My phone cant find the wifi module esp8266

So i was watching this tutorial How to control LED through Android Mobile phone App Using ESP8266 RemoteXY - YouTube and everything was okey, i have the exact same thing that the guy has in the video, but the problem is that when i try to connect on settings the wifi module it does not appear, im very confuse and i dont know why is not there.

Im using IOS iphone 8 plus

Does anybody know how can i solve this?

How can you say that everything is OK if you don't see the ESP module?

What software do you have on the Arduino? What software do you have on the ESP module?

Don't expect us to view the complete video to find out what that guy have done just to even not knowing then what you've done exactly. Provide a step-by-step explanation of what you've done so we know how your setup is.

Post links to the sites where you bought the hardware!
