Questions tagged [cydia-substrate]

Cydia Substrate is a framework that allows third party developers to provide run-time patches to system functions on mobile devices.

Cydia Substrate (formerly Mobile Substrate) is a framework developed by SaurikIT, LLC that allows third party developers to provide run-time patches to system functions on mobile devices. ON iOS devices, it also allows third party developers to hook non-system functions, e.g., objective C or swift methods, and replace them with alternative logic. It may be used in conjunction with frameworks like Theos (on iOS devices) for easier syntax, compiling, packaging and distribution.

Cydia Substrate is currently supported on jailbroken iOS and rooted Android devices.
