# subscript(_:) Accesses a contiguous subrange of the array’s elements. ``` subscript(bounds: Range) -> ArraySlice { get set } ``` ## Parameters `bounds` A range of integers. The bounds of the range must be valid indices of the array. ## Overview The returned `ArraySlice` instance uses the same indices for the same elements as the original array. In particular, that slice, unlike an array, may have a nonzero `startIndex` and an `endIndex` that is not equal to `count`. Always use the slice’s `startIndex` and `endIndex` 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. ``` let streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"] let streetsSlice = streets[2 ..< streets.endIndex] print(streetsSlice) // Prints "["Channing", "Douglas", "Evarts"]" let i = streetsSlice.firstIndex(of: "Evarts") // 4 print(streets[i!]) // Prints "Evarts" ``` --- Copyright © 2026 Apple Inc.
