Simplifying Logic with Swift: From if-else to switch Pattern Matching

When working with conditional logic in Swift, you often encounter scenarios that require checking multiple conditions. Traditionally, developers rely on if-else statements for such tasks. However, Swift’s powerful switch statement with pattern matching offers a cleaner and more elegant way to handle these situations. In this article, we’ll demonstrate how to transition from a verbose if-else structure to a concise switch statement using pattern matching, … Continue reading Simplifying Logic with Swift: From if-else to switch Pattern Matching

Get Rid of `nil` Values using Dictionary.compactMapValues { $0 }

What is compactMapValues { $0 } ? compactMapValues {} can be really helps when we are dealing with optional values inside a dictionary. Readability is also important, especially amongs the developers. compactMapValues is one of the great language feature of Swift. "Returns a new dictionary containing only the key-value pairs that have non-nil values as the … Continue reading Get Rid of `nil` Values using Dictionary.compactMapValues { $0 }
