Tweakcity . com "injection" trojan on iphone 10?

I SUSPECT THAT THIS IS A TROJAN ON AN IPHONE.  HELP!

I (stupidly) viewed this youtube: How To Cheat In Zoosk On iOS to get zoosk dating website coins free.

https :// www. youtube. com/ watch?v=cyK_p3kRlDw

On the site, it directs you to tweakcity . co to get something "injected" I did.... (I know, don't tell me how dumb that was...)

When you allow it to "inject" its download, it shows a progress % and then disappears. My fear is that it was a trojan. No impact yet, but I won't log into any password accounts on my phone. IOS 13.4.1 iPhone 10. 

ANY THOUGHTS?  Norton Chat Support guy Mejia responded with "Yes I understand, I know that you are worried about the security of your iphone however Apple devices have a strong firewall that won't easily infect by any kinds of threat."

I asked him to escalate to 2nd level but he refused, passing it off as a non-threat. HOWEVER, I DON'T DISMISS THIS. 

ANYONE?
