Swift Programming Examples

While Loop

swift

var index = 10

while index < 20 {
   print( "Value of index is \(index)")
   index = index + 1
}

for-in Loop

swift

var someInts:[Int] = [10, 20, 30]

for index in someInts {
   print( "Value of index is \(index)")
}

Switch Statement Program 2

swift

var index = 10

switch index {
   case 100 :
      print( "Value of index is 100")
      fallthrough
   case 10,15 :
      print( "Value of index is either 10 or 15")
      fallthrough
   case 5 :
      print( "Value of index is 5")
   default :
      print( "default case")
}

Switch Statement Program1

swift

var index = 10

switch index {
   case 100 :
      print( "Value of index is 100")
   case 10,15 :
      print( "Value of index is either 10 or 15")
   case 5 :
      print( "Value of index is 5")
   default :
      print( "default case")
}

Nested If Statements

swift

var varA:Int = 100;
var varB:Int = 200;

/* Check the boolean condition using if statement */
if varA == 100 {
   /* If condition is true then print the following */
   print("First condition is satisfied");

   if varB == 200 {
      /* If condition is true then print the following */
      print("Second condition is also satisfied");
   }
}

print("Value of variable varA is \(varA)");
print("Value of variable varB is \(varB)");

Ifelse ifelse Statement

swift

var varA:Int = 100;

/* Check the boolean condition using if statement */
if varA == 20 {
   /* If condition is true then print the following */
   print("varA is equal to than 20");

} else if varA == 50 {
   /* If condition is true then print the following */
   print("varA is equal to than 50");

} else {
   /* If condition is false then print the following */
   print("None of the values is matching");
}

print("Value of variable varA is \(varA)");

Swift If Else Statement

swift

var varA:Int = 100;

/* Check the boolean condition using if statement */
if varA < 20 {
   /* If condition is true then print the following */
   print("varA is less than 20");

} else {
   /* If condition is false then print the following */
   print("varA is not less than 20");
}

print("Value of variable varA is \(varA)");

Swift If Statement

swift

var varA:Int = 10;

/* Check the boolean condition using if statement */
if varA < 20 {
   /* If condition is true then print the following */
   print("varA is less than 20");
}

print("Value of variable varA is \(varA)");

String Literals

swift

let stringL = "Hello\tWorld\n\nHello\'Swift 4\'"
print(stringL)

Printing Constants

swift

let constA = "Godzilla"
let constB = 1000.00

print("Value of \(constA) is more than \(constB) millions")
