Thanks for explanation. Maybe I will try different approach then, because I am not experienced enough to use something like RxSwift and RxCocoa for biding. In one tutorial I saw that viewModel was basicly just mapped struct from model to set up view in cell, and controller was downloading data, link to video: [ [this video] ] .

If you want the pure MVVM implementation put it in the view layer because cell height belongs to the how the cell should display and it is a pure view logic, but it is acceptable to some extent you can put some view related code in the ViewModel.

A youtube video I stumbled upon considers the class as the view: [this video] Edit: To clarify the question: Which one of the following is the view and controller? Are both considered the view? CustomUITableViewCell.xib CustomUITableViewCell.swift
