val daily = dailyForecast.map { convertDayFromDomain(id, it) }

Where does the id come from?

It comes from the forecastList that is passed to with:

I'm in Android Studio 3.01... the program can't seem to find RecyclerView

Even copying and pasting the code from the git returns that RecyclerView cannot be found, and if you type import.android.support.v7.widget.RecyclerView, it doesn't autocomplete, nothing even close under widget... was it removed by chance?
Oddly, adding a RecyclerView to activity_main.xml works fine...

[Mnemoth42]

Ok... anybody who gets this problem, add the following to your build gradle (the app one):
implementation 'com.android.support:recyclerview-v7:26.1.0'
(You might have to change the version to match your current sdk). Once I did that, it worked. Go figure.

Yeah, to use the recyclerview you need to add that support library. It's explained at the beginning of chapter 5:

Was that your problem, or did you have to add also that line to make it work? In the past I've found myself having issues to get that library detected, solved by doing several project cleans.

I followed your book step by step till chapter 15, and I tried to run the app on my Nexus 5.
I got an empty screen.
