The Careers team at Udacity is here to help you move forward in your career - whether it's finding a new job, exploring a new career path, or applying new skills to your current job.

Learn about one of the most basic building blocks of nearly every programming language. Variables give developers the ability to store information that can be used to control the behavior.

Add, subtract, multiply, divide, and more using operators and expressions in Swift!

Learn how to control when and how Swift code is executed by using if and else statements.

Learn how to define and use functions, which give developers the ability to bundle up code so that it can be reused multiple times.

Learn how to declare and use structures, or structs, in Swift, and explore Enums, a type that can represent any value in a set of related values.

Why does Swift need this data type that no other language has? Join us as we get to the bottom of this mystery, and learn optionals inside and out.

Playing with Strings is a lot of fun. In this lesson, we'll explore Swift’s String struct, and practice some common string manipulations.

It’s time to explore collection types, including Arrays and Dictionaries.

Learn foundational concepts of object oriented programming, including classes, inheritance, and polymorphism.

An introduction to Swift and Xcode. Swift is Apple's fast-growing programming language for building iOS apps and much more. Xcode is the programming environment used to create native Apple applications with Swift.

Learn how to store your code on Github, and review Swift syntax if needed, before proceeding.

Version control is an incredibly important part of a professional programmer's life. In this lesson, you'll learn about the benefits of version control and install the version control tool Git!

Now that you've learned the benefits of Version Control and gotten Git installed, it's time you learn how to create a repository.

Knowing how to review an existing Git repository's history of commits is extremely important. You'll learn how to do just that in this lesson.

A repository is nothing without commits. In this lesson, you'll learn how to make commits, write descriptive commit messages, and verify the changes you're about to save to the repository.

Being able to work on your project in isolation from other changes will multiply your productivity. You'll learn how to do this isolated development with Git's branches.

Help! Disaster has struck! You don't have to worry, though, because your project is tracked in version control! You'll learn how to undo and modify changes that have been saved to the repository.

You'll learn how to create remote repositories on GitHub and how to get and send changes to the remote repository.

In this lesson, you'll learn how to fork another developer's project. Collaborating with other developers can be a tricky process, so you'll learn how to contribute to a public project.

You'll learn how to send suggested changes to another developer by using pull requests. You'll also learn how to use the powerful git rebase command to squash commits together.

In this lesson, learn how to tell your unique story in a succinct and professional way. Communicate to employers that you know how to solve problems, overcome challenges, and achieve results.

It's time to hone your UI development skills with AutoLayout, and draft your final project's user interface!

In this lesson, you will learn what problems AutoLayout solves and why you can't afford to ignore it any longer.

In this lesson, you will learn about the 4 different ways of implementing AutoLayout, which one we recommend you use, and why. You also will delve deeper into the recommended way: UIStackViews.

AutoLayout uses 3 properties that all views share: intrinsicContentSize, compressionResistence and contentHugging. Don't be put away by the weird names! It's actually pretty simple, and in this lesson, you'll learn all about them.

In this lesson, you will learn about 4 properties of StackViews that define its apparently weird behavior. Once you're done with this lesson, you will understand there's a logic to StackViews, and a lot of power too.

In this lesson, your will learn what a constraint is and well as the role of constraints in AutoLayout.

In this lesson, we will create simple horizontal layouts. These will be building blocks for more complex layouts.

In this lesson, we will take composition and vertical layouts to the next step and use them to create more complex layouts.

Before you leave, let's take a look at what you went through and what​ might be lying ahead.

Now that you know a bit more about UI elements available to you, sketch out some potential UIs for your final app ideas!

Start on your final project app, “On the Map.” Learn about network reliability, and how your app should behave if a network can’t be reached.

Revisit the concept of closures in Swift. Learn a few properties of closures bypassed in Swift Syntax but are vital when dealing with GCD.

Understand how and what tasks you can run in the background on an app and what must always run in the foreground.

Create a simple app that downloads huge images. Apply your newly acquired knowledge to send this network lengthy task to the background in two different ways.

In this project, you’ll pull in data from a web service to display a map with pins. Tapping on a pin will display a custom URL posted by another iOSND student at that location.

In this lesson, you'll build upon what you've learned about Firebase Analytics and explore crash reporting, remote configuration, and dynamic links — a suite of powerful tools for improving your apps.

Brainstorm and vet multiple app ideas. Think about the UI elements used in each, get user feedback on designs, and investigate relevant web APIs and libraries.

Choose an idea to pursue and build it! We'll share tips for getting started, dealing with code that doesn't work, and how to submit to the App Store.

Reflect on the process: what went well and what you might do differently next time. Recognizing and learning from mistakes is what makes you a better developer!
