That sounds frightening, but the presence of a cyanide-forming compound doesn’t mean accidentally swallowing an apple seed is automatically dangerous.
The amount matters enormously.
Occasionally swallowing a whole apple seed is generally not a reason to panic. Whole seeds are also less likely to release their contents because their outer coating can pass through the digestive system relatively intact.

The pit itself is hard and is not normally eaten.
