Everywhere you look, you are being told to write unit tests, but what even are unit tests? Here, we look at what testing is, why you need them, who should write them and when to write them. And ulitmately how unit tests allow you to go faster.

A lot of developers rely on intuition to identify the test cases that exist in their apps. This approach leads to inconsistent coverage, missed edge cases and bugs. Here, we look at how to ditch the intuition approach and get systematic in our identification of test cases.

Testing isn’t one hurdle but a series of lenses - unit, integration, system, and acceptance. Each reveals different truths and mitigates unique risks. Together, they form an ecosystem of trust that helps teams ship with confidence. Here, we look at that ecosystem.

You are a great developer, so why go through the hassle of writing unit tests? Here, we look at the reasons beyond writing unit tests and how to win over a unit test sceptic

Dependency injection is one of the superpowers that developers can utilise to produce code that is more predictable and easier to test. Here, we look at dependency injection - what it is and how we can utilise it.

Oversharing is bad. Social media taught us this. But so did '101 Introduction to Object Oriented Programming'. Here, we look at how to avoid oversharing by designing our types to be defensive.

We've all written delegates, but sometimes our delegates require more information than what we receive from UIKit. Why is this? Here, we look at how conforming our protocol to NSObject brings us closer to UIKit delegates.

Working with stringy APIs is prone to runtime errors, as the compiler can only enforce that a string is there or not, rather than if the value is correct or not. Core Data loves a stringy API. Here, we look at how to enhance the compiler's involvement with Core Data by de-stringifying the API.

Sorting is fundamental to any app. Here, we look at going beyond simple sorting with `NSSortDescriptor`.

Making a network call and consuming the response is common to most app. But how do we do it? Here, we look at building a networking layer to consume an XML response.

Sometimes, when you need to know, you need to poll. Here, we look at building a polling mechanism using `NSOperation`.

Waiting for something to load is boring but we all have to do it from time to time. Here, we look at how to build a custom loading view that can be reused throughout your app.

Manually scrolling through a list of information to find what we need can be time-consuming, even for modestly sized lists. Here, we look at how to search through a list to find what we need using `UISearchBar`.

Moving work onto a background thread can be hard. Here, we look at how to keep it simple.
