Accesses a contiguous subrange of the array’s elements.
- Xcode 9.3+
- Swift Standard Library
A range of integers. The bounds of the range must be valid indices of the array.
Array instance uses the same indices for the same elements as the original array. In particular, that slice, unlike an array, may have a nonzero
start and an
end that is not equal to
count. Always use the slice’s
end properties instead of assuming that its indices start or end at a particular value.
This example demonstrates getting a slice of an array of strings, finding the index of one of the strings in the slice, and then using that index in the original array.
