After moving all the non-view logic into the presenter, the next step is to move those groups of logic into their own respective layers. Most of these Layers are going to be below a Model Layer. The Model Layer's responsibility is to use the different Data Layers (Network, Database, Translation) and return the result - it just simplifies what the presenter needs to ask for. The presenter's responsibility is to ask for the data, apply any specific business transformations on that data, and hand it to the view layer.
- [Instructor] We've moved out of the logic…into the presenters,…and now the next step is to move that logic…into the real layers that it belongs to.…The networking code in the networking layer,…the database code in the database layer,…and any translation stuff within a translation layer.…So, the first thing we're going to do is create classes…to put those in, and groups to put those classes in.…So within our model layer,…we have a network in a database layer.…Let's create a group,…and we'll name this Translation.…
And in here, we're going to create a translation layer.…So New File, it's a Swift File,…and we'll just say TranslationLayer.…And in here we'll say class TranslationLayer.…We'll also do this for the Database.…Say New File, Swift File, and DatabaseLayer,…class DatabaseLayer,…and also the Network Layer, NetworkLayer,…class NetworkLayer,…and then we'll make a model layer,…which all of those other pieces will belong to.…
Now that model layer could be your interactor,…it could be a model manager,…you could call it whatever you want,…
