Duplicate iOS application target, rename it, add new icon and build app from command line (without using Xcode GUI) - ios

Question

I would like to automate the process of adding a new target to my iOS application and write a script which would speed up the whole process. Is there any way to duplicate Xcode iOS application target, then rename it, add new icon specific for this target, change bundle id, app name etc. and finally build the app? I've tried using AppleScript to achieve this, but with no luck.
The workaround I am using now is to create one additional target (using Xcode GUI) and customize it during the build time (every time I want to build the app). The biggest downside of this approach is that targets' configurations are not saved anywhere and the parameters of the target have to be specified for every build of the app. This can lead to unrepeatable builds and other undebuggable issues. That's why I am looking for a method or a tool which would allow me to duplicate and configure new target from command line script

You can use this ruby script to duplicate any target, but you need to install github.com/CocoaPods/Xcodeproj first :
#!/usr/bin/env ruby
require 'rubygems'
require 'xcodeproj'
puts "Project path:"
proj_path = gets
puts "New target name:"
name = gets
puts "New target bundle identifer"
bundleIdentifier = gets
puts "Witch target to clone?"
srcTargetName = gets
name = name.chomp
bundleIdentifier = bundleIdentifier.chomp
proj_path = proj_path.chomp
srcTargetName = srcTargetName.chomp
proj = Xcodeproj::Project.open(proj_path)
src_target = proj.targets.find { |item| item.to_s == srcTargetName }
#proj_path = "/testingTest.xcodeproj"
# create target
target = proj.new_target(src_target.symbol_type, name, src_target.platform_name, src_target.deployment_target)
target.product_name = name
# create scheme
scheme = Xcodeproj::XCScheme.new
scheme.add_build_target(target)
scheme.set_launch_target(target)
scheme.save_as(proj_path, name, shared = true)
# copy build_configurations
target.build_configurations.map do |item|
item.build_settings.update(src_target.build_settings(item.name))
end
target.build_configurations.each do |config|
config.build_settings['PRODUCT_BUNDLE_IDENTIFIER'] = bundleIdentifier
config.build_settings['PRODUCT_NAME'] = "$(TARGET_NAME)"
end
# copy build_phases
phases = src_target.build_phases.reject { |x| x.instance_of? Xcodeproj::Project::Object::PBXShellScriptBuildPhase }.collect(&:class)
phases.each do |klass|
src = src_target.build_phases.find { |x| x.instance_of? klass }
dst = target.build_phases.find { |x| x.instance_of? klass }
unless dst
dst ||= proj.new(klass)
target.build_phases << dst
end
dst.files.map { |x| x.remove_from_project }
src.files.each do |f|
file_ref = proj.new(Xcodeproj::Project::Object::PBXFileReference)
file_ref.name = f.file_ref.name
file_ref.path = f.file_ref.path
file_ref.source_tree = f.file_ref.source_tree
file_ref.last_known_file_type = f.file_ref.last_known_file_type
#file_ref.fileEncoding = f.file_ref.fileEncoding
begin
file_ref.move(f.file_ref.parent)
rescue
end
build_file = proj.new(Xcodeproj::Project::Object::PBXBuildFile)
build_file.file_ref = f.file_ref
dst.files << build_file
end
end
# add files
#classes = proj.main_group.groups.find { |x| x.to_s == 'Group' }.groups.find { |x| x.name == 'Classes' }
#sources = target.build_phases.find { |x| x.instance_of? Xcodeproj::Project::Object::PBXSourcesBuildPhase }
#file_ref = classes.new_file('test.m')
#build_file = proj.new(Xcodeproj::Project::Object::PBXBuildFile)
#build_file.file_ref = file_ref
#sources.files << build_file
proj.save
