@IBOutlet weak var webview: UIWebView!


Step - 4
write this code in viewDidLoad()

        let urlobject = NSURL (string: url)
        let request = NSURLRequest(URL: urlobject!)
        webview.loadRequest(request)

Note:
https:// URL ios support very easily because of https is very secure URL. if like to support the only HTTP:// URL than follow this step

first open your Info.plist file and add two permission 


App Transport Security Settings
     Allow Arbitrary Loads    =  YES




code is same only change is HTTPS to HTTP

        let url = "http://myios18.blogspot.in/"
        let urlobject = NSURL (string: url)

Swift   Dictionaries


     Dictionaries are the same array but the array is only store value. dictionaries are store key and value.

      Dictionaries are accessed by key, and key is user defined   
key is unique identifier if you are not using the unique key then at a time access to two value. 

      Dictionaries are very use full and very easy to accessed.




if You are create a empty dictionary using following initializer syntax:

var dictionariesname:Dictionary = [keyType:valueType]()

Example :

var frined:Dictionary = [Int:String]()

if you are create a dictionary with value using following initializer syntax:

var dictionariesname:Dictionary = ["key":"value","key","value"]


Example :
var friendandage:Dictionary = ["parth":"20","hardik":"23","fevin":"22","vijay":"21"]

access dictionaries value by key
Syntax:

dictionariesname["key"]

Example:
friendandage["hardik"]

if you are add same value in dictionary following this syntax:

dictionariesname["key"] = "value"

Example:
friendandage["hiren"] = "25"

if you are update value in dictionary following this syntax:

dictionariesname["oldkey"] = "value"

Example:

friendandage["parth"] = "30"


If you are deleted a value in dictionary following this syntax:

dictionariesname["oldkey"] = nil

Example:

friendandage["fevin"] = nil

If you are print dictionary in reverse following this syntax:

dictionariesname.reverse()

your dictionary is print in reverse order 

If you count a value in dictionary in following this syntax:
friendandage.count

If you are remove all value in dictionary following this syntax:

friendandage.removeAll()

How to Create Array in swift language 

 The array is used for store multiple values. Array available any type of language.The array is store only values and array is accessed by id.Id is stat by 0,1,2,3,4...

 The array is two way to create .first way is an empty array and second array with an array literal.you are store multiple values.The array is most importation for the store .The array is very flexible. you can append array, remove array,  insert array etc.   watch  this video for more understanding.
Download     
empty array
var friend:Array = [String] ()

Creating an Array with an Array Literal
var myFriendArray:Array = ["parth","hardik","fevin","hiren"]

access array values by 0,1,2,3..

  myFriendArray[0]       

change values in the array

   myFriendArray[3] = "vijay"     

append array

myFriendArray.append("king")   

insert value in fixed id

myFriendArray.insert("sarag", atIndex: 2)

removeFirst() function only removes first value of array

myFriendArray.removeFirst()    

removeLast() function is remove last value of array

myFriendArray.removeLast()     

removeAtIndex() function is remove id 2 value of array

myFriendArray.removeAtIndex(2)

the reverse function is used to print the reverse value of the array

myFriendArray = myFriendArray.reverse()   

count a value in the array

myFriendArray.count   

remove all values

myFriendArray.removeAll()     

remove all values 

myFriendArray.removeAll(keepCapacity: false)

How to declare the variable in swift language

the variable is very importation in any type of language. Swift language is supported by the two type of variable var and let. Var is used to change the value  and let is use not change the value (let is constant variable). Every variable declared in two-way. watch  this video for more understanding.
  


Step - 1

 First open your Xcode

Step - 2

Select create a new Playground project
if don't know how to create playground visited this line 

Step - 3
write your code in the playground


syntax:-
  (var type) variablename = values

two way to create a var variables
   string
var name =  "parth" // first way
var myname:String = "parth" // second way


Integer
var integer = 100
var myinteger:Int = 100

Float
var float = 10.1
var myfloat:Float = 10.1

boolean
var bool = true
var mybool:Bool = true



let is use not change the value (let is constant variable).

same two way to create a let variables

string
let letname = "parth"  // first way
let myletname:String = "parth" // second way

Integer
let letinteger = 100
let myletinteger:Int = 100

Float
let letfloat = 10.1
let myletfloat:Float = 10.1
boolean
let letbool = true
let myletbool:Bool = true


how to append a variable in swift language

// string
var appendstring = "parth"
appendstring += "hardik"

var myappendstring:String = "parth"
myappendstring += "hardik"


// integer
var appendinteger = 100
appendinteger += 100 // append variable
appendinteger -= 10 //  remove value

var myappendinteger:Int = 100
myappendinteger += 100

// float
var appendfloat = 10.1
appendfloat += 10.1
appendfloat -= 5.5

var myappendfloat:Float = 10.1
myappendfloat += 10.1
myappendfloat -= 5.5

// boolean
var appendbool = true
 appendbool = false // your not use binary operator

var myappendbool:Bool = true
myappendbool = false // your not use binary operator

// let variable is not append and remove because let is constant (not change values)

let letappend = 100
letappend += 100  //ERROE
