This time i will report app error to slack using webhook. A webhook in web development is a method of augmenting or altering the behavior of a web page or web application with custom callbacks.
The first thing to do is register your app to slack and following this link https://api.slack.com/

Setup in App

In my case using MVVM pattern, some code that will be displayed is ViewModel and Model . use pod alamofire for hit API

• ViewModel (Function for hit Api to webhook slack)

func getReportErrorToSlack(error: String, lineStr: Int, functionStr: String) {
let baseWebHook = "https://hooks.slack.com/services/xxxxxx/xxxxxx/xxxxxxx"
var blocks = [[String: Any]]()
var attacments = [[String: Any]]()
let block = MyAppModel.Block(username: "user test", errorCode: "404", message: error, line: lineStr, function: functionStr)
blocks.append(block.parameters!)
let attacment = MyAppModel.Attachment(blocks: blocks)
attacments.append(attacment.parameters!)
let parameters = MyAppModel.Request(attachments: attacments)

Alamofire.request(baseWebHook, method: .post, parameters: parameters.parameters, encoding: JSONEncoding.default)
.responseJSON { response in
print(response)
 }
}
// How to use
self.getReportErrorToSlack(error: error.localizedDescription, lineStr: #line, functionStr: #function)

• Model Request

public struct MyAppModel {
    
    public struct Request {
        let attachments: [[String: Any]]
        
        var parameters: [String: Any]? {
            return [
                "attachments": attachments
            ]
        }
    }
    
    public struct Attachment {
        let blocks: [[String: Any]]
        
        func parameters() -> [String: Any] {
            return [
                "color": "#f2c744",
                "blocks": blocks
            ]
        }
        
    }
    
    public struct Block {
        
        var username: String
        var errorCode: String
        var message: String
        var line: Int
        var function: String
        
        var parameters: [String: Any]? {
            return [
                "type": "section",
                "text": [
                    "type": "mrkdwn",
                    "text": "*username:* \n \(username) \n *error_code:* \n \(errorCode) \n *message_error:* \n \(message) \n *line_code:* \n \(line) \n *function:* \n \(function)"
                ]
            ]
        }
        
    }
}
