Returns a subsequence, up to the given maximum length, containing the final elements of the collection.
SDK
- Xcode 8.0+
Framework
- Swift Standard Library
Declaration
func suffix(_ maxLength: Int) -> Substring.UnicodeParameters
maxLengthThe maximum number of elements to return.
maxmust be greater than or equal to zero.Length
Return Value
A subsequence terminating at the end of the collection with at most max elements.
Discussion
If the maximum length exceeds the number of elements in the collection, the result contains the entire 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]"
Complexity: O(1) if the collection conforms to Random; otherwise, O(k), where k is equal to max.
