Even though I can successfully test my app on my device, and the build log says that the app was successfully codesigned, I still get the "Codesign verification build after I try to upload my app with application loader" And yes, I use finder to manually compress the binary. The build results include both the embedded mobile provision line, and the Codesign line included in the instructions. Why is applicationloader still telling me that the codesign verificatication failed? For the project setting: I have Code Signing Identity set to "iPhone Distribution" For my target setting for Distribution, both code sign identity and the "any device" are set to my mobile provision which now says iPhone Distribution: My Name. I tried modifying it by looking a tips I found online, such as changing the project setting to iPhone Distribution, and changing the target setting to iPhone distribution instead of iphone developer, but I'm still getting these error messages. Any idea why?
