %@   ", peripheral, peripheral.UUID);

In front of each of these lines (and some more) I get the warning messages that UUID is deprecated: first deprecated in ios 7.0 Since quite a while, I try to find out by what it has been replaced, but on Google, it doesn't look like other people have the same problem and when I go to the Apple Documentation : here

there is no mention of it being deprecated.

I don't understand...

Could somebody please help ? Thanks

EDIT: ADDING SOME INFO

This is what I get on my computer on the console

Update

I have double checked and the UUID property on CBPeer is also deprecated.

From the docs in Xcode I found -

Deprecation Statement
Use the identifier property instead.

And if you use peripheral.identifier.UUIDString you don't get a deprecation warning.
