NaughtyKeyboard, an iOS custom keyboard to test your apps

In plain words

NaughtyKeyboard is a custom iOS keyboard designed for app developers and testers. It allows users to input unusual characters, edge cases, and problematic data that standard keyboards cannot easily produce, helping identify how applications handle unexpected input. The keyboard was launched in 2015 and is available as an open-source project on GitHub, making it accessible to developers who need to stress-test their applications with unconventional text and special characters.
