Introduction

Validation Components extends the ValidationToolkit framework by offering a collection of common validation predicates that most of the projects can benefit of.

Requirements

• iOS 8.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+
• Xcode 8.1+
• Swift 3.0+

Installation

Please note that ValidationComponents requires ValidationToolkit.

Carthage

You can use Carthage to install ValidationComponents by adding it to your Cartfile:

github "nsagora/validation-components"

Run carthage update to build the framework and drag the built ValidationComponents.framework into your Xcode project.

Setting up Carthage

Carthage is a decentralised dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

CocoaPods

You can use CocoaPods to install ValidationComponents by adding it to your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target 'YOUR_TARGET_NAME' do
	pod 'ValidationComponents'
end

Then, run the following command:

$ pod install

Note that this requires CocoaPods version 1.0.0, and your iOS deployment target to be at least 8.0.

Setting up CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

Swift Package Manager

You can use the Swift Package Manager to install ValidationComponents by adding it to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .Package(url: "https://github.com/nsagora/validation-components", majorVersion: 1),
    ]
)

Note that the Swift Package Manager is still in early design and development, for more information checkout its GitHub Page.

Manually

To use this library in your project manually you may:

1. for Projects, just drag the Sources folder into the project tree
2. for Workspaces, include the whole ValidationComponents.xcodeproj

Usage example

For a comprehensive list of examples try the ValidationComponents.playground:

1. Download the repository locally on your machine
2. Run carthage update to build the required version of ValidationToolkit

Setting up Carthage

Carthage is a decentralised dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

3. Open ValidationComponents.workspace
4. Build ValidationComponents iOS target
5. Select the ValidationComponents playgrounds from the Project navigator.

Email Predicate

Use a EmailPredicate to evaluate if a given email address is syntactically valid.

import ValidationComponents

let predicate = EmailPredicate()
predicate.evaluate(with: "hello@") // returns false
predicate.evaluate(with: "hello@nsagora.com") // returns true
predicate.evaluate(with: "héllo@nsagora.com") // returns true

URL Predicate

Use a URLPredicate to evaluate if a given URL is syntactically valid.

import ValidationComponents

let predicate = URLPredicate()
predicate.evaluate(with: "http://www.url.com") // returns true
predicate.evaluate(with: "http:\\www.url.com") // returns false

Pair Matching Predicate

Use a PairMatchingPredicate to evaluate if a given pair of values match.

import ValidationComponents

let predicate = PairMatchingPredicate()
predicate.evaluate(with: ("swift", "swift")) // returns true
predicate.evaluate(with: ("swift", "obj-c")) // returns false
