Go to Contacts and choose "Move device contacts to". You should be able to see two options - a Google Account and your device account . Choose Google Account and your contacts will be merged with it. And then log in your google account on XOLO and sync the contacts.
If you don't want to use this way,more easier method is to use 3rd party data transfer tool,that can help transfer contacts between iPhone and XOLO directly.

Maybe the phone data manager can allow you to transfer everything between different or same two phone
