Advanced Control Flow

Building on the basics from Chapter 5, this chapter covers Swift's more powerful control flow tools: for-in loops, ranges, the versatile switch statement, and pattern matching -- features that make Swift code both concise and expressive.

For-In Loops

The for-in loop is Swift's primary way to iterate over sequences:

for i in 1...5 {
    print(i)  // Prints 1, 2, 3, 4, 5
}

Full content for this chapter will be added in a future update. The complete article covers ranges (closed and half-open), for-in with collections, where clauses, switch statements, pattern matching, tuple matching, and labeled statements.
