Tutorial: Getting Started with Vision on iOS 11!

Apple introduced Core ML the new machine learning framework at WWDC 2017 and included with it is a new vision framework providing high-performance computer vision features for tasks such as image and face detection.

Check out this starter tutorial from Jeffrey Bergier who shows you how to get started with the Vision framework and perform object detection on a live video feed.

Tutorial: Getting Started with URLSession!

The URLSession class provides an API for downloading content via HTTP by offering a rich set of delegate methods to support authentication & to give your apps the ability to perform tasks in the background. If you have been using URLConnection in the past or have been using a third party library like Alamofire, then you should take a second look at the much improved URLSession class.

Check out this excellent tutorial written by the folks at Raywenderlich to find out more about URLSession.

Server Side Swift vs. The Other Guys

The battle for the best server-side framework is just getting started, and Vapor which is a server side framework implemented using pure Swift is giving the big guys a run for their money.

Vapor surprised us with how close it got to Go. The pure Swift HTTP server Vapor uses is thread based where as Go uses coroutines. Coroutines can be a lot faster but require additional libraries and setup. Its possible Vapor could adopt this type of parallelism in the future. (Read more about threads vs. coroutines in the code section).

Additionally, Swift on Linux is still beta and compiles with unoptimized toolchains. As the compiler nears production in the coming months, Swift has the possibility to dethrone Go.

Tutorial: Introduction to MVVM in Swift 3 With Code!

In recent times the MVC (model-view-controller) design pattern has lost its place as a de facto pattern ever since better architectural patterns have come to light.  MVC is now infamously called a Massive(or Messy)-View-Controller pattern, the reason for that is it’s very easy to pile up 1000+ lines of code inside a View controller. Even Apple is famous for shying away from following the MVC pattern in their sample code. MVVM (model-view-viewModel) is an architecture pattern that is an alternative to MVC which makes it easier to further isolate the UI specific responsibility of a ViewController to a View Model.

If you are new to MVVM and want to know more about how to implement one, then check out this great in-depth article by Erica Millado linked below.

How to open Deep Links, Notifications, and Shortcuts!

Deep Linking is becoming quite prevalent in apps these days and it’s important for developers to have an understanding of it. Deep linking consists of using a hyperlink that links to a specific piece of content within an app. The specific content could be a page, view, or a certain tab. You can deep link from another app or even from a website to your app. Check out this excellent article by Stan Ostrovskiy who explains the concept with some easy to understand sample code:

Developers Who Use Spaces: Make More Money Than Those Who Use Tabs!

It’s amusing to see someone take so much time & effort to conduct a survey of this kind; but what a conclusion! Interestingly, more people use spaces than tabs, which is hard to believe.

There were 28,657 survey respondents who provided an answer to tabs versus spaces and who considered themselves a professional developer (as opposed to a student or former programmer). Within this group, 40.7% use tabs and 41.8% use spaces (with 17.5% using both). Of them, 12,426 also provided their salary.

Analyzing the data leads us to an interesting conclusion. Coders who use spaces for indentation make more money than ones who use tabs, even if they have the same amount of experience.

Phased Releases: in iTunes Connect!

A nice new feature announced at WWDC this year was phased releases. This is the new ability to be able to gradually release your app update to users over a period of 7 days. This has long been the envy of iOS developers looking over at their Android developer colleagues. Phased releases don’t quite have the same flexibility as the Android staged-rollouts but it is certainly much better than releases to potentially millions of users simultaneously.

Easily lookup App Store trending keywords – Appkeywords.io!

Appkeywords.io is an online tool that can help you quickly look up App Store search results just by typing a few letters of the keyboard. It’s an excellent tool to do research on the keywords like what keywords are trending in a particular country. You can also select your favorites from the list and copy them to your clipboard as a comma separated list or download them as a csv file. The website also provides great advice on how to pick the best app keywords.

Port: Your iOS App to macOS!

If you are an iOS developer and are thinking about developing apps for macOS but felt daunted, then its time to think again. Your iOS development skills will come to great use when you are developing apps for macOS and the best part is that you can reuse a significant amount of the code between the 2 platforms and only having to rewrite the portions that are platform-specific.

Check out the article linked below that takes you through the process in detail:

Tutorial: Core Machine Learning for iOS Developers!

Machine learning is a technology that’s been there since 1950’s but it’s all the rage today. It’s being increasing adopted in many industries, not just at tech companies. Many people have heard about it, but only a few know what it is. Apple has made available a ton of great resources covering Cover ML including their in-depth documentation along with 2 WWDC sessions – Introducing Core MLCore ML in depth.
