IDE to develop native Swift, Objective-C, Objective-C++, C and C++ iOS apps and tools on unjailbroken iOS

Nyxian is an iOS app that empowers developers with a full toolchain they can use while even being offline for iOS development on iPhone. It supports Swift, C, Objective-C, C++ and Objective-C++. It’s a powerful Xcode alternative that made the impossible possible, a fully on-device iOS IDE that doesn’t even need a cloud and can even be used with airplane mode enabled. It supports officially iOS 16 all the way up to the latest iOS version(iOS/iPadOS 26.5 tested). You can compile and run iOS apps on the go with ease, using the entire iOS 26.4 SDK.
