iOS Interview Coding Challenges

In this tutorial you will learn basic iOS coding challenges , According to my personal Experience I have shared the list of iOS Interview Coding Challenges for beginners.

Problem1 : Find the total numbers of character in given sentence.“I love Swift Language.”

Answer:

let sentence = "I love Swift Language"
print(sentence.count) 

Problem 2 : Check the number Even or odd

Answer:

func checkEvenOdd()
{
   var num = 54
   guard  num % 2 ==  0 else 
     {
       print("Odd")
       return
     }
     print("Even")
}
checkEvenOdd()

Problem 3: Find the factorial of a Number

Answer:

func factorial(num : Int ) -> Int
{
    if num == 0
    {
     return 1
    }
    else 
    {
     return num * factorial(num: num - 1)
    }
}

Problem 4: Calculate Area and Volume

Answer:

class Hall {
var length = 0.0
var height  = 0.0
var breadth = 0.0
func calculateArea()
{
   let result1 = length * breadth
   print( result1)
}
func calculateVolume()
 {
    let result2 = length * breadth * height
    print(result2)
 }
}
var hall1 = Hall()
hall1.length = 3
hall1.breadth = 5
hall1.height = 4
hall1.calculateArea()
hall1.calculateVolume()

Problem 5: Find Largest Number among three Numbers

Answer:

var a = 0
var b = 3
var c = 7
if a > b 
{
     if a > c {
         print("A is big")
      }
}
else if b > c {
     print( "B is big")
}
else {
print("C is big")
}

Problem 6: Merge given two sentence, “I love Programming.” and “I code in Swift language”

Answer:

Method — 1 : Using Append parameter:

var firstLine : String = "I love Programming"
var secondLine : String = "I code in Swift language"
firstLine.append(secondLine)
print(firstLine)

Method 2 : Using Operator

var firstLine : String = "I love Programming"
var secondLine : String = "I code in Swift language"
let result = firstLine + secondLine
print(result)

Problem 7: Add Two numbers Using Parameters and Return type

Answer:

func addTwoNumbers(no1 : Int, no2 : Int) -> Int
{
var total = no1 + no2
return total
}

I hope these iOS challenges are useful and will help you to get the best job.

Happy Coding 😁
