That is going to be a plist generation issue. Most likely the plist being generated for the code sign project is incorrectly pulling the bundle identifier from the BaseEngine.ini file instead of your projects DefaultEngine.ini.
As a quick fix, you can go in to BaseEngine.ini (Engine/Config) and change the default from com.YourCompany.[PROJECT_NAME] to com.agileperception.[PROJECT_NAME]. This is purely a workaround for the time being until I can figure out why this is generating incorrectly.
I verified that the patch from issue 38006 is in 4.14.0-release, but it didn’t fix the issue! It works if you cherry-pick that patch into 4.13.2, but not in 4.14.0 itself.
I have done everything possible and cant get my Provisions into UE 4.17 on MacOS 10 High . I went into my Xcode 9.2 and all my certificates and provisions are working and syncing with the Developer online account bundle ID. When I go into project settings of Unreal Engine it shows my Developer and Distribution Certificates, but my Provisions are not showing up and I don’t get any green colors on either.
When I try to manually import the adhoc provision for example, the output log says “IPP ERROR: Failed to find plist in .mobileprovisions file” what is this referring too when all certificates and provisions are located in the Project/Build/IOS directory.
I have also scoured the internet and this site and still can’t figure it out. I am still learning and must be missing something in UE 4.17 for this error to occur.
