Timer or Pomodoro?
PG 54...
def start_stop_timer(sender)
if @pomodoro_timer.nil?
PG 56...
def start_stop_pomodoro(sender)
if @pomodoro_timer.nil?
PG 58...
The last item we need to connect is our start_stop_pomodoro action

Connecting Our Controller to Our Interface
May want to give a quick blurb as to why we are grabbing and dragging "Object" from the library to the App window and setting"Object" properties to "PomodoroController". And why we are not using "Object Controller" for this since it appear right under "Object". This may leave some readers scratching there head and wondering.

page 11.
Message passing is
......
runtime, whereas message calling will call the method directly without doing a check.
.....
This is one of the reasons why languages like Smalltalk, Objective-C, and Ruby are
considered to be dynamic
I think the message calling may should be method calling?

A few details that I noticed as I worked through the examples, etc:
Section 3.3.3 references a figure 3.13 (which is not the right figure). It appears that a figure may have been dropped?
Your final source code solution in Listing 3.2 shows an attr_accessor of :create_button that is not needed. It seems to have been omitted earlier because it's not discussed as you go through the example, and also does not appear in your figure 3.15.
A suggestion on the Pomodoro app? While the focus is on the introduction of the new technology, your implementation could be "cleaner". For example, you set the "default" time to 25 minutes in multiple locations instead of setting it in one place and referring to it throughout your code.
Overall, really enjoyed reading the chapters you have developed, and look forward to the future updates!

Page 6: Message Passing twice.
Both languages provide a dynamic runtime, message passing, runtime access to class and object information, meta classes, and message passing to name a few.
