Hybrid classes and multi-classing in parent class?

[FallzQuick]

Can I pick a hybrid class and multi-class into one of their parent classes?

for example: Swashbuckler - parent class: fighter, gunslinger.

could i have a level of fighter and swashbuckler?

I read that alternate classes like rogue/ninja it is not allowed, however did not se anything about hybrids.

Yes.

During the playtest multiclassing like that wasn't allowed, but that prohibition was dropped from the final text.

Hybrid Classes wrote:

Each one of the following classes lists two classes that it draws upon to form the basis of its theme. While a character can multiclass with these parent classes, this usually results in redundant abilities. Such abilities don't stack unless specified. If a class feature allows the character to make a one-time choice (such as a bloodline), that choice must match similar choices made by the parent classes and vice-versa (such as selecting the same bloodline).
