Swift 5 判断数组中是否包含字符串，忽略大小写

let list = ["kAshif", "1", "2"]
let list2 = ["3", "4"]
let word = "Kashif"

if list.contains(where: { $0.caseInsensitiveCompare(word) == .orderedSame }) {
    print("list contains kAshif is true")
}

if list2.contains(where: { $0.caseInsensitiveCompare(word) == .orderedSame}) {
    print("list2 contains kAshif is true")
}

// print > list contains kAshif is true
