Bugfixing / Live Support for an Objective C / SWIFT MacOS App

We got an app that we developed and which does not compile anymore. We need someone who can help us via live support: Teamviewer, Skype, Hangrout or any other video chat would be fine. We don't know how much time this needs but please pencil in a day of work. If you finish in 5 minutes, then we're also happy. :-) Here is our problem: I cannot get signatures of the main App and the Helper app right: [login to view URL] We are using SMJobBless to install a helper tool, which doesn't work anymore. Especially, this call doesn't work: success = SMJobBless(kSMDomainSystemLaunchd, (__bridge CFStringRef)([login to view URL]), [login to view URL], &error); I'm pretty sure it's because the certificates are not signed correctly. It is advised to use the Python-script (as referenced in the SO question) to set [login to view URL] file entries, but the same app checking the signatures doesn't find them valid. The signature itself works and is valid, and I can for example start the tool under OS X with Gatekeeper activated and have it execute without warning. Just the helper tool doesn't work, and it's needed in the tool to delete some system files.
