Is there any free IOS/Android exploitation resource?

Hello,i have recently decided to dive into mobile exploit development but could not find any free resources. So i noticed that nearly all of the resources about binary exploitation is focused on Linux and Windows exploitation.What i am searching is not some form of very basic stack based buffer overflow guide with 0 mitigations enabled,i am looking for something that can help me build exploits that can bypass or at least avoid modern day mitigations like Pointer Authentication Codes (PAC).
