Question

Suppose my client doesn’t want me to own his iPhone Distribution Certificate, is there a way I can send him the compiled app and let him adjust all App Id, Provisioning etc parameters, then sign and submit it? How do I do this?

Answer 1

Look at the CodeSign step in the XCode build results window (click on the “lines of text” disclosure icon on the right to see the actual commands that XCode uses).

You’ll see that the CodeSign step is using a command-line tool (/usr/bin/codesign) something like this:

/usr/bin/codesign -f -s "iPhone Distribution: My Company" 
    --resource-rules=/Users/username/source/myApp/build/Distribution-iphoneos/myApp.app/ResourceRules.plist 
    --entitlements /Users/username/source/myApp/build/myApp.build/Distribution-iphoneos/myApp.build/myApp.xcent 
    /Users/username/source/myApp/build/Distribution-iphoneos/myApp.app 

It’s signing the compiled application in the “build” directory using the signing identity specified by the “-s” option on the command line. So, there’s no reason you couldn’t move your “build” directory to another machine and sign it with the desired key using codesign from the command line.
