How do you implement a RequestAdapter in Alamofire 5?

Question

In the Alamofire 5 Beta, SessionManager has been replaced by Session. I am wondering what the procedure is now for assigning a RequestAdapter, as this was a var in Alamofire 4, but in Alamofire 5 it's now a let constant. Hence the following code:

var session = Session()
session.adapter = AccessTokenAdapter

throws a compile-time error, "Cannot assign to property: 'adapter' is a 'let' constant"

The end goal is to set custom header fields such as JWT token.

You should conform to 'RequestInterceptor' protocol in your class, which have identical methods:

adapt and retry as in RequestAdapter and RequestRetrier.

Then you just pass it to request:

AF.request(urlRequest, interceptor: RequestInterceptor? = nil)
