Different App Display Name based on Xcode Scheme
In some projects is common to have “different builds” depending on the tester groups. I’m talking about situations where you need to have “different builds” using the same code base and with the same bundle identifier, for instance: “QA”, “Beta” and “AppStore” and a common way to identify them is to change the Display Name so our testers know what build are they testing. With a combination of Xcod
Cross-Platform mobile development with Swift
TL;DR, flip to the bottom for links… Recently I was asked to evaluate SCADE, which is a new IDE, one that has an intriguing value proposition: write your logic in Swiftcreate your mobile UItest and deploy native iOS .ipa’s…and native Android .apk’s…from one codebase.Yeah, I know there are others out there that do something similar, but this is Swift we’re talking about, not C#. And yes, you can us
Comparing the Performance between Native iOS (Swift) and React-Native
This article was reformatted for the React Native Log from my published Summa Cuma Laude thesis at the University of Florida. If you wish to read the original, here is the link: https://ufdc.ufl.edu/AA00058596/00001 React-Native is a cross-platform mobile framework that lets you build apps using only JavaScript. However, unlike other hybrid mobile technologies, you are not building a “mobile Web A
Introduction to Protocols in Swift 3
Hey Apple, what is a protocol? A protocol defines a blueprint of methods, properties, and other requirements that suit a particular task or piece of functionality. — Apple To me it reads: Read the definition again and call it a day. — Apple Hence, I am writing this article to clarify things up. Make things interesting at the same time too. We will use a UFC fighter example for our protocol later a
Why I created Rock for Swift CLIs – Valentin Knabel – Medium
Why I created Rock for Swift CLIsI excessively make use of the official Swift Package Manager as I usually do some CLIs or other stuff. For this use case it is really great. When developing Apps, Carthage and CocoaPods come in handy, which are great, too. For Web Development there are yarn and NPM, which support project based and global installs. Then there are gem (global) and bundler (project) f

Swift snippet #9 — then
You can find its Gist here! Whenever we have to safely unwrap an optional value, we generally have 2 options — if letguard letBoth solutions are great & there’s nothing wrong with them 👍 But I feel safely unwrapping could get little better 🤔 Thus I made an extension on Optional & created a function then which executes a closure having its unwrapped value only if some exists! It could be used som
Yammer iOS App ported to Swift 3
Since the introduction of Xcode 8 in late September, Swift 3 has become the default version to develop iOS and Mac OS apps. As an iOS shop, we had to consider a migration project to port our codebase from 2.3 to 3 while maintaining a good relationship with the Objective C part of the project. To Migrate or Not To MigrateThe first step was to decide if we wanted to migrate to Swift 3. In the past w
Hacking Atom to create a Swift IDE that runs on Linux and Mac
As of now theres no IDE available for swift that runs on linux which makes it kind of annoying to develop packages due to constant switching between text editor and terminal. I had never used Atom before but I wanted to see if it’ll live upto its name and let me hack it to integrate the Swift Package Manager and LLDB into it. Well, end result: Atom Swift DebuggerAtom is a text editor by Github whi
iOS + Swift + Parse + UICollectionView + Uploading files — Part 1 of 2
iOS 8.4+ Swift 1.2 Parse 1.7.4 Over the weeks and months I have had many people ask how they can use Parse with native UI components, how they can allow their users to upload images and other files to Parse, and, how to deal with users forgetting their passwords. I thought I’d wrap all these ideas and questions into a single tutorial and show how easy all of these features are to implement. Howeve
10 Swift IOS open-source projects you cannot ignore
If you are working on iOS, Swift is a great choice. It is elegant, easier to learn (than Obj-C) and powerful. (Update 9/30/16— This article is two years old. You should check out other stuff) You need to checkout these open-source projects if you want a headstart in Swift. The Swift Manual is comprehensive, but nothing like diving into code and learning from what is implemented. These are not in a
Apple has published a great free learn to code course for Swift — on GitHub
TL;DR: Apple has apparently, via some sort of collaboration with a university professor, published last week — during WWDC — a really solid-looking learn-to-code curriculum for Swift that is kind of on iTunes U but that is really on GitHub. I teach an introductory app design course at the University of Georgia’s New Media Institute. We teach mainly non-computer science students, and I had tried ou

Previous Posts Learn Swift by running ScriptsFunctional SwiftMore Functional SwiftJSON in SwiftIn this post we will write some HTTP wrapper functions. The Objective is that you can use them even if you don’t understand Objective-C. The three most useful functions are HTTPGet, HTTPGetJSON, HTTPPostJSON. I will leave it to the readers to write other HTTP functions. First we create function called HT

Sequence — beyond primitive iterations in Swift
IterationsOne fundamental brick in programming is iterations. All modern programming languages have them and swift is no exception. Just as it’s predecessor Swift offers the many varieties from C/C++ iterations, like do/while/for in different combinations but also offers a more modern approach with for/in (foreach in some other languages) for fast enumeration. Swift also offers a more modern synta
The Builder pattern in Swift
In recent days I started to use the “Builder Pattern” in my Objective-C projects, especially when creating multiple different instances of classes. I often use this when I am dealing with different color/font themes for my iOS apps. Before your read further I must admit that I yet have to fully read the Swift book from Apple, and I havent seen all their WWDC 2014 sessions. There are probably more
Facets of Swift, Part 1: Optionals
Facets of Swift is a series of articles on various aspects of the Swift programming language. I chose optionals as the topic for the first article, as these are one of the first features of Swift you will notice. The idea of optionals is simple: To prevent errors and to model things in code more accurately, Swift distinguishes between optional and non-optional values. What are Optionals?In Objecti
