swift 2.0从一个字符串swift中拆分关键字3.1迁移

Question

在swift 3中的split()已被弃用。会有什么替代为如下代码：

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

Answer 1

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

这里分裂，它返回子序列的阵列，也用于字符串处理。它的定义那样：

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

对于例如：

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