If Else - Swift Programming

if, else if, and else choose one branch based on Boolean conditions.

Choose a branch

if_else.swift

let score = 
var band = "needs practice"

if score >= 90 {
    band = "excellent"
} else if score >= 70 {
    band = "steady"
} else {
    band = "needs practice"
}

print("score=\(score)")
print("band=\(band)")

let score = 
var band = "needs practice"

if score >= 90 {
    band = "excellent"
} else if score >= 70 {
    band = "steady"
} else {
    band = "needs practice"
}

print("score=\(score)")
print("band=\(band)")

let score = 
var band = "needs practice"

if score >= 90 {
    band = "excellent"
} else if score >= 70 {
    band = "steady"
} else {
    band = "needs practice"
}

print("score=\(score)")
print("band=\(band)")

branching An `if` chain tests conditions in order. Swift runs the first branch whose condition is true and skips the rest.
