Hello everyone,
first let me say a few words about myself. I am an IT student and I want to learn and develop some applications in Swift. Now I am working on one application and I need a barcode scanner to complete it. So I need help from someone who can help me with a simple barcode scanner. My idea is that the barcode will be on one screen and they have to read the code and write it to a variable. That's my idea. I will appreciate the full code or help. thank you for answer

Hi everyone, do you know when real-time subtitles for Italian language calls will be implemented in iPhone?

I have a live text implementation on the following LiveTextImageView. However, after the view loads and the analyze code is run, none of the delegate methods fire when I interact with the Live View. Selecting text does not fire the textSelectionDidChange method, nor does highlightSelectedItemsDidChange fire when the live text button in the bottom right is pressed. I tried a few different implementations, including an approach where the delegate was defined on a separate class. I am running this on a iPhone 12 Pro I recently updated to 17.0.3.
My goal is to be able to provide additional options to the user beyond the default live-text overlay options, after identifying when they have finished selecting text.
//
// LiveTextImageView.swift
//
import UIKit
import SwiftUI
import VisionKit
class ImageAnalyzerWrapper {
static let shared = ImageAnalyzer()
private init() { }
}
struct LiveTextImageViewRepresentable: UIViewRepresentable {
var image: UIImage
func makeUIView(context: Context) -> LiveTextImageView {
return LiveTextImageView(image: image)
}
func updateUIView(_ uiView: LiveTextImageView, context: Context) { }
}
class LiveTextImageView: UIImageView, ImageAnalysisInteractionDelegate, UIGestureRecognizerDelegate {
var capturedSelectedText: String?
let analyzer = ImageAnalyzerWrapper.shared
let interaction = ImageAnalysisInteraction()
init(image: UIImage) {
super.init(frame: .zero)
self.image = image
let photoWrapper = PhotoWrapper(rawPhoto: image)
let resizedPhoto = photoWrapper.viewportWidthCroppedPhoto(padding: 40)
self.image = resizedPhoto
self.contentMode = .scaleAspectFit
self.addInteraction(interaction)
interaction.preferredInteractionTypes = []
interaction.analysis = nil
analyzeImage()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func analyzeImage() {
if let image = self.image {
Task {
let configuration = ImageAnalyzer.Configuration([.text])
do {
let analysis = try await analyzer.analyze(image, configuration: configuration)
self.addInteraction(interaction)
interaction.delegate = self
interaction.analysis = analysis
interaction.preferredInteractionTypes = .textSelection
}
catch {
print("Error in live image handling")
}
}
}
}
func interaction(
_ interaction: ImageAnalysisInteraction,
highlightSelectedItemsDidChange highlightSelectedItems: Bool) async {
print("Highlighted items changed")
}
func interaction(_ interaction: ImageAnalysisInteraction, shouldBeginAt point: CGPoint, for interactionType: ImageAnalysisInteraction.InteractionTypes) async -> Bool {
return interaction.hasInteractiveItem(at: point) || interaction.hasActiveTextSelection
}
func textSelectionDidChange(_ interaction: ImageAnalysisInteraction) async {
print("Changed!")
if #available(iOS 17.0, *) {
capturedSelectedText = interaction.text
print(capturedSelectedText ?? "")
}
}

We are using URL encoded in QR code to open our web application. When user scans QR using the default Camera app on iPhone, upon clicking the link iOS opens the webpage on safari browser. Our URL looks like this "https://abc.com?qrdata=1", "https://abc.com?qrdata=2", "https://abc.com?qrdata=3".
The URL query parameter(qrdata) differs for different process in the web app. So when so each QR code has same domain but different query parameters.
If the user scans QR for https://abc.com?qrdata=1, the web page is opened on safari without any issue. If user scansQR for https://abc.com?qrdata=2 after the first QR code then for some reason on first attempt Safari is loading the previously scanned URL, in this case https://abc.com?qrdata=1. The change in query params is not received correctly by Safari. If we scan the new QR code twice then works on 2nd attempt to scan the QR.
I can see from the history that the URL scanned is not the right url
This is issue only on Safari iOS devices, on anyother browser works as expected.

I was switching the Detector scanner from QR to Rectangle type of detection but on Rectangle type of detection I cannot take the feature.messageString out of CIRectangleFeature, while on CIQRCodeFeature it works. Only what I had changed was ofType: CIDetectorTypeQRCode into CIDetectorTypeRectangle and features as? [CIQRCodeFeature] into features as? [CIRectangleFeature]
here is the code
func processQRCodeImage(_ image: UIImage) {
var qrCodeLink = ""
let detector: CIDetector = CIDetector(ofType: CIDetectorTypeRectangle, context: nil, options: [CIDetectorAccuracy: CIDetectorAccuracyHigh])!
let ciImage: CIImage = CIImage(image: image)!
let features = detector.features(in: ciImage)
if let features = features as? [CIRectangleFeature] {
for feature in features {
qrCodeLink += feature.messageString! // Value of type 'CIRectangleFeature' has no member 'messageString' COMPILE ERROR
}
}
if qrCodeLink.isEmpty {
failedQRCoderead()
} else {
found(code: qrCodeLink)
onBackPressed?()
}
}

After loading iOS 17 on my iPhone 13 pro max it won't send the messages I type on my phone to iPad or Mac computers. I have restarted all iMessage settings several times checked message forwarding setting all are in order. I also checked the Apple ID it is the same on all devices. Any suggestions would be appreciated to fix the problem thanks.

Hello there! Really excited about this year's additions to ImageAnalysisInteraction, especially the selectedText. Thank you!
My question is if there's a way to have multiple interactions for a given image analysis. For example, instead of being able to make just one text selection, I would like to support multiple.
In theory, I know multiple UIInteraction-conforming objects can be added to any view but I'm unsure if this is possible with ImageAnalysisInteraction.
I'm willing to create a custom UIInteraction, if you see a potential way forward there (would love to hear any ideas!).
Side question/feature request: UITextSelectionDisplayInteraction, which I assume ImageAnalysisInteraction might be using internally, allows handleViews customizations and others. I would be super useful if that was exposed through ImageAnalysisInteraction as well!
Looking forward to hearing your ideas. TIA!
MORADENS.
