swift 2.0 split keyword from a string swift 3.1 migration

Question

split() in swift 3 is deprecated. What will be alternate for below code:

var fullNameArr = split(str) {$0 == "@"}

Answer 1

let world = "Hello, world!".characters.suffix(6).dropLast()
String(world) // → "world"

Here split, which returns an array of subsequences, is also used for string processing. It’s defined like that:

extension Collection {
func split(maxSplits: Int = default,
    omittingEmptySubsequences: Bool = default,
    whereSeparator isSeparator: (Self.Iterator.Element) throws -> Bool) rethrows
    -> [AnySequence<Self.Iterator.Element>]
}

For example:

let commaSeparatedArray = "a,b,c".characters.split { $0 == "," }
commaSeparatedArray.map(String.init) // → ["a", "b", "c"]
