Instance Methodswift 6.0.1Swift
suffix(_:)
Returns a subsequence, up to the given maximum length, containing the final elements of the collection.
func suffix(_ maxLength: Int) -> Self.SubSequence Parameters
- maxLength
The maximum number of elements to return. The value of
maxLengthmust be greater than or equal to zero.
Returns
A subsequence terminating at the end of the collection with at most maxLength elements.
If the maximum length exceeds the number of elements in the collection, the result contains all the elements in the collection.
let numbers = [1, 2, 3, 4, 5]
print(numbers.suffix(2))
// Prints "[4, 5]"
print(numbers.suffix(10))
// Prints "[1, 2, 3, 4, 5]"Other members in extension
