Amidst all the fanfare of another WWDC, Apple introduced us to iOS 12. This is one of the most focused releases for both consumers and developers, emphasizing performance optimization. As well as this focus on performance and optimization, iOS also bringssome feature iterations on many of the libraries we know and love. This includes the evolution of emojis (with memojis), Siri shortcuts, augmented reality and machine learning.
In the previous tutorial of this series, we added the ability to add, update, and remove shopping lists. A shopping list without any items in it isn’t very useful, though. In this tutorial, we’ll add the ability to add, update, and remove items from a shopping list. This means that we’ll be working with references and the
In the first tutorial of this series, we explored the CloudKit framework and infrastructure. We also laid the foundation for the sample application that we’re going to build, a shopping list application. In this tutorial, we are focusing on adding, editing, and removing shopping lists.
Back in 2012, Apple introduced iCloud alongside iOS 5. At the same time, the company announced that developers would have access to iCloud through a number of APIs. Up until now, developers have had three options:
Beyond enabling iOS developers to easily store data on the cloud, as well as authenticating users through their robust SDKs, Firebase also provides a convenient storage solution for media. Firebase Storage allows developers to store and retrieve audio, image, and video files on the cloud. That is, Firebase Storage exposes a set of SDKs to give developers the ability to manage their user-generated content assets alongside its sibling product, the Firebase Realtime Database, which stores user text content.
Developers are constantly striving to make their apps more advanced, but are they actually usable by everybody? For most apps, the answer is no. In order to reach the largest audience, let’s learn about ways to make our apps more accessible.
In my previous article about secure coding in Swift, I discussed basic security vulnerabilities in Swift such as injection attacks. While injection attacks are common, there are other ways your app can be compromised. A common but sometimes-overlooked kind of vulnerability is race conditions.
From minimizing pointer use to strong type checking at compile time, Swift is a great language for secure development. But that means it’s tempting to forget about security altogether. There are still vulnerabilities, and Swift is also enticing to new developers who haven’t yet learned about security.
This year’s WWDC announcements focused on the exciting new SDKs, such as ARKit, and the changes to iOS 11. However, Apple has also made significant improvements to Xcode with Xcode 9. Not to be outshone by the other announcements, the new version of Xcode is a leap forward for coders. Developers are sure to be happy!
Apple’s latest IDE version, Xcode 9, is being released along with iOS 11 this September. And it’s a huge update! Fans of Git for source control management (SCM) are big winners in this upcoming release.
The main purpose of a digital signature is to verify the integrity of some information. For a simple example, let’s say you had a file that was transferred over the network and you want to check that the entire file was transferred correctly. In that case, you would use a checksum.
You have worked weeks or months on your first iOS application, and you are ready to submit your masterpiece to Apple’s App Store. How do you do this? Is your application ready for submission? I am sure that some of these questions have entered your mind at one point or another.
In this tutorial, you’ll be learning about the CocoaPods dependency manager and how to implement it in your app. We’ll go through the steps from creating an Xcode project all the way to importing frameworks. Along the way, we will learn about some basic Terminal commands and what they do.
