The swapAt() method swaps two elements at the specified indices of the array.
Example
swapAt() Syntax
The syntax of the array swapAt() method is:
array.swapAt(index1: Int, index2: Int)
Here, array is an object of the Array class.
swapAt() Parameters
The swapAt() method takes two parameters:
- index1 - index of the first element to swap
- index2 - index of the second element to swap
swapAt() Return Value

Example 1: Swift Array swapAt()
Output
["Swift", "Java", "C"] [35, 21, 12]
Here,
- For the languages array, we have swapped the elements of index 1 and index 2.
- Similarly, for the priceList array, we have swapped the elements of index 0 and index 2.
