Alternative to a singleton implementation in Swift?

Question

I'm working on an app which has a ContentManager class. This class migrates files from the bundle, and performs other checks when the app is first opened. It's next used in a ViewController at the end of a rather long chain of ViewControllers. As far as I can tell, there are two methods of implementing this:

1. Instantiate the class in the first ViewController, and pass it through the segues to the final ViewController.

2. Create a singleton sharedInstance in the first ViewController and access it where needed using that sharedInstance.

It seems a lot cleaner and simpler to create the singleton. However, I've read a lot about how singletons are bad. I'm wondering if I'm missing some alternative way of doing this without using a singleton or messily passing the instance through all the view controllers?

Many thanks
