Directly store value using "if expression" - Swift

When we want to set a variable for a specific condition, this what we normally do:

let temperatureInCelsius = 25
let weatherAdvice: String

if temperatureInCelsius <= 0 {
    weatherAdvice = "It's very cold. Consider wearing a scarf."
} else if temperatureInCelsius >= 30 {
    weatherAdvice = "It's really warm. Don't forget to wear sunscreen."
} else {
    weatherAdvice = "It's not that cold. Wear a T-shirt."
}

print(weatherAdvice)
// Prints "It's not that cold. Wear a T-shirt."
Enter fullscreen mode Exit fullscreen mode

We can make it more cleaner using if expression:

let temperatureInCelsius = 25
let weatherAdvice = if temperatureInCelsius <= 0 {
    "It's very cold. Consider wearing a scarf."
} else if temperatureInCelsius >= 30 {
    "It's really warm. Don't forget to wear sunscreen."
} else {
    "It's not that cold. Wear a T-shirt."
}

print(weatherAdvice)
// Prints "It's not that cold. Wear a T-shirt."
Enter fullscreen mode Exit fullscreen mode
