For 문

  1. 특정 범위 지정

for term in 1...10 {

    println("my term \(term)")

}

var someArray = [1,2,3,4,5]

for term in 1...someArray.count {

    println("my term \(term)")

}

  2. 배열 탐색

var someArray = [1,2,3,4,5]

for term in someArray {

    println("my term \(term)")

} 

  3. 증가값 지정

for var term = 0; term < 10; term++ {

    println("my term \(term)")

}

  4. 문자열도 됨

var traceString = "tracing."

for tracer in traceString {

    println("trace : \(tracer)");

}
