Is it possible to output userinput to a .csv using swift?

Question

I am very new to learning to code in Swift. I am trying to make an application that keeps a list of people who are coming in. I want it to log the name they input, time of visit, and the nature of their visit. However, I want this to be able to be exported to a program like Numbers or Excel. I have found some info on storing the inputs from the user but those seem to get deleted if the app is closed. I can't seem to find any other info, but perhaps I'm just searching the wrong info. Any help or guidance is appreciated.

Before you worry about exporting your data in some other format, you should focus on getting your app to keep the data that is entered. — rmaddy, Jun 26 '18 at 16:02

Just store your log in a Array and then with this function you safe it to a .csv file.

func saveCSV(_ name : String,_ customUrl : URL) -> Bool {

    let fileName = "\(name).csv"
    let b = customUrl.appendingPathComponent(fileName)


    var csvText = ""
    var id = "1"
    var name = "test"
    csvText = "ID,Name\n"
    let newLine = "\(id),\(name))\n"
    csvText.append(newLine)

    //or create a loop
    // Task is my custom Struct
    var array : [Task]
    for task in customArray {
        let newLine = "\(task.ean),\(task.menge),\(task.name)\n"
        csvText.append(newLine)
    }

    do {
        try csvText.write(to: b, atomically: true, encoding: String.Encoding.utf8)
        return true
    } catch {
        print("Failed to create file")
        print("\(error)")
        return false
    }
}

func createDic()->URL?{
            let documentsPath1 = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])
            // CSV is the folder name
            let logsPath = documentsPath1.appendingPathComponent("CSV")
            do {
                try FileManager.default.createDirectory(atPath: logsPath!.path, withIntermediateDirectories: true, attributes: nil)
                return logsPath
            } catch let error as NSError {
                NSLog("Unable to create directory \(error.debugDescription)")
            }
            return nil
        }

var customUrl = createDic()

and now you can call it :

 if saveCSV(userList, customUrl){
print("success")
}

and after this you can do what you want with the .csv file
