I can imagine this article's title made you think: what is a keyboard layout guide? I've never heard of it! Is there a marvelous yet hidden API in the iOS SDK that significantly improves keyboard handling? The answer is: unfortunately not. This article is about a solution that I have been using for at least three years, and it is surprisingly simple and works pretty well. But let’s start from the beginning.

Hello SwiftUI! June 2019 was mind-blowing for the Swift Developers Community. During WWDC, Apple announced a brand new framework for creating UI – SwiftUI. Long story short, it’s a declarative framework that can massively reduce the time needed for creating and refactoring views in our apps. This blogpost is meant for people who already have a basic understanding of SwiftUI. Otherwise, a good primer on the subject is the WWDC 2019 session number 204 – read this first and then come back here!

Introduction Recently, our iOS security team was looking for a security analysis tool and we tested MobSF as one of our solutions. MobSF is a tool recommended by OWASP in its Mobile Security Testing Guide. It has binary analysis, source code analysis, and dynamic analysis, but sadly dynamic analysis is only available on Android. MobSF has many security testing options and has really great potential. There was one problem though, it only supported Objective-C for iOS code analysis.

ARKit Continuation

Recently I published an article with the entrance to the ARKit which briefly presented the minimum knowledge that is needed to create something inside augmented reality. We know what is the ARSCNView for, why we need to implement the ARSCNViewDelegate and how to run the ARSession. The demo was pretty straightforward as its main purpose was to receive information from the camera and detect the currently visible surface by attaching proper graphic onto it. User interaction was only limited to pointing the camera at desired spaces and waiting for the results that were calculated on the fly.

For people that are not very familiar with that technology, it may seem a little bit overwhelming to dive into augmented reality world and start developing all of the new features that are available right now. Fortunately, things are not that bad at all and in this short blogpost I will try to present it to you.
