I’m happy to announce the supply of Fastlane in your AWS CodeBuild for macOS environments. AWS CodeBuild is a totally managed steady integration service that compiles supply code, runs assessments, and produces ready-to-deploy software program packages.
Fastlane is an open supply device suite designed to automate numerous facets of cellular software growth. It gives cellular software builders with a centralized set of instruments to handle duties akin to code signing, screenshot era, beta distribution, and app retailer submissions. It integrates with common steady integration and steady deployment (CI/CD) platforms and helps each iOS and Android growth workflows. Though Fastlane affords vital automation capabilities, builders might encounter challenges throughout its setup and upkeep. Configuring Fastlane could be complicated, notably for groups unfamiliar with the syntax and package deal administration system of Ruby. Holding Fastlane and its dependencies updated requires ongoing effort, as a result of updates to cellular platforms or third-party companies might necessitate changes to current workflows.
When we launched CodeBuild for macOS in August 2024, we knew that certainly one of your challenges was to put in and keep Fastlane in your construct atmosphere. Though it was attainable to manually set up Fastlane in a customized construct atmosphere, at AWS, we take away the undifferentiated heaving lifting out of your infrastructure so you may spend extra time on the facets that matter for what you are promoting. Beginning in the present day, Fastlane is put in by default, and you should use the acquainted command fastlane constructin your buildspec.yaml file.
Fastlane and code signing
To distribute an software on the App Retailer, builders should signal their binary with a non-public key generated on the Apple Developer portal. This non-public key, together with the certificates that validates it, should be accessible throughout the construct course of. This generally is a problem for growth groups as a result of they should share the event non-public key (which permits deployment on chosen check units) amongst group members. Moreover, the distribution non-public key (which allows publishing on the App Retailer) should be obtainable throughout the signing course of earlier than importing the binary to the App Retailer.
Fastlane is a flexible construct system in that it additionally helps builders with the administration of growth and distribution keys and certificates. Builders can use fastlane match to share signing supplies in a group and make them securely and simply accessible on particular person builders’ machines and on the CI atmosphere. match permits the storage of personal keys, the certificates, and the cellular provisioning profiles on a secured share storage. It makes certain that the native construct atmosphere, whether or not it’s a developer laptop computer or a server machine within the cloud, stays in sync with the shared storage. At construct time, it securely downloads the required certificates to signal your app and configures the construct machine to permit the codesign utility to select them up.
match permits the sharing of signing secrets and techniques by GitHub, GitLab, Google Cloud Storage, Azure DevOps, and Amazon Easy Storage Service (Amazon S3).
When you already use certainly one of these and also you’re migrating your tasks to CodeBuild, you don’t have a lot to do. You solely want to verify your CodeBuild construct atmosphere has entry to the shared storage (see step 3 within the demo).
Let’s see the way it works
When you’re new to Fastlane or CodeBuild, let’s see the way it works.
For this demo, I begin with an current iOS venture. The venture is already configured to be constructed on CodeBuild. You’ll be able to discuss with my earlier weblog submit, Add macOS to your steady integration pipelines with AWS CodeBuild, to study extra particulars.
I’ll present you the right way to get began in three steps:
- Import your current signing supplies to a shared non-public GitHub repository
- Configure
fastlaneto construct and signal your venture - Use
fastlanewith CodeBuild
Step 1: Import your signing supplies
Many of the fastlane documentation I learn explains the right way to create a brand new key pair and a brand new certificates to get began. Though that is actually true for brand spanking new tasks, in actual life, you in all probability have already got your venture and your signing keys. So, step one is to import these current signing supplies.
Apple App Retailer makes use of completely different keys and certificates for growth and distribution (there are additionally advert hoc and enterprise certificates, however these are outdoors the scope of this submit). It’s essential to have three recordsdata for every utilization (that’s a complete of six recordsdata):
- A
.mobileprovisionfile that you may create and obtain from the Apple developer console. The provisioning profile hyperlinks your identification, the app identification, and the entitlements the app may need. - A
.cerfile, which is the certificates emitted by Apple to validate your non-public key. You’ll be able to obtain this from the Apple Developer portal. Choose the certificates, then choose Obtain. - A
.p12file, which comprises your non-public key. You’ll be able to obtain the important thing while you create it within the Apple Developer portal. When you didn’t obtain it however have it in your machine, you may export it from the Apple Keychain app. Be aware that the KeyChain.app is hidden in macOS 15.x. You’ll be able to open it withopen /System/Library/CoreServices/Functions/Keychain Entry.app. Choose the important thing you need to export and proper click on to pick Export.
![]() |
![]() |
When you’ve these recordsdata, create a fastlane/Matchfile file with the next content material:
git_url("https://github.com/sebsto/secret.git")
storage_mode("git")
sort("growth")
# or use appstore to make use of the distribution signing key and certificates
# sort("appstore")
Be sure you exchange the URL of your GitHub repository and ensure that this repository is non-public. It’ll function a storage in your signing key and certificates.
Then, I import my current recordsdata with the fastlane match import --type appstore command. I repeat the command for every atmosphere: appstore and growth.
The very first time, fastlane prompts me for my Apple Id username and password. It connects to App Retailer Hook up with confirm the validity of the certificates or to create new ones when crucial. The session cookie is saved in ~/.fastlane/spaceship/<your apple consumer id>/cookie.
fastlane match additionally asks for a password. It makes use of this password to generate a key to crypt the signing supplies on the storage. Don’t neglect this password as a result of will probably be used at construct time to import the signing supplies on the construct machine.
Right here is the command and its output in full:
fastlane match import --type appstore

Step 2: Configure Fastlane to signal your venture
I create a Fastlane construct configuration file in fastlane/Fastfile (you should use fastlane init command to get began):
default_platform(:ios)
platform :ios do
before_all do
setup_ci
finish
desc "Construct and Signal the binary"
lane :construct do
match(sort: "appstore", readonly: true)
gymnasium(
scheme: "getting began",
export_method: "app-store"
)
finish
finish
Ensure that the setup_ci motion is added to the before_all part of Fastfile for the match motion to operate accurately. This motion creates a short lived Fastlane keychain with right permissions. With out this step, you might encounter construct failures or inconsistent outcomes.
And I check an area construct with the command fastlane construct. I enter the password I used when importing my keys and certificates, then I let the system construct and signal my venture. When the whole lot is accurately configured, it produces an identical output.

[17:58:33]: fastlane.instruments completed efficiently 🎉
Step 3: Configure CodeBuild to make use of Fastlane
Subsequent, I create a venture on CodeBuild. I’m not going into the step-by-step information that can assist you to take action. You’ll be able to discuss with my earlier submit or to the CodeBuild documentation.
There is only one Fastlane-specific configuration. To entry the signing supplies, Fastlane requires entry to 3 secret values that I’ll move as atmosphere variables:
MATCH_PASSWORD, the password I entered when importing the signing materials. Fastlane makes use of this password to decipher the encrypted recordsdata within the GitHub repositoryFASTLANE_SESSION, the worth of the Apple Id session cookie, positioned at~/.fastlane/spaceship/<your apple consumer id>/cookie. The session is legitimate from a few hours to a number of days. When the session expires, reauthenticate with the commandfastlane spaceauthout of your laptop computer and replace the worth ofFASTLANE_SESSIONwith the brand new worth of the cookie.MATCH_GIT_BASIC_AUTHORIZATION, a base 64 encoding of your GitHub username, adopted by a colon, adopted by a private authentication token (PAT) to entry your non-public GitHub repository. You’ll be able to generate PAT on the GitHub console in Your Profile > Settings > Builders Settings > Private Entry Token. I exploit this command to generate the worth of this atmosphere variable:echo -n my_git_username:my_git_pat | base64.
Be aware that for every of those three values, I can enter the Amazon Useful resource Title (ARN) of the key on AWS Secrets and techniques Supervisor or the plain textual content worth. We strongly suggest utilizing Secrets and techniques Supervisor to retailer security-sensitive values.
I’m a security-conscious consumer, so I retailer the three secrets and techniques in Secrets and techniques Supervisor with these instructions:
aws --region $REGION secretsmanager create-secret --name /CodeBuild/MATCH_PASSWORD --secret-string MySuperSecretPassword
aws --region $REGION secretsmanager create-secret --name /CodeBuild/FASTLANE_SESSION --secret-string $(cat ~/.fastlane/spaceship/my_appleid_username/cookie)
aws --region $REGION secretsmanager create-secret --name /CodeBuild/MATCH_GIT_BASIC_AUTHORIZATION --secret-string $(echo -n my_git_username:my_git_pat | base64)
In case your construct venture refers to secrets and techniques saved in Secrets and techniques Supervisor, the construct venture’s service position should permit the secretsmanager:GetSecretValue motion. When you selected New service position while you created your venture, CodeBuild contains this motion within the default service position in your construct venture. Nonetheless, in case you selected Current service position, you should embody this motion to your service position individually.
For this demo, I exploit this AWS Identification and Entry Administration (IAM) coverage:
{
"Model": "2012-10-17",
"Assertion": [
{
"Effect": "Allow",
"Action": [
"secretsmanager:GetSecretValue"
],
"Useful resource": [
"arn:aws:secretsmanager:us-east-2:012345678912:secret:/CodeBuild/*"
]
}
]
}
After I created the venture within the CodeBuild part of the AWS Administration Console, I enter the three atmosphere variables. Discover that the worth is the title of the key in Secrets and techniques Supervisor.
You can too outline the atmosphere variables and their Secrets and techniques Supervisor secret title in your buildpsec.yaml file.
Subsequent, I modify the buildspec.yaml file on the root of my venture to make use of fastlane to construct and signal the binary. My buildspec.yaml file now appears to be like like this one:
# buildspec.yml
model: 0.2
phases:
set up:
instructions:
- code/ci_actions/00_install_rosetta.sh
pre_build:
instructions:
- code/ci_actions/02_amplify.sh
construct:
instructions:
- (cd code && fastlane construct)
artifacts:
title: getting-started-$(date +%Y-%m-%d).ipa
recordsdata:
- 'getting began.ipa'
base-directory: 'code'
The Rosetta and Amplify scripts are required to obtain the Amplify configuration for the backend. When you don’t use AWS Amplify in your venture, you don’t want these.
Discover that there’s nothing within the construct file that downloads the signing key or prepares the keychain within the construct atmosphere; fastlane match will try this for me.
I add the brand new buildspec.yaml file and my ./fastlane listing to Git. I commit and push these recordsdata. git commit -m "add fastlane assist" && git push
When the whole lot goes properly, I can see the construct operating on CodeBuild and the Succeeded message.
Pricing and availability
Fastlane is now pre-installed at no further value on all macOS photos that CodeBuild makes use of, in all Areas the place CodeBuild for macOS is on the market. On the time of this writing, these are US East (Ohio, N. Virginia), US West (Oregon), Asia Pacific (Sydney), and Europe (Frankfurt).
In my expertise, it takes a little bit of time to configure fastlane match accurately. When it’s configured, having it engaged on CodeBuild is fairly easy. Earlier than attempting this on CodeBuild, make certain it really works in your native machine. When one thing goes incorrect on CodeBuild, triple-check the values of the atmosphere variables and ensure CodeBuild has entry to your secrets and techniques on AWS Secrets and techniques Supervisor.
Now go construct (on macOS)!
