First, remember create a new branch for the changes, we can do that using Xcode or the git(1) command-line tool.
iOS 13 introduced semantic colours, so UIKit already comes with support for automatic colour selection depending on the UserInterfaceStyle. So the simplest setup is to change our UIColor to semantic colours. For example:
Hello,
Welcome to issue #19, I hope you had a good start of the month.
As you might have noticed by my latest posts, I’ve been exploring the exciting field of cybersecurity. I’ve always enjoyed understanding the base components of what makes our cyber “life” work. Understanding the base components also ties up nicely with infoSec. So this week I wanted to share with you a couple of links related to cybersecurity. I believe that being aware of security makes us better developers and cyber-citizens.

But most of the time, the client would give us an IPA. In a black-box analysis, we won’t get access to the source code, so deploying it through Xcode to a Device for testing might be out of the question. One possible solution is to resign the app with a profile that we own and deploy it to our test device. In this post, I’ll explain how to re-sign an iOS app so we can generate an IPA that we can deploy to our test device.

Sure you can use any other third-party library, but sometimes simple is better. Also, it is always fun to explore and understand more of the process so you can be the judge on what works best for your case. In this post, I’ll show you how to work with XCUIScreenshot so you can have easier access to your screenshots and later you can build any scripts to process the screenshots.
Sometimes we only want to do the simplest of tasks of build and upload to TestFlight without having to spend much time doing lots of configuration. Maybe we are only testing a minimum viable product (MVP) and want to make it accessible to beta users. No matter the case, we also would like to understand the process behind the magic behind the graphic interface deployment. In this post, I’ll show the basic process of building and uploading an app to the Apps Store Connect(especially for TestFlight) using the command-line. And also, how can we automate it with a simple script and the tools already provided by Xcode.
Read More...At some point on your app development career, you’ll find yourself working with text fields to get some data from the user. Collecting data from the user sometimes involves additional work than merely reading text from an UITextField. For example, if we have a field at the bottom of the screen, and we show the keyboard, the keyboard might cover it. We have to do additional work to fix this. Like this, there are many other small tasks that we would perform while working with UITextFields. In this post, I’ll show how to handle some of the most common scenarios. I’ll cover:
Read More...If you decided to create an Extension for your app (maybe a Today Extension), you will quickly find out that you need to access data from your main app. And soon after, you will find out that you can’t access files in your main app directly from the extension. The process is not as easy as you thought when you started. The good news is that there are a few solutions, and they are not that complicated. In this post, I’ll show you how to use App Groups and embedded frameworks to create the bridge between your app and the extension.
Localization is not only translating content but adapting the content to culture, language and customs. This makes our apps more intuitive and engaging for our users. We can localize not only text, but we can also localize images, sounds, shortcuts, etcetera. A crucial part of localization is obtaining the text to be localized. In this post, I’ll focus on text extraction for localization. This post is not a general introduction to localization of apps, but when you finish reading the post, you’ll have a better understanding of crucial aspects of localization and can research other specific topics that you are interested in. As always, check my notes at the end of the posts where I add links and notes to explore related topics, let’s begin.
Read More...Each app in iOS has only one UIApplication object in charge of managing the app when your app changes state in its life cycle(e.g. activate, suspend, send to background, reactivate, etc.) it notifies it’s AppDelegate so it can run any task required by that change in state. In simple terms, the AppDelegate is in charge of ensuring that your app state changes are handled correctly, that the app is ready for each state change and will end up in a valid state when the event takes place.
Read More...To make the user experience better on iPad for multitasking remember that you can change the axis of your StackViews depending on the size class of your view or view controller.
Size classes represent the relative space of the view or view controller on the device. There are two size classes, compact and regular, this means Compact has limited space and Regular has the regular/normal space. So this is how it looks for iPhone and iPad
