如何检查字符串值是否是数组或不使用SWIFT

Question

我尝试这样做：

var array = ["led","zepp","jimmy","page"] 

if array.contains("jimmy") { // error : [String] does not have a member named 'contains' . 
    print("yes") 
} 

什么是对[String]类型数组的语法？

依赖于迅速的版本...在1.2：

var array = ["led","zepp","jimmy","page"] 
    if find(array, "jimmy") != nil { 
     println("yay") 
    }

var array = ["led","zepp","jimmy","page"] 
    if array.indexOf("jimmy") != nil { 
     print("yay") 
    }
