I have an IPA file exported for development and I want to sign the IPA file using a valid enterprise certificate. Actually, I have gone through all the steps mentioned here amd here and used various available tools such as ota-tools and iResign to sign the file.
The app is actually a very small swift app and only uses app groups and key-chain sharing capabilities and is developed by members of my enterprise team using the App ID and team identifier that we have defined using Xcode in our enterprise account.
I have done the resigning process without any problem and the app is installed successfully on my iPhone. But it immediately crashes upon startup.
So, I doubted the resigning process and did some checks. I tried to check the resigned IPA file using 'codesign -v' command but it says "code object is not signed at all".
I also unzipped the IPA file did all the code-signing on the main app and Frameworks folder but still head no luck with codesign verification. it still says "code object is not signed at all".
I would appreciate if someone can help me with this problem.
