Playground is one of the most popular features of Xcode. It’s an interactive development environment that allows developers to carry out simple experiments using the Swift programming language and see the output of their code in real-time.

In your programming journey, there may be times when you’d like to try a new package. In my case, I stumbled upon “Announcing Swift Algorithms” on the official Swift website. As I looked through it, I came to know about the new features that Swift Algorithms package offers. This made me quite excited to get my hands dirty! …

If you’ve been following WWDC20, then you totally understand how huge this edition of WWDC has been for the whole Apple ecosystem, users, and developers. With the announcement of iOS 14, many handy features are on their way to spice up the iOS experience. One of such features is Widgets.

I know this doesn’t sound new for Android users, but this definitely is great news for iOS users. Now, developers can create widgets of their applications by making use of the new WidgetKit framework. As of now, it is in Beta and available in Xcode 12 Beta and above.

Note…

“An else block can exist only when an if block exists before it.”

As a programmer not belonging to Python background, I was a strict follower of this rule. But I was left awestruck and confused after I saw one of my friends’ Python code that used an else block after a for loop. So, I performed some research and found that Python provides a feature, that allows us to use an else block with for and while loops. The else block after a for or while loop is executed only when that loop is not terminated by a break…

Consider this piece of code:

Here, we’ve created a struct named Car with five properties: model, brand, releaseDate, price, designerName and isExpensive.

Let’s create some instances of this struct and store them in an array, cars:

Note: The names of the cars and their properties do not resemble the cars in real world.

If we want to retrieve the models of all the cars in the cars array, up to Swift 5.1, the syntax would be as follows:

let carModels = cars.map({ car in
    return car.model
})

Or, if that developer is a bit lazy (like me!) or…

Push notifications are one of the most popular ways for developers to keep users engaged in their apps. In iOS applications, push notifications can be incorporated by using the Apple Push Notification service (APNs).

However, it’s not as easy as it sounds since there is a long list of things to do for setting this up. Plus, what’s worse is that we have to use a real device to test if push notifications are working or not since push notifications aren’t supported in Xcode’s iOS Simulator.

But I have some good news for you. Xcode 11.4 beta is out and…

On November 7, 2019, an announcement was posted by Shreyata Karmacharya, the Engineering Manager of Insight Workshop, in the official Skype group chat of the company. It was about an internal hackathon, “IW Hack Fest 2019”, that was scheduled for November 23, Saturday. With that announcement, a wave of idea hunt started in each of our minds. However, a group of 3–5 had to be formed before registering, so I went on a lookout for my hackathon mates. Initially, I had thought that it wouldn’t be that difficult to form a group of like-minded individuals for a common goal. But…

This is the third and the last part of the series “Implementing Sign in with Apple Using Django: A Recipe,” which has been written to share a clear path for developers to implement the Sign in with Apple feature in their iOS apps with Django in the back end.

3. Implementing Sign in with Apple in Your iOS App

Now, the only step remaining to be done is in the iOS app itself. In Part 1 of this series, we added Sign in with Apple to our app’s…

This is the second part of the series “Implementing Sign in with Apple Using Django: A Recipe,” which has been written for showing a clear path for developers to implement the Sign in with Apple feature in their iOS apps with Django in the back end.

2. Making the Back End Ready by Implementing Sign in with Apple

For implementing Sign in with Apple on a Django-powered back end, we’ll need a server running a project of Django 2.0 or above, with Python Social Auth. …
