    let title: [String] 
}
struct Business: Decodable {

First thing's first. Let's fix your struct names. struct declarations should be CapitalizedCamelCase, so your struct looks like this:

struct Categorie: Decodable{
    let title: [String] 
}
struct Business: Decodable {
    let name: String = ""
    let categories: [Categorie]
}

Next, you're looking for the title property of an element in the array of categories, so you'd do it like so:

business.categories[0].title

You need to specify which element of the array you want to examine. In the example above, I'm getting the 1st element's ([0]) title property. You'll want to put some logic in to protect against categories being empty.
