Development for iOS *

Popular cloud hosting DigitalOcean has recently launched its new marketplace selling preconfigured images that can help to quickly deploy an application server. It’s much like AWS, but DO is for those already using this provider’s services. Let’s see how to deploy a simple server for WebRTC streaming with a DO account for a $10/month fee based on Flashphoner WebCallServer and how such a server can be of use.

Everything that follows from this point forward input prompts, followed by ChatCGP’s responses, complete with sample code in Swift.

Recently I wrote an article What is Reactive Programming? iOS Edition where in a simple way I described how to build your own Reactive Framework, and helped you to understand that no-one should be scared by the reactive approach. The previous article could now be named How to cook reactive programming. Part 0., since this is a continuation. I would recommend reading the previous article if you are not familiar with the reactive programming concepts.

There are many articles about Reactive Programming and different implementations on the internet. However, most of them are about practical usage, and only a few concern what Reactive Programming is, and how it actually works. In my opinion, it is more important to understand how frameworks work deep inside — spoiler: nothing actually complicated there — rather than starting to use a number of traits and operators meanwhile shooting yourself in the foot.

So, what is RxSwift Combine Reactive programming?

Instruments for Apple's Xcode is a tool for performance analysis of an iOS application. In 2018 Apple introduced Custom Instruments — an opportunity to expand the standard set of instruments for application profiling. When existing tools are not enough, you can create new ones yourself — it will collect, analyze and display the data the way you need.

Command-line interfaces (CLI) are a common way to use applications. In iOS, we usually use scripting languages like Bash or Ruby to build those CLIs and automate mundane tasks. The most popular CLI for app signing and build automation is, without a doubt, Fastlane, which was initially written in Ruby. Fastlane is a great tool, convenient and fairly easy to use, and a lot of effort came into building it.

However, there's a great chance you considered moving away from Fastlane to avoid learning Ruby and to lower the entry threshold for your developers. Setting up a Ruby environment could be quite tedious and require additional devs' expertise to write and support those scripts.

For iOS developers, WWDC is always something of a New Year. We are presented with so many new products, and sometimes you can get lost in them. Most of my colleagues are trying to be in touch by watching “Platform State of Union” and all “What’s new” sessions. The event basically provides an opportunity to developers a glimpse of the features to expect from the software part. When Apple has a conference like this one, they want to make sure they have enough time to get everything done. In order to do this, they need to be able to work at their own pace and not worry about how long it will take them to get something done.

This means that if you have a small project, it may not be that important but once you move into larger projects with more people involved, every second saved can be worth several dollars in terms of money saved or profit made by the company. The platform tightly integrates programming languages, frameworks, and tools. Everyone gains when these three complement one another. Customers receive a consistent experience, such as scrolling that feels right every time. And developers may devote more time and attention to what distinguishes the app.

And it’s fine, you don’t need to spend so much time for this other unpopular stuff. However, in these, not-so-popular videos as couple of them may be called as “hidden gems” because of the content or a beautiful presentation/structure. Let me show couple of them!
