xcode: support no preselected profile

[lacostej]

Today we can only update a profile instead of automatically one it it isn't properly selected. It should be possible to select a profile automatically instead.

There are a few problems to solve:

1. I ve failed to implement a working command line pbxproj editor properly using plistBuddy and I am currently using sed

        echo "INFO Replacing ${current_pp_uuid} with ${new_pp_uuid} in $file"
        # this doesn't work as it converts the file into XML and we lose the comments
        # echo ./pbxproj_pp_uuid.sh $file "$configuration" set $new_pp_uuid
        sed "s/${current_pp_uuid}/${new_pp_uuid}/"  ${file} > ${file}.new

This should have called something like

        $plistBuddy $file -c "Set objects:${buildConfigurationObjId}:buildSettings:PROVISIONING_PROFILE[sdk=iphoneos*] ${new_uuid}" 2>/dev/null

but didn't work in my tests. At least, it converted the file to XML and I wanted to keep the original format in order to ensure the config wasn't changed elsewhere.

You can test this using something like

./pbxproj_pp_uuid.sh project.pbxproj 'Ad Hoc' set 9274AB2A-6F96-4BFF-B320-------------

Now XCode may still be able to read XML so this is perhaps not such a big problem.

But for the selection to work, one needs to modify more than just the value of the PROVISIONING_PROFILE.

These are the changes in the project file when I manually go from the default selection to a particular PP:

So we would also need to modify the CODE_SIGN_IDENTITY. This isn't hard in itself, but today I am not managing certificate at all in neither the apple_dev_center.rb script nor the xcode related ruby & bash scripts.

https://github.com/quadion/iOSValidation is an interesting thing to look at for certificate management
