如何检测字符串是否包含字符串数组（单词）的任何成员？
这是数组：
let str:String = "house near the beach"
let wordGroups:[String] = ["beach","waterfront","with a water view","near ocean","close to water"]
以下未编译
let match:Bool = wordGroups.contains(where: str.contains)
我在用String扩大：
extension String {
func contains(_ strings: [String]) -> Bool {
strings.contains { contains($0) }
}
}
使用案例：
let str = "house near the beach"
let wordGroups = ["beach","waterfront", "with a water view", "near ocean", "close to water"]
let haveWord = str.contains(wordGroups)
