Apple has sent a removal letter to affected developers to inform them that their app does not comply with Section 19.1 of the App Store Review Guidelines.
"19.1 Apps containing references or commentary about a religious, cultural or ethnic group that are defamatory, offensive, mean-spirited or likely to expose the targeted group to harm or violence will be rejected."
MacRumors did a spot check of the App Store and can confirm that Apple has removed dozens of Civil War games depicting the Confederate Flag, which has been at the center of a racial controversy ignited by a Charleston, South Carolina church shooting last week.
Most educational or generic Civil War apps remain available on the App Store.
A sampling of the Civil War games removed from the App Store:
Ultimate General: Gettysburg
AAA American Civil War Cannon Shooter
Civil War: Hidden Mysteries
Civil War The Battle Game
Civil War Defense
Civil War Battle Defense
1861 A Civil War Rebellion
Civil War: 1862
Civil War: 1863
In a statement provided to Buzzfeed, Apple has confirmed that it is removing apps that use the Confederate flag in "offensive or mean-spirited ways."
Apple is also said to be working with game developers to get the affected apps back in the App Store after replacing the Confederate flag.
"We have removed apps from the App Store that use the Confederate flag in offensive or mean-spirited ways, which is in violation of our guidelines,” an Apple spokesperson told BuzzFeed News.
"We are not removing apps that display the Confederate flag for educational or historical uses."
