Swift - Cannot convert value of type 'Any?' to expected argument type 'String'

Question

if let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
    
    if let nickn = json["nickname"] as? String {
        if(nickname != nickn){
            nickname = nickn
        }
    }
    
    var serverScalingString = ""
    serverScalingString += "0," + json["srvFile0"] as? String + "|"
    
    serverScaling = serverScalingString
    
}

I get "Cannot convert value of type 'Any?' to expected argument type 'String'" on

serverScalingString += "0," + json["srvFile0"] as? String + "|"

I don't need any null safety on the string json["srvFile0"] , if this would be null then the app can just crash

changing as? to as! doesn't work

Please help

Answer 1

I solved it like that:

serverScalingString += "0," + (json["srvFile0"] as? String ?? "") + "|"
