Ok I realised what my problem was. It was casting the data to (char*). I did this as that's the type I needed the data in. But strlen and other things will stop at the first null byte so it seemed like I was only receiving a little bit of the data. It will also read passed the end of the context when casting the data bytes to char*, then you get that data again on the next receive which is also an issue. I'm still confused however why is_complete isn't coming back as true, so it sits on the next receive forever

I had the same issue, although there didn't seem to be any way to set the fork in Xcode as like you say it seems to stubornly set it to the original repo I did have success editing the project file in a text editor: {project}.xcodeproj/project.pbxproj and update the repositoryURL there That prompted Xcode to fetch the dependencies again, this time of the fork
