Access variable in the same class in Swift

Question

Currently, I want to write a APIEndpoint class with contains all of my APIs. I have a variable baseURL and I want to use it for the remains. But when I tried to write it as below, it comes to error.

class APIEndpoint {
    static let shared = APIEndpoint()
    static let baseURL = "https://13.251.102.94:5001/api/"
    static let login = URL(string: baseURL + "auth/customer/login")!
}

My function

func performLogin () {
        var request = URLRequest(url: APIEndpoint.shared.login)
        request.httpMethod = "POST"
        let json: [String: String] = ["username": self.name, "password": self.password]
        request.httpBody = try? JSONSerialization.data(withJSONObject: json)
        Network.shared.session.dataTask(with: request) { (data, response, err) in
            guard let data = data else { return }
            print(JSON(data)["data"])
        }.resume()
}

Error:

Static member 'login' cannot be used on instance of type 'APIEndpoint'

in line: var request = URLRequest(url: APIEndpoint.shared.login)

URLRequest(url: APIEndpoint.login) should work. The issue is that APIEndpoint.shared is a specific APIEndpoint instance, like you do: let specificOne = APIEndpoint.shared, it can't use a static` method then. — Larme

@CôngToànLê Also. for future reference, if you want to reach something through your singleton, you don't need to make the other values inside your singleton static as well. It's enough with having the shared static to reach the other values — Vollan

login and baseURL are static members of class APIEndpoint. You're already could use them as APIEndpoint.login and APIEndpoint.baseURL. In your case you should write

var request = URLRequest(url: APIEndpoint.login)
