Course Description
Control flow is how you make your program’s logic operate. It’s one of the most important skill sets in software development. Having your logic move from one condition to another and then evaluating the results of that movement is a core skill. In this module, you’ll learn different methods of control flow. We will cover checking for different conditions in your code with If and If-Else control flow structures. You’ll also learn about logical operators and how you can use them to determine equivalency and comparison in Swift.
You’ll also learn about the switch statement. Switch evaluates a certain condition and then checks for cases within that condition. As your code goes from case to case in the switch statement, you’ll be able to run code depending on the case. This is oftentimes a more efficient way of writing your code compared to a series of nested IF statements.
What You'll Learn
- Describe control flow and how program logic moves from one condition to another
- Use If and If-Else control flow structures to check for different conditions in your code
- Apply logical operators to determine equivalency and comparison in Swift
- Identify switch statements and evaluate cases to run code depending on the case
- Write loops to control the flow of your Swift programs
Key Takeaways
- Control flow is how you make your program's logic operate and is one of the most important skill sets in software development.
- If and If-Else control flow structures let you check for different conditions in your code.
- Logical operators are used to determine equivalency and comparison in Swift.
- A switch statement evaluates a condition and checks for cases within it, running code as it moves from case to case.
- Using a switch statement is oftentimes a more efficient way of writing code compared to a series of nested If statements.
Frequently Asked Questions
What does this Swift course cover?
