Naming init parameters

:  ~ 45 sec read

I used to name them by the type of the parameters passed in, for example:

let dictionary = ["name": "Sneakers", "price": "40"]
let product = Product(dictionary: dictionary)
let viewModel = ProductViewModel(product: product)

But lately, I've been using a more Swifty approach, by having an external name of from or with:

let dictionary = ["name": "Sneakers", "price": "40"]
let product = Product(from: dictionary)
let viewModel = ProductViewModel(with: product)

How do I pick between the two? I go with the following approach:

In our example above, the product is a model, and models are usually created entirely from a dictionary (a JSON), while the viewModel might have other properties, like numberOfSections & numberOfRows for a tableView or buttonTitle - "Buy" or "Sold Out", for example.

Is the difference too subtle and not worth stressing over? Or does it slightly imrpove the semantic? Let me know what you think @rolandleth.
