Introduction to Mobile Software Development

This talks is aimed at A-Level students interested in finding out how they can pursue a career in software development. We start by looking at the different ways a business can approach building mobile applications in 2023. We outline what modern mobile apps are capable of, and what problems they can solve for customers. Then we'll turn to how you can build apps yourself, using software engineering skills and principles.

This talk delivered as part of the Isaac Computing Explorer Events on 11th October 2023.

  3. What is Software Engineering? Engineering is the use of science

    and maths to design or make things. Software Engineers build, design, and test programs for computers. They create websites, desktops programs, mobile apps, games… 📱 💻 🖥 🎮
  4. What do Software Engineers do? They write code in a

    programming language. This is called programming. There are lots of different programming languages!
  5. A programming language is like a tool in a toolbox.

    You need to understand what you are building and choose the right tool for the job. 🧰 🛠 I build Mobile Apps for iPhones and iPads. I use the Swift Programming Language. 📲 🤔 What do Software Engineers do?
