How to patch a ipa file

1. Download a cracked ipa. (eg. https://www.iphonecake.com)
2. Use Xcode to create an iOS Dynamic Framework (see below as an example). Build the framework target for iphoneos (non-iphonesimulator)
3. Reveal the framework in finder and locate the dynamic library binary.
4. Copy the entire framework (or just dynamic library binary file will do) and any depedent dylibs into a folder (lets call it DYLIBS).
5. You may need additional XCode stock swift dylib which you can find them at /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift. Copy any required swift dylib into the DYLIBS folder
6. Go to the root level of this repository and run sh ./patchapp.sh cracked.ipa ./DYLIBS
7. You will see an output file called "cracked-patch.ipa". Use Cydia Impactor (http://www.cydiaimpactor.com) to sign the new and install it into your device.
