[swift-evolution] What's the best replacement if "Remove C-style for loops"?

I have several codes like the following:

for var i = 0; i < myarr.count; i += n { // the step is NOT 1
   // many codes

I knew I could use the while loop, but it seems very ugly.
var i = 0
while i < marr.count {
    // some codes

    i += n   // Sometimes it is easy to be missed

If no C-style for loop,  what's the best replacement for it ?
