Instance SubscriptSwift


    Accesses a contiguous subrange of the array’s elements.

    subscript(bounds: Range<Int>) -> ArraySlice<Element> { get set }



    A range of integers. The bounds of the range must be valid indices of the array.


    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]
    // Prints "["Channing", "Douglas", "Evarts"]"
    let i = streetsSlice.firstIndex(of: "Evarts")    // 4
    // Prints "Evarts"
