Help me clear up some confusion?

Assalmualaykum guys. I have started learning Arabic recently, and I'm learning Khaleeji (gulf) arabic. The first phrase my teacher taught me was how to say "what is your name". He said it's "ish asmak" إيش اسمك. But online, people saying that it's not this it's something else. I'm so confused. Is this correct or incorrect?
