Error at C:/path/to/notify.component.ngfactory.ts:113:41: Property 'visible' is private and only accessible within class 'NotifyComponent'
... (many more like that with lots of properties from lots of components)
For a given component all its members (methods, properties) accessed by its template must be public in the ahead-of-time compilation scenario. This is due to the fact that a template is turned into a TS class. A generated class and a component are 2 separate classes now and you can't access private members cross-class.
In short: you can't access private members in your templates if you want to use ahead-of-time compilation.
