    let topInset = CGFloat(20)

    let bottomInset = CGFloat(20)

    let leftInset = CGFloat(20)

    let rightInset = CGFloat(20)

    

    override func drawText(in rect: CGRect) {

        let insets: UIEdgeInsets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)

        super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))

    }

    

    override public var intrinsicContentSize: CGSize {

        var intrinsicSuperViewContentSize = super.intrinsicContentSize

        intrinsicSuperViewContentSize.height += topInset + bottomInset

        intrinsicSuperViewContentSize.width += leftInset + rightInset

        return intrinsicSuperViewContentSize

    }

Reading data from Local Json file using Alamofire in swift3

//Reading data from Local Json file instead of Service urls using Alamofire in swift3

func getwordmeaningdata()

  {

   

    if let path = Bundle.main.path(forResource: "localfile", ofType: "json") {

       let url=URL(fileURLWithPath: path)

        Alamofire.request(url).responseJSON { response in

            

            if let JSON = response.result.value {

                print("JSON: \(JSON)") 

            }

        }

}


//This is the data of local json file not getting from URL
localfile.json

{

  "person":[

    {

      "name": "Bob"

     

    },

    {

      "name": "Vinny"

      }

]

}

Read data from textfile in swift 3

let path = Bundle.main.path(forResource: "textfile", ofType: "txt")

 print(path!)

                

let url = URL(fileURLWithPath: path!)

 print(url)

                

 let contentString:String = try! String(contentsOf: url, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue))

//if convert to Data

 let data = contentString.data(using: String.Encoding(rawValue: String.Encoding.utf8.rawValue), allowLossyConversion: false)!

                        

print("string\(contentString)")

Localization in swift 3

step 1 : Add the Language

-->file will added like above image

Step - 2 : Add the String file

create String file and rename it as "Localizable.strings"

Step 3 : Configure String file for Localization

Step - 4 : Add the key values to get the value

note: we may check files are created in currect format or not by using cmds

1. cd into your project root
2. cd en.lproj - you can replace this with any localisation you are working with.
3. plutil -lint Localizable.strings

step - 5:

we can switch the language on buttons like

  @IBAction func english(_ sender: Any) {

        

        let path = Bundle.main.path(forResource: "en", ofType: "lproj")

        let bundel = Bundle.init(path:path!)! as Bundle

   countryName.text=bundel.localizedString(forKey: "usernametitle", value: nil, table: nil)

    }

    //pt-PT.lproj

    @IBAction func protual(_ sender: Any) {

        let path = Bundle.main.path(forResource: "pt-PT", ofType: "lproj")

        let bundel = Bundle.init(path:path!)! as Bundle

        countryName.text=bundel.localizedString(forKey: "usernametitle", value: nil, table: nil)

    }



change forResource string based on language
