问题
I'm currently using an iOS SDK (.framework directory) in my project, and I'm in need of modifying some of its assets.
So far I've been able to locate the file with said assets, called Assets.car in mySDK.framework/mySDKResourceBundle.bundle/Assets.car, and using a tool called Asset Catalog Tinkerer I'm also able to see and extract all of the .car's contents.
Unfortunately I just can't seem to find how to modify the assets inside that file to include my own or, failing this, to create a .car file using my own assets so that the framework can use those instead of the original ones.
Is there a tool that can help me to modify or create from scratch this sort of file?
