How can we destroy child objects in edit mode(Unity3d)?

Question

It is kind of strange things, but if you'll try to destroy child objects with DestroyImmediate function, then you will have unpredictabe result.

In my case Unity did not destroyed all childs, but did it for only half of them.

        foreach(var child in parent)
        {
            DestroyImmediate(child);
        }

Answer 1

This is how i destroy children in Edit Mode:

for (int i = this.transform.childCount; i > 0; --i)
    DestroyImmediate(this.transform.GetChild(0).gameObject);

Answer 2

As one guy consider in link it is possible with creating temp array/list.

For example:

        var tempArray = new GameObject[parent.transform.childCount];

        for(int i = 0; i < tempArray.Length; i++)
        {
            tempArray[i] = parent.transform.GetChild(i).gameObject;
        }

        foreach(var child in tempArray)
        {
            DestroyImmediate(child);
        }
