99 Bottles of Beer in Swift Language

99BottlesOfBeer.swift

var i = 99
while i > 0
    println(i + " bottles of beer on the wall, " + i + "bottles of beer.")
    var num = i - 1
    if i == 1 {
      var num = "no more"
    }
    println("Take one down and pass it around, " + num + "bottles of beer on the wall.")
println("No more bottles of beer on the wall, no more bottles of beer.")
println("Go to the store and buy some more, 99 bottles of beer on the wall.")

Try this instead.

for i in reverse(1...99) {
println("(i) bottles of beer on the wall, (i) bottles of beer.")
var num = toString(i - 1)
if ( i == 1 ) { num = "no" }
println("Take one down and pass it around, (num) bottles of beer on the wall.")
}
println("No more bottles of beer on the wall, no more bottles of beer.")
println("Go to the store and buy some more, 99 bottles of beer on the wall.")

Swift 5:

for i in (1...99).reversed() {
    print("\(i) bottles of beer on the wall, \(i) bottles of beer.")
    var num = String(i - 1)
    if ( i == 1 ) { num = "no" }
    print("Take one down and pass it around, \(num) bottles of beer on the wall.")
}
print("No more bottles of beer on the wall, no more bottles of beer.")
print("Go to the store and buy some more, 99 bottles of beer on the wall.")
