BetaBuilder, a gem for managing iOS ad-hoc builds

BetaBuilder is a simple collection of Rake tasks and utilities for managing and publishing Adhoc builds of your iOS apps.

If you're looking for the OSX BetaBuilder app -- to which this gem owes most of the credit -- you can find it here on Github.

Note: As of release 0.7, support for Xcode 3 is deprecated. Xcode 4 has been out for a year, has got much more stable as of 4.1 on Lion (or 4.2 if you've been using the betas) and it's time to move on. Generating Xcode 4 friendly archives and builds in this release still needs a bit of configuration but will become much smoother in 0.8 once Xcode 3 support is removed.

Motivation

The problem with using a GUI app to create the beta packages is that it is yet another manual step in the process of producing an ad-hoc build for your beta testers. It simplifies some steps but it still requires running Build and Archive in Xcode, saving the resulting build as an IPA package, running the Beta Builder app, locating the IPA, filling in the rest of the fields and generating the deployment files. Then you need to upload those files somewhere.

As a Ruby developer, I use Rake in most of my projects to run repetitive, often build or test-related tasks and it's equally as useful for non-Ruby projects as it is for Ruby ones.

This simple task library allows you to configure once and then build, package and distribute your ad-hoc releases with a single command.

Usage

To get started, if you don't already have a Rakefile in the root of your project, create one. If you aren't familiar with Rake, it might be worth going over some of the basics but it's fairly straightforward.

You can install the BetaBuilder gem from your terminal (OSX 10.6 ships with a perfectly useful Ruby installation):

$ gem install betabuilder

At the top of your Rakefile, you'll need to require rubygems and the betabuilder gem (obviously).

require 'rubygems'
require 'betabuilder'

Because BetaBuilder is a Rake task library, you do not need to define any tasks yourself. You simply need to configure BetaBuilder with some basic information about your project and it will generate the tasks for you. A sample configuration might look something like this:

BetaBuilder::Tasks.new do |config|
  # your Xcode target name
  config.target = "MyGreatApp"

  # the Xcode configuration profile
  config.configuration = "Adhoc" 
end

Now, if you run rake -T in Terminal.app in the root of your project, the available tasks will be printed with a brief description of each one:

rake beta:build     # Build the beta release of the app
rake beta:package   # Package the beta release as an IPA file

If you use a custom Xcode build directory, rather than the default ${SRCROOT}/build location, you can configure that too:

BetaBuilder::Tasks.new do |config|
  ...
  config.build_dir = "/path/to/custom/build/dir"
end

To deploy your beta to your testers, some additional configuration is needed (see the next section).

Most of the time, you'll not need to run the beta:build task directly; it will be run automatically as a dependency of beta:package. Upon running this task, your ad-hoc build will be packaged into an IPA file and will be saved in ${PROJECT_ROOT}/pkg/dist, along with a HTML index file and the manifest file needed for over-the-air installation.

If you are not using the automatic deployment task, you will need to upload the contents of the pkg/dist directory to your server.

To use a namespace other than "beta" for the generated tasks, simply pass in your chosen namespace to BetaBuilder::Tasks.new:

BetaBuilder::Tasks.new(:my_custom_namespace) do |config|
end

This lets you set up different sets of BetaBuilder tasks for different configurations in the same Rakefile (e.g. a production and staging build).

Configuration

A full list of configuration options and their details

configuration - (String) The Xcode Configuration to use (Defined on the Info tab of the Project)

build_dir - (File Path) The directory the build output will be. (:derived for Xcode 4 for versions < 0.8)

auto_archive - (true/false) Automatically archive when packaging

archive_path - (File Path) Path to the Archives

xcodebuild_path - (File Path) Path to xcodebuild, if its non-standard

xcodeargs - (Arguments) Arguments passed to xcodebuild when it runs

project_file_path - (File Path) Path to the .xcodeproj file

workspace_path - (File Path) Path to the .xcworkspace file

ipa_destination_path - (File Path) Path to output Packaged IPA to

scheme - (String) What Scheme to use when building

app_name - (String) The name of the app being built (should match the file name, less the .app extension)

arch - (String) The architecture to build for, if different from project settings

xcode4_archive_mode - (true/false) Use Xcode4's Archive mode

skip_clean - (true/false) Skip the clean step when building

verbose - (true/false) Increased output for debugging

dry_run - (true/false) Don't upload to Distribution Strategy, just act like it

set_version_number - (true/false) Attempts to set a version number, see below

Configuration (Testflight)

Testflight presents its own set of options that can be configured

api_token - (String) Can be your API key, but its recommended to use an ENV[""] variable

team_token - (String) Your Team's Testflight API token

distribution_lists - (Array) A Ruby array ([1,2] or %w{1 2}) of distribution list names for Testflight

notify - (true/false) Notify the distribution list of this build

replace - (true/false) Replace if an existing build exists with the same ID and version

Configuration (Web)

Pushing to a web server has the following options.

SSH keys will simplify authentication and make this process seamless

remote_host - (String) Hostname for the server the build will be pushed to

remote_port - (String) Port Number to use for SCP/SFTP

remote_installation_path - (String) Remote Path

Configuration (RunTime)

Certain configuration options are availabe at the command line, so that you can temporarily set them for a single run without modifying your configuration.

Pass any of these in as environment variables:

DRY - (true/false) Enable Dry Run VERBOSE - (true/false) Turn on all output; lets you see the clean, build, and signing output SKIPCLEAN - (true/false) Skips the clean step and goes right to Build.

####Examples

rake staging:deploy DRY=true

rake staging:redeploy VERBOSE=true SKIPCLEAN=true

Xcode 4 support

Betabuilder works with Xcode 4, but you may need to tweak your task configuration slightly. The most important change you will need to make is the build directory location, unless you have configured Xcode 4 to use the "build" directory relative to your project, as in Xcode 3.

If you are using the Xcode derived data directory for your builds, then you will need to specify this. Betabuilder will then scan your build log to determine the path to the automatically generated build directory that Xcode is using for your project.

config.build_dir = :derived

This will become the default in 0.8.

If you wish to generate archives for your Xcode 4 project, you will need to enable this. This will become the default in future once Xcode 3 support is dropped (deprecated in 0.7):

config.xcode4_archive_mode = true

If you are working with an Xcode 4 workspace instead of a project file, you will need to configure this too:

config.workspace_path = "MyWorkspace.xcworkspace"
config.scheme         = "My App Scheme"
config.app_name       = "MyApp"
set_version_number

If you are using a workspace, then you must specify the scheme. You can still specify the build configuration (e.g. Release).

Automatic deployment with deployment strategies

BetaBuilder allows you to deploy your built package using it's extensible deployment strategy system; the gem currently comes with support for simple web-based deployment or uploading to TestFlightApp.com. Eventually, you will be able to write your own custom deployment strategies if neither of these are suitable for your needs.

Setting version numbers automatically

You can use betabuilder to set a build number using Git's describe system. In order for that to work, at least one tag must exist somewhere in the git hierarchy for the branch being built from.

Also, you are required to set your CFBundleVersion to ${VERSION_LONG} inside your Info.plist. To accomodate manual builds, add a VERSION_LONG Build Setting to your app's Project, and treat it as you normally would your Info.plist version number.

Once a tag is created and your App is configured, simply add this to your BetaBuilder config and it will use Git to generate the

config.set_version_number = true

It will generate a version number like: 1.0-15-g6b3c1bb.

  • 1.0 is the most recent tag
  • 15 is the number of commits since the tag was generated
  • g6b3c1bb is the beginning of the hash of the last commit.

Deploying your app with TestFlight

By far the easiest way to get your beta release into the hands of your testers is using the excellent TestFlight service, although at the time of writing it is still in private beta. You can use TestFlight to manage your beta testers and notify them of new releases instantly.

TestFlight provides an upload API and betabuilder uses that to provide a :testflight upload strategy. This strategy requires two pieces of information: your TestFlight API token and your team token:

config.deploy_using(:testflight) do |tf|
  tf.api_token  = "YOUR_API_TOKEN"
  tf.team_token = "YOUR_TEAM_TOKEN"
end

Now, instead of using the beta:package task, you can run the beta:deploy task instead. This task will run the package task as a dependency and upload the generated IPA file to TestFlight.

You will be prompted to enter the release notes for the build; TestFlight requires these to inform your testers of what has changed in this build. Alternatively, if you have a way of generating the release notes automatically (for instance, using a CHANGELOG file or a git log command), you can specify a block that will be called at runtime - you can do whatever you want in this block, as long as you return a string which will be used as the release notes, e.g.

config.deploy_using(:testflight) do |tf|
  ...
  tf.generate_release_notes do
    # return release notes here
  end
end

Finally, you can also specify an array of distribution lists that you want to allow access to the build:

config.deploy_using(:testflight) do |tf|
  ...
  tf.distribution_lists = %w{Testers Internal}
end

Deploying to your own server

BetaBuilder also comes with a rather rudimentary web-based deployment task that uses SCP, so you will need SSH access to your server and appropriate permissions to use it. This works in the same way as the original iOS-BetaBuilder GUI app by generating a HTML template and manifest file that can be uploaded to a directly on your server. It includes links to install the app automatically on the device or download the IPA file.

You will to configure betabuilder to use the web deployment strategy with some additional configuration:

config.deploy_using(:web) do |web|
  web.deploy_to = "http://beta.myserver.co.uk/myapp"
  web.remote_host = "myserver.com"
  web.remote_directory = "/remote/path/to/deployment/directory"
end

The deploy_to setting specifies the URL that your app will be published to. The remote_host setting is the SSH host that will be used to copy the files to your server using SCP. Finally, the remote_directory setting is the path to the location to your server that files will be uploaded to. You will need to configure any virtual hosts on your server to make this work.
