Let me guess: does your stack trace (type "tb" in the gdb console)
indicate infinite recursion? Either synthesize accessors or write
your own - but don't try to do both at once. Down that road lies
madness.
This is not correct.
Certainly there is little point in using @synthesize if you're going
to implement both the getter and setter, however it is perfectly
reasonable to use @synthesize and still provide a custom
implementation of one of the methods. The instruction to the compiler
is to synthesize the methods *if it cannot find any other
implementation*.

In the case of the implementations provided here, both of them are
valid and will not result in infinite recursion.
If the implementations had been:
- (int)numberOfSides {
return self.numberOfSides;
}
and/or
- (void)setNumberOfSides:(int)value {
self.numberOfSides = value;
}
then this would have resulted in infinite recursion.
