numberOfRowsInSection Error

Hello. I try to create simple Android/iOS app with TableView. For Android it works fine, but when I try to launch iOS AndroidStudio returns error: -[MyViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x7f…

What I do wrong?

Dear Dan,

Could you please share your code? It is hard to help without actually seeing what you are trying to run.

Best Regards,

I use this tutorial. But with RXJava2 and Retrofit2. All works fine besides numberOfRowsInSection error.
