What kind of crazy stuff did Plaid put in their iOS SDK these days… The SDK binary itself is almost 40MB 🙃

@khaost similar sizes for other big-company SDKs like Google Ads for example. I have a hard time believing that’s all compiled code, but I have never taken the time to analyze it. I would not be surprised if they’ve included image resources or something in .DATA/.RODATA, possibly to 1) avoid exposing them easily to other developers or 2) avoid headaches with NSBundle APIs for accessing them at runtime.

@butternut Plaid SDK also included a separate 4MB resources bundle as part of the framework 😅
