Some time ago, information security expert Trevor Spiniolas found a nasty bug in HomeKit. It is associated with the lack of restrictions on the number of characters in the name of HomeKit gadgets. According to the expert, if users decide to give a smart speaker, light bulb or any other device a name that is too long (Spiniolas used about 500,000 characters), this will lead to problems with the iPhone and iPad.
At best, the Home app will stop opening. However, if users have added some gadgets to the Control Center, then iOS will stop responding to commands. And restarting does not help solve the problem.
For the first time, a specialist discovered this problem in the summer. On August 10, he sent a report to Apple. The company promised to fix the bug by the end of 2021. However, the problem has not been completely solved so far. Apple representatives say they will return to the issue in early 2022.
In iOS 15.1, the company introduced a character limit for HomeKit device names. But since the name of smart devices is synced via iCloud, the bug can “return” from other devices that are running iOS 15 or iOS 14.7. The expert notes that the error has been present in iOS for a long time.
