How Can Swift Skyrocket My Career?🚀
Some main reasons might be; supporting the worlds most profitable company (Apple), high in demand, well paid, a highly paid professional, to build the mind of an engineer, to solve problems, to increase your salary by tens of thousands of pounds / dollars.
Dedicating a portion of your life to writing and maintaining software for Apple devices (one of the most successful companies on Earth) might be a good choice for any young professional. I can certainly say that back in 2007 (when the iPhone was released) it was certainly a life-changing decision for me. My career both started and exploded. I received as much from it equal to the effort I put in to it.
Become an iOS Developer maintaining existing apps in the tech industry. Why not think about what it can do for you?
Becoming a QA (Quality Assurance - testing team) is also an ideal option, however, programming is just so rewarding that we highly recommend pursuing it.
The salary is high. You are one of the staff who directly affect the product i.e. you are VERY VALUABLE to the company. You can ask for pay rises, more time off, a sabbatical if you want. Work from home and travel if you want.
Yes, working as a software engineer really does have its rewards. Also dedicating my language of choice to support one of the richest and most stable companies in the world might be a better life strategy than dedicating so much time to others.
Swift is the language of choice for creating all Apple apps that run on iOS and macOS devices.
Learn Swift by enrolling for free in a 3-day online course. The first 3 lessons are free and exist as a preview of course style, taught by one of the worlds most experienced iOS Developers and international consultant.
Tips to Sky rocket Your Swift Career 🚀
Focus on learning the Swift language itself. Most team members start their learning journey by studying Xcode and building apps. It's a lot of information and plenty to get confused about. Most of your colleagues will have many gaps in knowledge that affect their every-day anxiety with completing tasks and having it reviewed by others. Instead, why not become the one of the reviewers? Our advice is to stand out in the tech industry and if you want to stand out I would suggest becoming very knowledgable about the language itself; Every single developer will be using it and they will all be competing over Architecture and not the best use of language features. Armed with an incredible understanding of the language you will have the confidence in knowing you can maintain any existing product on the market.
Gather "Career Things" like they were collectibles in a game. This easy-to-remember and rather broad term is a great bit of advice. Too many engineers let the months go by without really taking on board many exciting projects or doing anything that wows any one. This is a terrible idea in every way. Stand out. Be the best at something (like understanding the language). When you change positions and apply to a different company you will have an interview and they'll grill you with many questions. The main bits to know are these; Your CV gets you the interview. You display your worth in the interview.
Your CV gets you the interview: Your short 2 page bullet-pointed CV is simply a list of amazing things you did to improve the team, the social element, the code quality, the income, how you increased user retention, how you added a successful feature and improved the app. You must collect career things.
You display worth in the interview: In the interview you want to fill the hour with saying similar phrases non-stop to "I was able to tweak the values and affect the income of the product simply by reducing the friction of the onboarding and providing a more seamless and pleasant user experience for the user. We now have only a 14% drop compared to most companies that have around 30% typically." Notice how you use "we" when referring to your current company in interviews. To simplify the phrase just-used, "I helped my company move forward. I improved the product, which led to an increased user experience and ultimately more profits for the company. I am a team player and I will improve your company at every opportunity possible."
Become confident in Interviews. You are now a talented Swift engineer who understands the Swift language and has a list of successful results you can pull out of the bag and discuss and any interview. You are constantly and infinitely talking about specifics of the Swift language and how cool and useful it is. You are stacking up one example after another of how you affected the results of the team and the company. You are great at telling these stories. The world is your oyster and you can be confident in your abilities as well as your choices in life.
Move company every 2 years. Ask for a £10,000 increase. When you become bored at your current job because you know too much think about moving, upgrading your job title and doubling your annual salary.
Be driven and be proud that you help keep the world moving by maintaining the digital services we all love and are constantly glued to.

Ever Heard of an Optional in Swift?
Learn about it below.
In Swift an optional is a type made using an enum with two scenarios; none and some. "None" can also be represented by a special keyword "nil". "Some" has a variable attached to it. If we want to retrieve the variable then we can extract it through something called optional binding (although other options exist also).
enum Optional<T> {
case some(T)
case none
}
let containsAValue: Int? = 100
let noValue: Int? = nil

Optionals are explained in our 3-day online course. Enrol here.
Below is a rough format of how optionals are declared, checked to see if they contain a value and also extracting that value.
// 1. How to use the Optional type
let optional: Int? = nil
// 2. How to check if the variable is empty
if optional == nil {
}
// 3. How to check if the variable contains a value
if optional != nil {
}
// 4. How to extract an existing value
if let value = optional {
print("Value: \(value)")
}
Optional Binding
Optional binding is the best method of checking to know if a value is contained within the optional as well as actually extracting it if one exists.
The if statement performs the comparison whilst also extracting the associated value and placing the contents into a newly created variable made available to the code within the if statement.
// 1. How to unwrap stored values
let exam1: Int? = 55
if let exam1Score = exam1 {
print("Exam 1: \(exam1Score)")
}
The Problem Optionals Solve
In code we often do not have a value and at some point in the future we may populate this field. Numerous reasons exist for this, such as if a user has a middle name, or extra data has not been downloaded yet.
In the example below, we can see that an empty string is used to represent the absence of a value. However, this is not the absence of a value and is in fact a value, but empty. This empty string is a valid piece of data and would be foolish to introduce a "marker" to signal that in this event we can assume the data is missing rather than being empty (sometimes it's valid for the data to be empty).
Nil provides us with a Swift-supplied signal that our data is missing. When we have actual data (whether its empty or not) we can extract it and use it knowing that what ever it is, it is the fully downloaded and ready information.
// 1. The problem optionals solve
let stringValue: String = ""
if stringValue.count > 0 {
print("Value: \(stringValue)")
} else {
print("No value found")
}
What Other Topics Do I need to Learn?
Foundational types, control flow, optionals, functions, closures, classes, structs, enums, value types, reference types, ARC (Automatic Reference Counting), extensions, protocols, concurrency, error handling and generics.
Below is the full list, available to download in markdown language.

The recommended topics to study are those that each iOS Developer would be required or expected to know in order to pass an interview for a junior, mid-level or even a senior role.
