My name is Maribel Aristy and I’m a Christian software developer and graphic designer from Spain. I love structure and order, and I also stand for quality. I love spending time on fixing little details and optimizing web apps and websites, both code and artwork.
Much of my best artwork and design has been completed under confidentiality agreements at the various agencies I’ve worked for. Please find some of the work I’ve produced in my free time as personal projects in posts under the category “Art”. You’ll notice that biblical values are an important part of my graphic designs. I truly believe that the word of God must be shared with all and my graphics are one way of doing this. Here you’ll find clothing with Christian messages, stickers, etc.
Now, back to programming, I work with Swift, HTML, CSS, and some PHP and I also love teaching. That’s why you’ll find a guide here to learning Swift 4, which is one of the topics I cover here.
This is the perfect starting point for learning to create apps that run on iOS devices, using Swift 4. You will also find the tools, major concepts, and best practices that will ease your path.
Each lesson contains a tutorial and the conceptual information you need to complete it. The lessons build on each other, walking you through a step-by-step process of creating a simple, real-world iOS app.
It is assumed that you are familiar with the Swift programming language. You do not need to be a Swift master to complete the lessons, but you will get more out of the lessons if you can comfortably read and understand Swift code, which you can read and get familiarized on: Swift Playground which will help you ‘practice’ Swift. Also, if you need background (or just start from zero), please read The Swift Programming Language (Swift 4) from the Apple website. Both will give you a solid foundation to start.
