var hoge:[(id:Int, name:String)] = [(1, "name1"), (2, "name2"), (3, "name3"), (4, "name4"), (5, "name5")]
extension MutableCollectionType where Index == Int {
mutating func shuffle() {
for i in 0 ..< count - 1 {
let j = Int(arc4random_uniform(UInt32(count - i - 1))) + i + 1
swap(&self[i], &self[j])
}
}
}
hoge.shuffle()
print(hoge)
