How to Get Account Name from Contact Framework

How to get My Number from AddressBook framework ?

This is not allowed. There is no public API to get user's phone number.
There are few open question on SO that cover this theme. For example this.

Swift Using Contacts Framework, search using phone number to get Name and User Image

In order to get this example up-and-running quickly I used the following sources of info:

Filter non-digits from string

The code block below includes the authorisation check because I had to get it working in order to test in the simulator. The code is just the Single-View Apps view controller and you can connect up a UIButton in the Storyboard to the findContactInfoForPhoneNumber: method to get if to run. Output is to the console - you will need to replace these print statements with something else.

If you are not interested in the full view controller code then just look at the searchForContactUsingPhoneNumber(phoneNumber: String) method. I've followed Apple's advice in the docs to run the CNContact framework asynchronously.

The code strips all the +, - and ( symbols that could be in a phone number and just matches the digits so the phone number you pass in to match MUST be exactly the same.

Contacts Framework. Access to phones ' values

The digits are a private variable.
For getting a phone number:

CNLabeledValue<CNPhoneNumber*>* labeledValue = contact.phoneNumbers[0];
NSString *phone = labeledValue.value.stringValue;

E.g. to get a mobile number:

// get mobile
NSString *phone = nil;
for (CNLabeledValue<CNPhoneNumber*>* labeledValue in contact.phoneNumbers)
{
    if ([labeledValue.label isEqualToString:CNLabelPhoneNumberMobile])
    {
        phoneNumber = labeledValue.value.stringValue;
        break;
    }
}
