To start creating the shapes and animate them, we first need to start with the data we need to build the charts.
struct for the chart data. The data we need are the percentage, color, and a sum of percentages that come before the current percentage. We will need the sum when we use the modifier
.trim to start the trim from the last percentage value.
Now, we need to create an observable object. Add a published array of our chart data and populate it with data. Make sure your percentage adds up to 100 while testing. Assign all the chart data’s value to 0. …
In this tutorial, we are going to build an Instagram-like UI to demonstrate the redacted modifier’s functionality. The UI will include a post and one comment for simplicity.
First, we need to create a struct for the comment’s data. You will probably need to add a variable for the profile picture of every comment. For the tutorial, we are only storing the username and its comment.
Create a view with a horizontal stack inside it and add two concatenated
Text() views. Make sure the texts have leading alignment and the width of the screen by using
Neuromorphic designs consist of UI components extruding from the background. The UI elements are shapes made with the same material and color as the background.
In the article above, Michal Malewicz explains how to achieve this minimalist look. You need to use shadows in both negative and positive values. The background and UI elements should have the same hue. You should pick a color that doesn’t cover the light and dark shadows for this design to work.
To your project’s assets folder, add three new color sets by clicking the + sign. …
Create a struct of type
FileDocument. You will get an error message asking you to add the protocol’s stubs. Click “Fix” to add the required data. As you can see below, the protocol allows us to read and write documents through its
read initializer and
write function. You will also have the
readableContentTypes static variable that will help us determine and limit the types of files we want to allow in the app.
What we want to do next is assign our
UTType.plainText and create a new string variable to hold the user’s text input. …
Yes, many tech companies will have technical questions that don’t require you to add labels and text fields to an interface. If you want to work for big companies then expect your technical interview question to challenge your knowledge of algorithms.
There are some websites that provide coding interview practices such as hackerRank and geeksforgeeks. All of the technical interview questions you will find below are from LeetCode since I used to practice coding on it.
Given an array of integers
nums and an integer
target, return indices of the two numbers such that they add up to
You may assume that each input would have exactly one solution, and you may not use the same element twice. …
Let’s start by creating an enum for the bubble positions. Bubbles can be on the right or left side of the screen:
Now, we can create our model that stores our messages, bubbles’ positions, and the user input text. For this tutorial, we are going to store the last chat bubble’s position in a variable so we can alternate between the left and right bubble positions:
We need to create a chat bubble by utilizing
ViewBuilder. Inside our
body variable, we can create a bubble shape. …
Voice assistive technologies allow users to employ voice commands to communicate with their devices. Ensuring responsiveness to a particular user relies on precise speech recognition.
The input to such systems can consist of overlapping speech in many real-world use cases, which presents challenges to many speech recognition algorithms. Speech recognition involves addressing constraints such as model size, CPU, and memory limitations, as well as considerations of battery use and minimization of latency.
In VoiceFilter-Lite, google provides an upgrade to VoiceFilter that can dramatically improve speech recognition by using the recorded voice of a selected speaker in overlapping speech. …
We are going to use a 2D array to create the grid. Inside a
VStack, add a
ForEach loop that takes the 2D array. For each array of images inside our 2D array, add a second loop (from 0 to less than 3). Check if the index is not out of range, then add the
Image view. When the index is out of range, add an empty
Rectangle(). If you don’t want to use a
Rectangle(), then you can use leading alignment and re-center the grid.
Image view, add the
aspectRatio() modifier and set its content mode to
fill. Use the resizable modifier to be able to change the image’s frame, then add the frame modifier to adjust the size of the images. …
In this tutorial, we are going to create a custom list with two action buttons that will appear when you swipe a row to the left. We are going to start with one side button. It will be a delete button. Then we can add a second button to show how to add more buttons to the row.
Start a new iOS 14 project, then follow along.
Create a new struct of type
View and declare the following variables:
Text: Stores our row’s content.
index: The row’s index. Used to delete/hide a row.
width: The width of all the side buttons. Used to know how much to swipe to the left. …
