How do I access the not-the-first elements of an array in Swift?


Swift's Array has a first function which returns the first element of the array (or nil if the array is empty.)

Is there a built-in function that will return the remainder of the array without the first element?


Solution

  • There is one that might help you get what you are looking for:

    func dropFirst<Seq : Sliceable>(s: Seq) -> Seq.SubSlice
    

    Use like this:

    let a = [1, 2, 3, 4, 5, 6, 7, 18, 9, 10]
    
    let b = dropFirst(a) // [2, 3, 4, 5, 6, 7, 18, 9, 10]
