"The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate." Does this message sound familiar to any of you? My application is ready to go, I've done all the artwork and screenshots and filled in all the details. But I have so far spent 8 hours and counting trying to upload the binary. I've followed the instructions on the developer portal to the letter and I've tried several things that google searches have brought up. It seems I'm not alone in getting this damn thing to work. When I check Xcode, I have the correct distribution certificates and provisioning profiles set. The build succeeds and the build results show the correct locations. Even when I type codesign into Terminal, it says: app: valid on disk app: satisfies its Designated Requirement I've double checked the Icon.png is 57x57 etc. And yet I get the dreaded "binary is invalid" message every time I upload. Even the application loader fails at the beginning, saying "Application failed codesign verification" Anyone got any ideas? After all this time, I'm keen on getting my app out there but obviously Apple's codesigning requires a rocket science degree and I'm falling desperately at the final hurdle!! Any help would be greatly appreciated!!!
