I am new to iOS. I was installing latest XCode with SDK 6.0 in it. I have been successfully testing my app developed using SDK 6.0 on simulator. Now i want to test it on real device without developer program account. To do that, i use Jailcoder. I have an iPhone 3GS, with AppSync 5.0+ installed. I have tried "Quick XCode Patch" and "Patch My Project". However i still get signing error. It said,
CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 6.0'
Seems it due to iOS 6.0 SDK that has not been supporting jailbroken devices. I need some hints and workarounds to deal with this error.
By default, Xcode requires iOS apps to be signed. However, there is a plist file that Xcode uses, where you can change this. You can tell Xcode that code signing is not required.
Check this file:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/SDKSettings.plist
You can edit it on your Mac with the Property List Editor application.
Make sure that in that file, CODE_SIGNING_REQUIRED is set to NO. You'll probably need to do this each time you install a new iOS SDK (e.g. 5.0, 5.1, 6.0, etc.)
You can find out more about this on the BigBoss website here. BigBoss is one of the popular Cydia repositories for distributing jailbreak apps and tweaks.
