Hi igor

this is strange I have a dictionary whose array contains nil  and still 
isHealthy returns true.
can an array of a dictionary contains nil?

no, it can't .
And how you end up with dictionary which having array = nil? During
initialization, it allocates and initializes array,
so, normally, there is no way how it could be nil.
Ehm, the array can _contain_ nil(the empty slot marker) (and it will in all cases, if it's working correctly), it cannot _be_ nil though.

isHealthy has nothing to do with this though, it checks if all elements (non-nil entries in the array) are at positions which are valid.

Henry
