How to get the first element from an array in Swift

Learn, how to get the first element of a given array in Swift.

Consider, we have a following prices array:

var prices = [34, 23, 12, 44, 52]

To access the first element (34) from an above array, we can use the subscript syntax [ ] by passing its index.

Example:

var prices = [34, 23, 12, 44, 52]

let firstElement = prices[0]

print(firstElement) // 34

Note: In Swift arrays are zero-indexed, so the first element index is 0 .

Similarly, we can also use the first instance property like this.

var prices = [34, 23, 12, 44, 52]

let firstElement = prices.first ?? 0

print(firstElement) // 34

The question marks ?? in the above code returns 0 if the prices array is empty or nil; otherwise it returns the first element in an array.
