简单的for循环

var arr = String[]()
for index in 0..100{
    arr.append("Item(index)")
}
println(arr)

var arr = String[]()

for index in 0..100{

arr.append("Item(index)")

}

println(arr)

遍历数组

for value in arr{
    println(value)
}

for value in arr{

println(value)

}

while循环遍历

var i = 0
while i<arr.count{
    println(arr[i])
    i++
}

var i = 0

while i<arr.count{

println(arr[i])

i++

}

遍历字典

var dict = ["name":"superyyl","age":"16"]
for (key,value) in dict{
    println("(key),(value)")
}
/*
name,superyyl
age,16
*/

var dict = ["name":"superyyl","age":"16"]

for (key,value) in dict{

println("(key),(value)")

}

name,superyyl

age,16
