Ios NSRegularExpression计算不正确

我有以下密码正则表达式，它在密码的在线regex测试仪上正确计算。123：

/(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)(?!^[\\W]*$)(^[a-zA-Z0-9\\W]).{7,}/

let password = "Password.123"

let regex = try! NSRegularExpression(pattern: "/(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)(?!^[\\W]*$)(^[a-zA-Z0-9\\W]).{7,}/", options: [])

let range = NSRange(location: 0, length: password.count)
print("Valid: \(regex.firstMatch(in: password, options: [], range: range) != nil)")

在swift中执行NSRegularExpression时，它的计算结果不正确，无法找到密码的匹配项。123：

/(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)(?!^[\\W]*$)(^[a-zA-Z0-9\\W]).{7,}/

let password = "Password.123"

let regex = try! NSRegularExpression(pattern: "/(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)(?!^[\\W]*$)(^[a-zA-Z0-9\\W]).{7,}/", options: [])

let range = NSRange(location: 0, length: password.count)
print("Valid: \(regex.firstMatch(in: password, options: [], range: range) != nil)")

这是假的，但应该是真的。我哪里出错了？

从字符串中删除

/

。即

let regex = try! NSRegularExpression(pattern: "(?!^[0-9]*$)(?!^[a-z]*$)(?!^[A-Z]*$)(?!^[\\W]*$)(^[a-zA-Z0-‌​9\\W]).{7,}", options: [])

您是否尝试过从字符串中删除

/

？也就是说，

让regex=try！NSRegularExpression（模式：（？！^[0-9]*$）（？！^[a-z]*$）（？！^[a-z]*$）（？！^[a-zA-Z0-9\\W]*$）（^[a-zA-Z0-9\\W]）。{7，}选项：[）

啊，谢谢，我会把它作为答案，以便您可以标记它。
