Are you considering making your own app? This is what you need to know. Learn about the app ecosystem, programming languages, tool sets, and time and effort involved. Let’s not tell you what you should know, but rather explain how you can actually get started today to get an app published in the App Store.
An app is just a piece of computer software running on a smartphone. It’s written by a programmer, and put together with graphic assets created by a designer.
Apps for iPhone are made with a Mac application called Xcode, and programmed in either Swift or Objective-C. Many apps are connected to the internet, which means that they have a back-end that allows storage of data in the cloud or functionality that interconnects users.
Xcode is the application you can use for making native iPhone apps, and it’s only available for Mac OS X. It includes Interface Builder, a tool to visually create the graphical foundation of your app. It’s a scaffolding tool: you can’t make a functional app with it, but you can lay down the groundwork for the GUIs of your app.
