BTW, why do you keep a pointer to that controller?

Removed. 
I was going to start working on this file but thought I just add it for now and
leave its implementation for a different CL. So this is a leftover, will remove!

+@end
+
+@implementation SCToolbarCoordinator
+@synthesize baseViewController = _baseViewController;
+@synthesize viewController = _viewController;
+
+- (void)start {
+  self.viewController = [[ToolbarViewController alloc] init];

The toolbar doesn't set its own height; it relies on the view controller
presenting/containing it to do that. So you might want to set
self.viewController.view.frame.size.height to something reasonable here so the
toolbar looks like a toolbar.

Sorry for not being clearer (Though this feedback helps me anyways). I was
intending for this CL to only add the application State and the basic files.

 I was thinking on working on the implementation of this file on a different CL,
to keep things simple. Should I add it here? 

[marq (ping after 24h), 2017/01/25 09:29:22]

That's fine. Small CLs are good!

+  self.viewController.title = @"Toolbar";
+  [self.baseViewController pushViewController:self.viewController animated:YES];

You should add a protocol alerter for <ToolbarCommands> and set it as the
ToolbarViewController's toolbarCommandHandler.

Ditto.
