How to get the first element from an array in Swift
In this post we will give you information about How to get the first element from an array in Swift. Hear we will give you detail about How to get the first element from an array in SwiftAnd how to use it also give you demo for it if it is necessary.
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 ?? 0print(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.
