Swift的Array的for-in+where

這個Array的for in 加上where自己也沒用過，幾乎忘了還可以加上where來過濾，哈哈😅

程式碼很簡單

let numbers = [10,20,30,40,50,60,70,80,90,100]
for n in numbers {
print(n) //印出10~100
}

在for in 後面加上where

let numbers = [10,20,30,40,50,60,70,80,90,100]
for n in numbers where n > 59 {
print(n) //印出60,70,80,90,100
}

實在夠簡單啦!
