Wherever possible, we should prefer to use a single switch statement over multiple if statements. The following example shows the preferred and non-preferred methods:
//Preferred Method let speed = 300_000_000 switch speed { case 300_000_000: print("Speed of light") case 340: print("Speed of sound") default: print("Unknown speed") } //Non-preferred Method let speed = 300_000_000 if speed == 300_000_000 { print("Speed of light") } else if speed == 340 { print("Speed of sound") } else { print("Unknown speed") }
