This article has been developed using Xcode 11.4.1, and Swift 5.2.2

Coding is important, as you are building a product. Testing is also a crucial part of creating code, that is you are creating a project that is validated and in some sense correct.

Debugging helps you to work out those little problems and errors that exist in your project.

How are you going to do that, why are you going to do that and what does it give you?

Prerequisites:

• You will be expected to be aware how to make a Single View Application in Swift, including adding UILabels and UIButtons
• The code uses Force Unwrapping liberally, avoiding that is covered HERE
• I’ve made the keyboard resign with THIS technique

Terminology

Breakpoints: a debugging tool that allows you to pause the execution of your program at a specific point in time

Why?

We all make mistakes. In programming these mistakes are often known as “bugs” that get into our software and cause problems.
