Swift If (Real-Life Examples)

Swift If (Real-Life Examples)

Apply conditional logic to real situations like validation, feature flags, or permissions.

---

Validate input with conditions

Use conditions to validate input and guard against empty or invalid values.

Example

let input = "hello"
if !input.isEmpty {
  print("Input received: \(input)")
}

When the input is empty, the code inside the condition is skipped.

Feature Flag

Gate a feature behind a flag and a user group.

Example

let enabled = true
let userGroup = "beta"
if enabled && userGroup == "beta" {
  print("Show feature")
}
