When building out your application in Swift, a lot of developers may encounter runtime errors when building their application. A very common cause for runtime errors is that the value that is being requested is nil. This means that the application is requesting a value that does not exist. The compiler doesn’t know how to handle this case and therefore creates a runtime error, crashing your application.

There is an easy way to avoid this runtime error by utilizing optional chaining. …

Most iOS developers have been tuning in to WWDC this week to catch all the latest updates and features being made available from Apple. Today we are going to do a run down on some of the awesome new features that are coming to SwiftUI 3.0 and what they do.


SwiftUI 3.0 brings the refreshable() modifier to developers. This modifier allows you to attach functionality to a List object in SwiftUI that occurs when the user drags the screen down far enough to trigger a refresh. We can take an example of the implementation of this modifier below:

As an iOS developer, you have likely already encountered protocols in either projects you have made, or other projects you have looked at. But why do developers use protocols? What exactly do they do and why are they useful? Today we are going to dive into protocols and learn how to use them in your next Swift project!

Protocols are used to create a core structure for an object in Swift. This structure is similar to that of a class, but one of the main differences is that you only define what functions are associated with a protocol, not the…

When building out your first applications in Swift UI, you are going to quickly encounter the need to utilize buttons in order to achieve different functionality within your program.

When creating a button, it can be a bit daunting to remember the syntax needed and how to format it appropriately as it is quite different than creating actions within UIKit. Today we are going to cover the syntax and application usage for buttons within Swift UI so that you will be prepared to take your application to the next level.

When working with Swift UI, you are likely going to need to pass some data in between your views that may be being stored or used within another view. This process can actually be achieved pretty easily by passing the data through a closure statement with calling the next view. We are going to dive into this subject today so that you are able to easily pass data from one view to the next!

Closure Statements:

When passing data through closure statements, it is important that the view receiving the data is setup to actually utilize that data and accept…

Today we are going to cover an important process in developing applications with Swift UI, how to navigate between views. When developing applications using UIKit, developers typically utilized segues to navigate between views. In Swift UI, we use a different method of navigation called Navigation Links.

Getting Started with Navigation Links:

The first thing that you will need to do to use navigation links is to wrap your view in a navigation view. You can do so by using the syntax in the following example:

struct SomeView: View {
var body: some View {
NavigationView {

During my time at Apple, one of the biggest areas of confusion that I saw was developers trying to choose the correct method for distributing their app. Apple offers many different ways to distribute applications and each one has a specific purpose. Today we are going to dive into the different methods of distribution and when to use each one depending on your distribution needs.

App Store Distribution:

The first type of distribution we will cover today is the most common type of distribution, App Store Distribution. To distribute an app on the App Store, you or your organization must…

Hello again! Today’s article is going to focus on spacers and padding within Swift UI. When you begin designing your user interface with Swift UI, you will notice that a lot of the elements you add are automatically being placed on the screen based on the type of stack you have created it within. Well what happens if you want to manually adjust the spacing between objects to achieve a desired look? This is where spacers and padding come into play. Today, we will talk about both options and when to use each one of them for your UI design.
