Ninjawords, a dictionary app was rejected multiple times for containing swear words, even thought it only contained words listed in the dictionary.
The app was approved after developer Matchstick Software removed objectionable four-letter words and it was given a 17+ rating.
Matchstick said the words in question were only able to be found when searched for in their entirety, and were not accessible by scrolling through listings or partially spelling them.
Words such as snatch, screw and micturition (which means ‘to urinate') were also deemed dodgy.
Others to have fallen victim to Apple's app submission process, include The Sun's page 3 girls and an app based on the Karma Sutra.
Last week Apple also rejected Google Voice, claiming it 'duplicated functionality' offered by the iPhone. The rejection has attracted the attention of the US Federal Communications Commission.
Developers are also closely watching the approval process for Spotify's music-streaming iPhone app, which some view as a competitor to Apple's music services.
