If you are using Alamofire 4.0 or greater, you can use RequestAdapter protocol to intercept the request and inject the JWT token. This solution is perfect if you make many requests and have to use JWT in each of them.

class AccessTokenAdapter: RequestAdapter {
    private let accessToken: String
    private let prefix: String

    public init(accessToken: String, prefix: String) {
        self.accessToken = accessToken
        self.prefix = prefix
    }

    public func adapt(_ urlRequest: URLRequest) throws -> URLRequest {
        var urlRequest = urlRequest

        if let urlString = urlRequest.url?.absoluteString, urlString.hasPrefix(prefix) {
            urlRequest.setValue("Bearer " + accessToken, forHTTPHeaderField: "Authorization")
        }

        return urlRequest
    }
}

Somewhere in the class you initialize the SessionManager like this:

var sessionManager = SessionManager()
sessionManager.adapter = AccessTokenAdapter(accessToken: token, prefix: "https://protected.api.com")

And you use it whenever you want to:

sessionManager.request(MyRouter.getCustomData()).responseArray { (response: DataResponse<[CustomData]>) in

        if response.result.isSuccess {
            self.array = response.result.value ?? []
        } else {
            print(response.debugDescription)
        }
    }
