It feels weird to call the whole folder alert_coordinator, as it is only one
specialization of the more generic alert_controller_coordinator. What about just
alert_controller?

See new names.

+
+// Coordinator to display a standard alert (popup) to the user.
+@interface AlertCoordinator : AlertControllerCoordinator
+
+// Initializes with the alert title.
+- (instancetype)initWithViewController:(UIViewController*)viewController

Why loosing the "Base"? 

[gambard, 2016/07/07 08:57:43]

Changed.

+                                 title:(NSString*)title;
+
+// Title is mandatory.
+- (instancetype)initWithBaseViewController:(UIViewController*)viewController
+    NS_UNAVAILABLE;
