I have a weird behavior for my with regex so I hope someone can explain it to me:

let passwordTest = NSPredicate(format: "SELF MATCHES %@", "^(?=.*[A-Z]).(?=.*[0-9]).(?=.*[a-z]).{8,}$")

I want my password to be at least 8 characters. But with the code above it is only allowing passwords more than 8 characters. I used to thought that {8,} means >= and not >.

I know I can just change it to {9,} but I want to make sure that my logic is right, because if searching for this topic I always see that it means >=. So if anyone could just clarify that I'd be grateful :)

There are extraneous dots between lookaheads, remove them. The only consuming pattern should be `.{8,}` – Wiktor Stribiżew Apr 02 '20 at 12:32
that was the problem, thanks:) – Chris Apr 02 '20 at 12:41
