### Example 7 - Swift - Object Oriented Approach

```swift

// Generate CSV file
let user1:NSMutableDictionary = NSMutableDictionary()
user1.setObject("vignesh", forKey: "name" as NSCopying);
user1.setObject("vigneshuvi@gmail.com", forKey: "email" as NSCopying);
user1.setObject("Hi Vignesh, \nhow are you? \t Shall we meet tomorrow? \r Thanks ", forKey: "address" as NSCopying);

let user2:NSMutableDictionary = NSMutableDictionary()
user2.setObject("vinoth", forKey: "name" as NSCopying);
user2.setObject("vinoth@gmail.com", forKey: "email" as NSCopying);
user2.setObject("Hi Vinoth, \nHow are you? \t Shall we meet tomorrow? \r Thanks ", forKey: "address" as NSCopying);


let data:NSMutableArray = NSMutableArray()
data.add(user1);
data.add(user2);

// Create a object for write CSV
let writeCSVObj = CSV()
writeCSVObj.rows = data
writeCSVObj.fields = ["name", "email", "address"]
writeCSVObj.name = "userlist"

// Write File using CSV class object
let filePath:String = SwiftCSVExport.exportCSV(writeCSVObj);
print(filePath)

// Read File in Object Oriented Way
let readCSVObj = readCSVObject(filePath);

// Use 'SwiftLoggly' pod framework to print the Dictionary
loggly(LogType.Info, text: readCSVObj.name)


```

### Write Output:

```swift

Output: userlist

```
