Search by regular pattern in iOS

Question

Trying to search bbcode-style tags with regular expression:

For example, I needed [user=1]John Dow[/user] with regular: [[user=[0-9]+].*?[/user]] But couldn't receive needed result.

Escape the opening square brackets `\[user=[0-9]+].*?\[/user]` — The fourth bird, Nov 27 '19 at 14:01
Would you like to use `[` as special for making character ranges or look for it explicitly? Both? How about escaping it in cases for literal "search for a ["? — Yunnosch, Nov 27 '19 at 14:01

Remove the outer pair of brackets and escape the literal brackets (unlike the range-of-characters brackets)

let pattern = "\\[user=[0-9]+\\].*?\\[/user\\]"
