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")
}
