Is there any way using swift 3 we can match a string with Multiple regular expression patterns. In Java, we usually pass them as below
[a-zA-Z]{3}|^[^\\d].*|([\\w&&[^b]])*
Is there any similar way we can do it using Swift.

There's not Regex in Swift itself (yet). You should use Foundation's [NSRegularExpression](https://developer.apple.com/reference/foundation/nsregularexpression). – Eric Aya Feb 28 '17 at 15:45

Are you asking if `|` is supported by NSRegularExpression? Yes, it is. – Wiktor Stribiżew Feb 28 '17 at 16:03

@WiktorStribiżew I didn't try that..I don't know where I am going wrong. Do we have any func() which actually matches multiple NSRegularExpression – user1642224 Feb 28 '17 at 16:08

The `[\\w&&[^b]]` is most probably the culprit. In ICU, it is set as `[\\w--b]` (or `[\\w--[b]]`). As for multiple matches, no, you need to implement it. There are such questions on SO.
