### Basic Validation

.rule { $0.count >= 3 }
validator.check("abc") // true
validator.check("") // false let hasDigit = Valid8().rule { $0.contains { $0.isNumber } }
let hasUpper = Valid8().rule { $0.range(of: "[A-Z]", options: .regularExpression) != nil }
let strongValidator = hasDigit && hasUpper
strongValidator.check("Password123") // true
```
## Password Validation
Use the built-in `checkPasswordValidity` function:
```swift
let isValid = Valid8().checkPasswordValidity("Aa1@#ValidPass")Or compute strength:
let strength = Valid8().checkPasswordStrength("Aa1@#ValidPass") // Score out of 5Tests are written using Apple’s new swift-testing framework.
