[Swift-user] two questions about Swift

[Yi Zhu]

Hi all

I have two questions about swift:

1. conventional loop:  In swift, we can use foreach to parallel apps, 
but what If I just need a conventional loop, like a regular "for" or 
"while" in java?

2.  In Matlab, there are some library which support some Math functions 
like "sin" "cos" "reshape" etc. Is there any similar library available 
for swift. If not, is there anyway to import external library? (e.g. 
from Java)

Many Thanks.
