How to Convert Integer to String in Swift


How to Convert Integer to String in Swift ?

Answer

In Swift, you can convert an integer to a string using the String() initializer or string interpolation.



✐ Examples

1 Convert Integer to String using String() Initializer

In this example,

  1. We declare an integer constant named num and assign it a value of 42.
  2. We then initialize a string strNum using the String() initializer with the integer num.
  3. The String() initializer converts the integer to its string representation.
  4. Finally, we print the string representation of the integer.

Swift Program

// Convert Integer to String using String() Initializer
let num = 42
let strNum = String(num)
print("String representation of integer: \(strNum)")

Output

String representation of integer: 42

2 Convert Negative Integer to String using String Interpolation

In this example,

  1. We declare a negative integer constant named negativeNum with a value of -10.
  2. We then use string interpolation to convert the negative integer negativeNum to a string and store the result in the constant strNegativeNum.
  3. String interpolation automatically converts the integer to its string representation.
  4. Finally, we print the string representation of the negative integer.

Swift Program

// Convert Negative Integer to String using String Interpolation
let negativeNum = -10
let strNegativeNum = "String representation of negative integer: \(negativeNum)"
print(strNegativeNum)

Output

String representation of negative integer: -10
