Obj c for loop showing out of scope on variable

I am trying to write a for loop in Obj-c and getting 'out of scope' on my var

for ( myObject *i in blah ) {
 i.somevar  开发者_Python百科<--- i showing out of scope in debug mode.
}

myObject should be MyObject; class names are capitalized in Objective-C.

If you are building for Release, the optimizer is on and it could easily be optimizing away i.
