UI2code: How to Fine-tune Background and Foreground Analysis

After finishing the Mastermind project, which was the most difficult project so far, I moved to the Files and Serialization lesson in The Odin Project curriculum. I stumbled upon a lot of long articles full of technical language that for me, non-English native speaker were quite difficult to understand. Especially after coming back from my 9-5. When I was reading the last one, many things clicked and I thought it all could have been explained in a little easier way. I came up with an idea of how to make it in 6 simple steps and the results are below. This is a nice funky graph for you to visualize it: STEPS 1 - 2 Let’s start from the input. When you are typing something, input (IO) is taken from your keyboard and sent to TTY virtual device. TTY in Linux is the interface that handles input/output. STEP 3 The input is then passed to the TTY session (the terminal interface you interact with). STEP 4 From there, the TTY virtual device forwards it to the line discipline inside the kernel. Line discipline is the place where magic happens. For example, pressing BACKSPACE will clear the last character we typed in or process special keys, signals, and interpret commands. STEP 5 After processing, the line discipline sends the input to the foreground process (like a shell) via STDIN. STEP 6 When the process generates output, it then sends it to STDOUT or STDERR if it’s an error, which goes back through the TTY virtual device and then displays on the TTY session again. Final thoughts Don’t you think these processes are really interesting? Since I started learning how to code I was always curious about how everything works under the hood. What happens when you press some buttons, what kind of signals are sent, where they are going, and so on. Maybe in the future, I will make a similar graph to visualize something else. We will see what I will get stuck at soon. If you have more questions, drop a comment below! I’d love to hear what topics you’re struggling with or find intriguing. Your feedback helps me decide what to break down next. Happy learning!

Day 23: AVKit Integration – Playing Videos and Media in SwiftUI 🎬 Today, we’ll explore how to integrate AVKit into your SwiftUI project. AVKit is the framework that lets you play videos and audio seamlessly with built-in controls. Comments for Customization: player.play(): This starts video playback.
cornerRadius(10): This rounds the corners of the video view, making it visually appealing.
frame(height: 300): The video player is confined to a specific height, ensuring a clean layout. Here's the code for the implementation shown: import AVKit

ARKit & LiDAR: Building Point Clouds in Swift (part 2)

Day 21: Custom Toggle Button, anyone? ⚙️ Today, we’re going to create a custom toggle button in SwiftUI. Implementing a Custom Toggle Button In this example, we’ll create a visually appealing custom toggle button that switches between on and off states. Code Example Here’s how you can implement a custom toggle button in SwiftUI: import SwiftUI

struct CustomToggle: View {
    @Binding var isOn: Bool // Binding variable for toggle state

        var body: some View {
            HStack {
                Text("Toggle Setting")
                    .foregroundColor(.primary) // Text color
                Spacer()
                // Custom square toggle design
                RoundedRectangle(cornerRadius: 5) // Rounded corners
                    .fill(isOn ? Color.blue : Color.gray) // Toggle color based on state
                    .frame(width: 60, height: 30) // Toggle size
                    .overlay(
                        Rectangle() // Square knob design
                            .fill(Color.white)
                            .frame(width: 26, height: 26)
                            .offset(x: isOn ? 15 : -15) // Move the square based on state
                            .animation(.easeInOut(duration: 0.2), value: isOn) // Animation for smooth transition
                    )
                    .onTapGesture {
                        isOn.toggle() // Toggle the state on tap
                    }
            }
            .padding() // Padding for the entire toggle
        }
    }

struct ContentView: View {
    @State private var isToggleOn = false // State to manage toggle status

    var body: some View {
        VStack {
            CustomToggle(isOn: $isToggleOn) // Custom toggle instance
            Text(isToggleOn ? "Setting is ON" : "Setting is OFF") // Display current state
                .padding()
        }
        .padding()
    }
}

@main
struct CustomToggleApp: App {
    var body: some Scene {

Happy Coding! 🎈 Day 21: Custom Toggle Button, anyone? ⚙️ Day 21: Custom Toggle Button, anyone? ⚙️ Today, we’re going to create a custom toggle button in SwiftUI. custom toggle button Implementing a Custom Toggle Button In this example, we’ll create a visually appealing custom toggle button that switches between on and off states. Code Example Here’s how you can implement a custom toggle button in SwiftUI: import SwiftUI

struct CustomToggle: View {
    @Binding var isOn: Bool // Binding variable for toggle state

        var body: some View {
            HStack {

                    .foregroundColor(.primary) // Text color
                Spacer()
                // Custom square toggle design
                RoundedRectangle(cornerRadius: 5) // Rounded corners
                    .fill(isOn ? Color.blue : Color.gray) // Toggle color based on state
                    .frame(width: 60, height: 30) // Toggle size

How to Create a Custom Toggle Button in iOS 18 - #30DaysOfSwift

In the ever-evolving landscape of mobile app development, the ability to process and analyse images in real time has become increasingly important. If you are a Flutter developer you must have relied on the google ml kit for flutter to bring powerful machine learning capabilities to their apps. Today, I’m excited to announce a significant enhancement to this package with the addition of subject segmentation. Subject segmentation allows developers to easily separate multiple subjects from the background in a picture, enabling use cases such as sticker creation, background swap, or adding cool effects to subjects. Subject refers to the primary people, animals, or objects that appear in the foreground of an image. If you have two subjects very close or touching each other, they are considered a single subject. The subject segmentation processes an input image and produces an output mask or bitmap for the foreground. If you are new to theGoogle ML Kit Flutter, it is a set of Flutter plugins that enable Flutter apps to use Google’s standalone ML Kit, making it easy to use these powerful ML features in Flutter apps. Before this addition, google_ml_kit for Flutter already offered a range of capabilities including text recognition, face detection, pose estimation and more. These features have enabled developers to create sophisticated apps with minimal effort in implementing complex ML algorithms. Using Subject Segmentation on your Flutter app To use the new subject segmentation on your app, you can follow these simple steps Firstly, what are the requirements? iOS: This feature is still in Beta, and it is only available for Android. Stay tuned for updates on Google’s website and request the feature here Android minSdkVersion: 24
targetSdkVersion: 33
complieSdkVersion: 34 You can configure your app to automatically download the model to the device after your app is installed from the Play Store. To do so, add the following declaration to your app’s AndroidManifest.xml file: <application ...>
      ...
      <meta-data
          android:name="com.google.mlkit.vision.DEPENDENCIES"
          android:value="subject_segment" >
      
</application> Secondly, update your pubspec.yaml file by adding the google_ml_kit_subject_segmentation and running an implicit flutter pub get dependencies:
  google_mlkit_subject_segmentation: ^0.0.1 Or run this command on your terminal flutter pub add google_mlkit_subject_segmentation Now in our Dart code, you can use: import 'package:google_mlkit_subject_segmentation/google_mlkit_subject_segmentation.dart'; Usage Create an instance of InputImage with either of these three ways: From path: final inputImage = InputImage.fromFilePath(filePath); From file: final inputImage = InputImage.fromFile(file); From bytes: final inputImage = InputImage.fromBytes(bytes: bytes, metadata: metadata); Create an instance of SubjectSegmenter final options = SubjectSegmenterOptions(
    enableForegroundConfidenceMask: true,
    enableForegroundBitmap: false,
    enableMultipleSubjects: SubjectResultOptions(
      enableConfidenceMask: false,
      enableSubjectBitmap: false,
    ),
  );

final segmenter = SubjectSegmenter(options: options); Let’s discuss the options. We have four of them. Don’t worry; I will explain them one after the other. Foreground confidence mask The foreground confidence mask lets you distinguish the foreground subject from the background. To enable the confidence mask, you have to pass true to enableForegroundConfidenceMask enableForegroundConfidenceMask: true Foreground bitmap Similarly, you can also get a bitmap of the foreground subject, To enable that you have to passtrue to enableForegroundBitmap enableForegroundBitmap: true, Multi-subject confidence mask As for the foreground options, you can use the SubjectResultOptions to enable the confidence mask for each foreground subject as follows: SubjectResultOptions(
      enableConfidenceMask: true,
      enableSubjectBitmap: false,
    ) Multi-subject bitmap Similarly, you can enable the bitmap for each subject: SubjectResultOptions(
      enableConfidenceMask: false,
      enableSubjectBitmap: true,
    ) Process image final result = await segmenter.processImage(inputImage); Release resources with close segmenter.close(); https://vimeo.com/1019321142 In the example above, I used the Foreground Bitmap you can also check the source code below https://github.com/bensonarafat/subject_segmentation?source=post_page-----e1a954e7ec09-------------------------------- I can’t wait to see what you all build with this.

Elevate Your Flutter App: A Guide to Subject Segmentation Using Google ML Kit

Day 14: Enhancing Interactions with Context ⚙️ Welcome back to the #30DaysOfSwift series! Today, let's look at Context Menus. A powerful way to offer additional actions when users long-press or right-click on UI elements. By integrating context menus into your SwiftUI app, you can create a smooth, intuitive experience for users when interacting with different elements. What are Context Menus? Context Menus provide additional actions that a user can perform on an element. They are revealed via a long press or right-click, making it easy for users to access additional options without cluttering the UI. Code Example: Context Menus in Action struct ContextMenuExample: View {
    @State private var favorite: Bool = false

    var body: some View {
        VStack {
            HStack {
                Text("Long-press me!")
                    .font(.title2)
                    .padding()
                Spacer()
                if favorite {
                    Image(systemName: "heart.fill")
                        .foregroundColor(.red) // Customization: Heart icon if marked as favorite
                }
            }
            .frame(maxWidth: .infinity)
            .padding()
            .background(Color.blue.opacity(0.2)) // Custom background color
            .cornerRadius(10) // Rounded corners for aesthetic touch
            .contextMenu { // Adding the context menu
                Button(action: {
                    favorite.toggle()
                }) {
                    Label("Favorite", systemImage: favorite ? "heart.fill" : "heart")
                }

                Button(action: {

                }) {
                    Label("Share", systemImage: "square.and.arrow.up")
                }

                Button(action: {
                    print("Deleted!")
                }) {

Context Menus in iOS 18 - #30DaysOfSwift

Day 12: Mastering Gestures – Swipe, Tap, and Pinch ✋ In my twelfth post of the #30DaysOfSwift series, let me tell you about the Gesture Recognizers in SwiftUI. They are swipe, tap, and pinch that can bring an intuitive feel to your app, making it engaging for your users. Steps to Add Gesture Recognizers: Implement Tap Gesture: A single tap will change the color of a circle. Implement Swipe Gesture: We’ll detect horizontal swipe gestures to move a card left or right. Implement Pinch Gesture: Pinching will resize an image interactively. import SwiftUI

struct GestureRecognizersView: View {
    @State private var circleColor = Color.blue // Color for tap gesture
    @State private var offsetX: CGFloat = 0.0 // X-offset for swipe gesture
    @State private var scale: CGFloat = 1.0 // Scale for pinch gesture

    var body: some View {
        VStack(spacing: 40) {
            // Circle with Tap Gesture

Day 12: Mastering Gestures – Swipe, Tap, and Pinch ✋ Day 12: Mastering Gestures – Swipe, Tap, and Pinch In my twelfth post of the #30DaysOfSwift series, let me tell you about the Gesture Recognizers in SwiftUI. They are swipe, tap, and pinch that can bring an intuitive feel to your app, making it engaging for your users. Steps to Add Gesture Recognizers: Implement Tap Gesture: Implement Tap Gesture: A single tap will change the color of a circle. A single tap will change the color of a circle. Implement Swipe Gesture: Implement Swipe Gesture: We’ll detect horizontal swipe gestures to move a card left or right. We’ll detect horizontal swipe gestures to move a card left or right. Implement Pinch Gesture: Implement Pinch Gesture: Pinching will resize an image interactively. Pinching will resize an image interactively. import SwiftUI

Swipe, Tap, and Pinch Gestures in iOS 18 - #30DaysOfSwift

Day 11: Embrace the Night 🌙 For the eleventh post of the #30DaysOfSwift series, I am adding a Dark Mode Toggle to switch between Light/Dark modes in SwiftUI. SwiftUI natively supports Dark Mode, and today, we'll create a sleek, minimalistic UI to let users toggle between the two themes. Steps to Add a Dark Mode Toggle: 1. Create a Toggle Button: Add a toggle switch in the settings view that allows users to manually switch between light and dark modes. 2. Customize the Appearance: We'll implement a system that changes the app's color scheme using SwiftUI's @Environment(.colorScheme) modifier. import SwiftUI

struct DarkModeToggleView: View { 

@State private var isDarkMode = false // State to track the mode

var body: some View {
    VStack {
        // Title Text
        Text("Dark Mode Toggle")
            .font(.largeTitle)
            .fontWeight(.bold)
            .padding()

        // Example image to showcase the mode effect
        Image(systemName: isDarkMode ? "moon.fill" : "sun.max.fill")
            .resizable()
            .scaledToFit()
            .frame(width: 100, height: 100)
            .foregroundColor(isDarkMode ? .yellow : .orange) // Custom color for each mode
            .padding()

        // Toggle switch with label
        Toggle(isOn: $isDarkMode) {
            Text(isDarkMode ? "Dark Mode" : "Light Mode")
                .font(.headline)
        }
        .toggleStyle(SwitchToggleStyle(tint: .blue)) // Beautiful blue accent color
        .padding()

    }
    // Apply the color scheme dynamically
    .preferredColorScheme(isDarkMode ? .dark : .light)
    .animation(.easeInOut, value: isDarkMode) // Smooth transition between modes
    .frame(maxWidth: .infinity, maxHeight: .infinity)
    .background(isDarkMode ? Color.black : Color.white) // Set background color based on mode
    .edgesIgnoringSafeArea(.all)
}
}
