Most modern smartphones are capable of writing to and reading from NFC tags. If let url = record.Near Field Communication (NFC) is a short-range protocol of communication between devices, typically between an NFC tag and a scanner. This function is only available from iOS 13 we need to continue on the main thread if we plan to update the UI Remember: this delegate function runs on a background thread, Import CoreNFC and Create Reader Session import CoreNFCĬlass ScannerViewController: UIViewController Setting the value as something which explains the purpose of accessing NFC is recommended, and might make the App Store review process go smoother. In the past the value for this key used to be displayed to the user when they begin scanning in the original version of the framework, but this has changed since then and the message shown to the user can now be customized when starting the scan instead. Navigate to your ist file and add a new line for the key named Privacy - NFC Scan Usage Description. This will enable your app to access NFC on your user’s devices.Īfter adding the NFC capability to your project and building, it should automatically enable the capability for your App ID, but if there are any issues you can manually enable the “NFC Tag Reading” service on the Apple Developer Console for your App ID. From the list that appears, choose “Near Field Communication Tag Reading”. Choose “Signing and Capabilities” (1), and press the “+” button (2) at the top next to "All", “Debug” and “Release”. The first thing you should do is to navigate to your project file and select the target you’re adding NFC to. The implementation might be somewhat different for SwiftUI or other versions of Swift or Xcode.Īpps that use NFC must add the capability in their project, otherwise you won’t be able to access the framework. Note: These instructions were written for apps using UIKit, Swift 5, and Xcode 13.3. Extract NFC Data from messages received in the delegate.Conform to NFCNDEFReaderSessionDelegate and add the delegate functions that you need.Import the CoreNFC framework and create an NFCNDEFReaderSession.Add the NFC capability to your project and App ID.The basic steps needed to set up CoreNFC are pretty straightforward: Let’s explore how to incorporate CoreNFC into an iOS application using Swift. CoreNFC in iOSĪpple has managed to create a simple, easy to use framework which allows developers to interact with NFC capable devices with little code required. After the release of iOS 11 in 2017 developers could finally take advantage of the technology by using Apple’s CoreNFC framework. Initially, NFC was restricted to only Apple Pay and third party developers had no access to the actual NFC capabilities to include in their own apps. With the introduction of Apple Pay on iPhone 6 and 6+, Apple felt that it finally had a compelling use-case to get people interested in using NFC in their daily lives. NFC itself has been around since the early 2000s, but it wasn’t until 2014 when iPhone users were first given NFC capabilities, lagging slightly behind Android users who had already been enjoying the feature for a few years. Societies that were once run on cash transactions have slowly shifted away from physical payments and replaced them with NFC taps and QR code scans. NFC capable devices and credit cards have also become more and more common in the last decade or so as a result of business owners bringing their businesses into the age of contactless payments. NFC is finding its way into the technology we use in our daily lives and connects physical items to the digital world such as Apple’s Air Tags, and also helps you to quickly scan your train pass at the train stations here in Tokyo. Near Field Communication, commonly referred to as NFC, is a short-range wireless communication technology available on more than two billion devices around the world which enables you to do things like process digital payments, easily transfer data, and even unlock your front door. First, I’ll give some background on what NFC is, I’ll explain the steps involved for using NFC in iOS development, and then we’ll go through the code. In this article I’ll briefly introduce how to implement NFC on iOS. This Day 5 post of Merpay Tech Openness Month 2022 is brought to you by Kris from the Merpay iOS team.
