Prerequisites

XCode7+, cmake 3.2+

Dependencies

• precompiled openssl
• precompiled boost with modules filesystem, program_options, date_time and system
• ios-cmake toolchain from https://github.com/vovasty/ios-cmake.git

Include into project

• add all libraries in lib folder to Project linked frameworks.
• add libc++ and libz libraries from system libraries to Project linked frameworks.
• add path to i2p headers to your Headers search paths

Alternatively you may use swift wrapper https://github.com/vovasty/SwiftyI2P.git
