A Swift library for defining strong password generator rules.
This functionality is discussed in the NSHipster article Password Rules / UITextInputPasswordRules.
- Swift 4.0+
Add the PasswordRules package to your target dependencies in Package.swift:
import PackageDescription
let package = Package(
name: "YourProject",
dependencies: [
.package(
url: "https://github.com/NSHipster/PasswordRules",
from: "1.0.0"
),
]
)Then run the swift build command to build your project.
To use PasswordRules in your Xcode project using Carthage,
specify it in Cartfile:
github "NSHipster/PasswordRules" ~> 1.0.0
Then run the carthage update command to build the framework,
and drag the built PasswordRules.framework into your Xcode project.
Define an array of PasswordRules cases
and use the descriptor(for:) method to create a string representation:
import PasswordRules
let rules: [PasswordRule] = [ .required(.upper),
.required(.lower),
.required(.special),
.minLength(20) ]
let descriptor = PasswordRule.descriptor(for: rules)
// "required: upper; required: lower; required: special; minlength: 20;"Initialize a UITextInputPasswordRules object using the descriptor
and pass that to the passwordRules property of a secure text field:
import UIKit
guard #available(iOS 12, *) else {
fatalError()
}
self.passwordTextField.passwordRules =
UITextInputPasswordRules(descriptor: descriptor)MIT
