Swift Tutorials: Labeled Statements 🎯

Welcome back to CodeYourCraft! Today, we're diving into Swift's Labeled Statements. Let's get started! 🎉

What are Labeled Statements? 📝

Labeled Statements are a way to give a name to a specific part of your Swift code. This can be incredibly useful for navigating complex control structures like loops and functions.

swift

myLoop: for i in 1...10 {
    // Your code here
    if i == 5 {
        break myLoop // Exit the loop at this point
    }
}

In the example above, myLoop is a label we've given to our for loop. We can use this label to break out of the loop at a specific point, like when i equals 5.

Labeled Break and Continue 💡

We can also use labels with the continue statement to skip over the current iteration of a loop.

swift

myLoop: for i in 1...10 {
    if i == 3 {
        continue myLoop // Skip the current iteration if i equals 3
    }
    print(i)
}

In this example, when i equals 3, the loop skips that iteration and moves on to the next one.

Nested Labeled Statements ✅

You can even have multiple labeled statements nested within each other. This allows for more complex flow control in your Swift code.

swift

outerLoop: for i in 1...10 {
    innerLoop: for j in 1...10 {
        if i == 5 && j == 5 {
            break outerLoop // Exit both loops when i equals 5 and j equals 5
        }
        print("i: \(i), j: \(j)")
    }
}

In the example above, we have an outerLoop that contains an innerLoop. When both i and j equal 5, we break out of both loops.
