I have been working quite some time on version 1.3 of Copper, our Mac EDA application. Check it out if you didn’t know yet. This version brings the ability to import your own STEP models of parts to create wonderful 3D models of your PCB. And this feature also added a lot of (partly external) code to my project.
After archiving the project I wanted to upload it to the App Store. So I went in the Organizer of Xcode, selected the newly created archive and clicked on “Upload to App Store”. But, export failed. I got a strange “Copy failed” error with a hint to some logs. Reading these logs is hard. As I added various Frameworks and external libraries to my application I thought it must have been something to do with that. So, for many months I tried again and again, I ripped my project apart but I never really got this issue solved.
Looking at the logs I noticed that it points out:
