“guard let snmpSender = SnmpSender.shared” does not work. The “fatalError” is always thrown. According to the documentation of the “SwiftSnmpKit” framework, this is a singleton. Here is the code:

import Foundation
import SwiftSnmpKit

public class SnmpMachine {
    private init() {
        
    }
    static func run(agent: String, userName: String, pduType: SnmpPduType, oid: String, password: String, privatePassword: String) async {
        
        
        guard let snmpSender = SnmpSender.shared else {
            fatalError("Snmp Sender not inialized")
        }
        
        

        let result = await snmpSender.send(host: agent, userName: userName, pduType: pduType, oid: oid, authenticationType: .sha1, authPassword: password, privPassword: privatePassword)
            
        switch result {
        case .failure(let error):
            print("SNMP Error: (error.localizedDescription)")
        case .success(let variableBinding):
            print(variableBinding)
        }
    }
}

The code I use here comes directly from the documentation of the framework. Unfortunately, I don’t have any direct ideas as to why it doesn’t work (I’m a beginner). But does the ‘shared’ property perhaps not exist?

Thank you in advance for your help!
