Foreach Access Violation

[nobody]

Say I have a class Apple:

class Apple
{
    ..
}

Several apples are created:

Apple[] apples;

for(int i = 0; i < 10; i++)
{
    apples.length = apples.length + 1;
    apples[apples.length-1] = new Apple();
}

Then I iterate over all the apples with a foreach loop

foreach(int i, Apple apple; apples)
{
     apples.iterate();
}

And in the iterate() some or more apples delete themselves via

void die()
{
    for (int i = 0; i < apples.length; i++)
    {
         if (apples[i] is this)
        {
            apples[i] = apples[$-1];
            apples.length = apples.length - 1;
            delete this;
        }
    }
}


This generally works fine, except when the last apple is deleted.
Then I get an Access Violation Error in the foreach loop.
When I use a for loop instead it works perfectly.

Is this because the foreach loop doesn't reevalute the length of the apples 
array
while looping, or am I missing something else entirely?
