In each half hour consultation, Cocoa engineers are available to help you with just about anything related to product development. This includes technical software reviews. That said, software issues can be massively complex and we cannot guarantee any solution in just a 30 minute consultation.
To most efficiently provide code reviews in a consultation, we recommend you upload your code when scheduling as shown below. Please try to include as many details as possible like any errors you're receiving, language it's coded in, how you're compiling, hardware you're using, or anything else you think is important.
