CODE BREAKDOWN

//1 -> UIKIT being imported from the Xcode library for the essentials in the code.

//2 -> A New class called CLASS VIEWCONTROLER is created which is a super class of UIViewcontroller.
NOTE -  Any code in the format of [ Class superclass : subclass {.....} ] refers to a
super class which has a subclass nested in it.


//3 -> An array is declared using "LET" key word, the array contains all the dice names.


//4 -> IBOutlets being linked to the viecontroller where , the first outlet is linked to the first image (dice1),  the second is linked to the second image (dice2)


//5 -> Two variables is created named randomDIceIndex1 and randomDIceIndex2 which are initially set to a value '0'


//6 -> UpdateDiceImage is a function which is written to update random dice images when roll button is pressed , that function is being called here


//7 -> IBAction function in which triggers after roll button is pressed hence the updateDiceImages function is being called inside


//8 & //9 -> The function updateDiceImages which is used a couple of times is written, where randomDiceIndex1 and randomDiceIndex2 which are set to a default value of '0' are allowed here to come up with any random number between 0-5 using " Int.random(in: 0 ... 5) " key word. The array which is mentioned above which has all the dice are being randomly called here

**there are 6 elements in the array, where as we are calling until 5 here**
this is because the array is counted from '0' ,  which is 0 to 1 to 2 to 3... to 5.


//10 -> "diceImageView1.image = UIImage(named: diceArray[randomDiceIndex1])" This enables the dice images to change randomly with the number in the above line.
