EACodeScanner: Simplify Barcode and QR Code Scanning in Your SwiftUI iOS App

Introduction:

Barcode and QR code scanning have become essential features in many iOS applications. These technologies enable users to quickly access information, track products, and perform various tasks with ease. However, implementing code scanning functionality can be complex and time-consuming. That’s where EACodeScanner comes to the rescue. EACodeScanner is a versatile library that simplifies barcode and QR code scanning in iOS apps, providing a straightforward and customizable API. In this blog post, we will explore the features and benefits of EACodeScanner and see how it can streamline the process of integrating code scanning capabilities into your projects.

Features and Benefits:

1. Easy Integration: EACodeScanner makes it effortless to integrate code scanning into your iOS apps. With just a few lines of code, you can have a fully functional code scanner up and running. This saves you time and effort, allowing you to focus on other important aspects of your application.

2. Versatile Code Scanning: The library supports both barcode and QR code scanning. Whether you need to scan product barcodes, tickets, or any other type of code, EACodeScanner has you covered. It provides a robust scanning engine that can handle various types of codes with high accuracy.

3. Flexible Integration Options: EACodeScanner provides flexible integration options, allowing you to embed the scanner view wherever you need it in your app’s user interface. Whether it’s a dedicated scanning screen or an overlay on top of an existing view, you have full control over the placement and presentation of the scanner.

Installation:

To get started with EACodeScanner, follow these simple steps:

1. Open your Xcode project.
2. Navigate to the project settings and select your project.
3. Go to the “Swift Packages” tab.
4. Click on the “+” button to add a new package.
5. Enter the following URL: https://github.com/evangelistsw/EACodeScanner.git
6. Choose the version 1.0.0 of the library.
7. Select the appropriate targets for integration.
8. Let the Xcode handle the package resolution and integration.

Usage:

Once you have installed EACodeScanner, incorporating code scanning functionality into your SwiftUI app is a breeze. Let’s walk through a basic implementation:

Import the EACodeScanner module into your SwiftUI view file.

import EACodeScanner

CodeScanner(
    result: $scannedCode,
    isSessionStarted: $isSessionStarted,
    isCameraSupported: $isCameraSupported,
    hasCameraAccess: $hasCameraAccess
)
.metadataObjectTypes([.ean8, .ean13])
.onChange(of: scannedCode) { code in
     /* 
      Upon receiving the code, you can perform the necessary actions, 
      such as closing the CodeScanner or continuing with further scanning,
     depending on your specific requirements. 
      */
    print(code)
}        

Here we create an instance of EACodeScannerView, providing the required parameters for initialization. The parameters are

scannedCode: This is a binding string variable that captures the scanned code. Upon receiving the code, you can perform the necessary actions, such as closing the CodeScanner or continuing with further scanning, depending on your specific requirements.

isSessionStarted: This flag indicates whether the scanning session has started or not.

isCameraSupported: This flag determines if the device supports a camera. For example, the simulator doesn’t have a camera, so it will return false. You can use this flag to display appropriate messages to the user.

hasCameraAccess: This flag checks whether the user has granted camera access for barcode scanning.

In the metadataObjectTypes view modifier, When using the metadataObjectTypes view modifier, you can pass the desired metadata based on your requirements. For barcode scanning, use .ean8 and .ean13. For QR code scanning, use .qr.
