Before we begin, let’s get started by answering the following question:
What is a type?The answer to this question is fairly simple—a type is a collection of related data that encapsulates certain concepts and principles. A type can be abstract or concrete, it defines a set of valid operations that we can perform on it, and finally, a type clearly demarcates the internal and external.

In this series, we’re learning about SwiftUI by making a profile page. And so far, we’ve accomplished a very simple—yet stylish—profile for ourselves in just a few paragraphs of code!

Gesture recognition helps us to know the meaning of human body movement, including the movement of hands, head, arms, face, or body. Today’s world is observing huge advances in visualization displays and this includes object trackers in AR applications.
The main purpose of this article is to explore gesture recognition in Facebook’s Spark AR Studio for an efficient human-computer interaction. It presents a method for tracking hand gestures and recognizing hand gestures by extracting unique invariant features from gestures.

Jonah Cohn doesn’t think Snapchat is going anywhere. One of the his so called “forever apps,” Snapchat has been part of the student’s life since 2013. Cohn must have found an endless supply of coffee because he’s not only a student, but a prodigious lens creator who’s active online in many digital creative circles.
I’d be tired making just one lens every few months, but he seems to churn them out one after the other — each one better than the last! Thankfully, Cohn had time to answer a few questions about his work so that we could learn more.

As much as our physical well-being is important, our mental well-being is essential as well. Many of us don’t really give as much priority to the mental health of ourselves and others. But mental health is a serious issue in today’s world, as many suffer in myriad ways.
Hence, motivation is very necessary. Positive thoughts and surroundings, while not a catch-all, can be one part of helping improve one’s mental perspective.
Over the past 3 years, our incredible community of contributing writers, developers, and creators have helped us explore the foundations of machine learning, mobile development, and where these two areas of tech intersect.
To date, we’ve published work from more than 150 individual contributors from over a dozen countries around the world — those voices have helped build an incredible library of foundational blog posts and articles that offer both beginners and seasoned developers educational resources, industry insights, research reviews, and much more.

Recently, I wrote two articles about training object detection Core ML models for iOS devices using TensorFlow and Turi Create frameworks.
To train those models, I used a tool I’d built called MakeML. It allows you to easily create a dataset, label it, and start training. There’s no need to write code with MakeML, so every iOS developer can train an object detection machine learning model in a couple of hours. On paper, at least…

Ever want to manage photo clutter on your phone? If you’re like me, desperately snapping several photos trying to get the best angles, pictures and videos slowly start accumulating on your phone. Eventually it runs out of memory, and you’re stuck deciding what to delete.

Generally, in machine learning problems, we often encounter too many variables and features in a given dataset on which the machine learning algorithm is trained.
The higher the number of features in a dataset, the harder it gets to visualize and to interpret the results of model training and the model’s performance. Moreover, when dealing with such a massive dataset in terms of features, the computational costs should be considered.

In part one of our series on SwiftUI, we began by making a simple profile page using SwiftUI. We got as far as:
Displaying our picture and name using Views Setting them in a VStack Apply Modifiers to have our UI follow basic design style guidelinesIn this tutorial, we’ll take it a step further. We’ll learn how we can continue to modify Views, including using other Views as modification parameters. We’ll also explore how we can create our own custom Views, which will help keep our UI code clean, readable, and reusable!
