I'm not sure where you got this from?
It is certainly not incorrect to use the dot syntax if there is not a declared property.

The introduction states:
"Objective-C provides a dot (.) operator that offers a compact and convenient syntax you can use as an alternative to square bracket notation ([]s) to invoke accessor methods."


Declared Properties are mentioned later:
"Accessing a property property calls the get method associated with the property (by default, property) and setting it calls the set method associated with the property (by default, setProperty:). You can change the methods that are invoked by using the Declared Properties feature (see “Declared Properties”)."
