How to use fastlane pem to automatically generate and renew your VoIP push notification profiles

In the previous tutorial, I showed you how easy it is to use fastlane pem to automatically generate and renew your push notification profiles.

In this tutorial, I'll do the same thing, but for VoIP notifications. I found the solution in this Github issue.

In your project's root folder create a new folder called fastlane.

Then, create a file called Fastfile in the fastlane folder.

Put the following content into Fastfile:

lane :voip_cert do
    app_identifier = "com.nikola.mygreatapp"
    apple_id = "[email protected]"
    output_path = "."
    p12_password = "password"

    UI.important "Creating a new push certificate for app '#{app_identifier}'."

    Spaceship.login(apple_id)
    Spaceship.client.select_team
    csr, pkey = Spaceship::Certificate.create_certificate_signing_request
    cert = Spaceship::Certificate::VoipPush.create!(csr:csr,bundle_id:app_identifier)

    x509_certificate = cert.download
    certificate_type = "voippush"
    filename_base = "#{certificate_type}_#{app_identifier}"

    p12_cert_path = File.join(output_path, "#{filename_base}.p12")
    p12 = OpenSSL::PKCS12.create(p12_password, certificate_type, pkey, x509_certificate)
    File.write(p12_cert_path, p12.to_der)
    UI.message("p12 certificate: ".green + Pathname.new(p12_cert_path).realpath.to_s)

    x509_cert_path = File.join(output_path, "#{filename_base}.pem")
    File.write(x509_cert_path, x509_certificate.to_pem + pkey.to_pem)
    UI.message("PEM: ".green + Pathname.new(x509_cert_path).realpath.to_s)
end

Make sure you enter the appropriate app_identifier and apple_id and password (if you're using it).

Execute the following command from your app's root directory:

fastlane voip_cert

You should see something like this in the output:

nikola in ~/DEV/TheOnlyAppThatMatters on git:feature/make-app-great-again ✖︎ [06:06:06]
→ fastlane voip_cert
[06:06:06]: Get started using a Gemfile for fastlane https://docs.fastlane.tools/getting-started/ios/setup/#use-a-gemfile
[06:06:06]: Driving the lane 'voip_cert' ?

[06:06:06]: PEM: /Users/nikola/DEV/TheOnlyAppThatMatters/fastlane/voippush_com.nikola.mygreatapp.pem
[06:06:06]: fastlane.tools finished successfully ?

And that's it! Hope this proves to be helpful for you! ?

How to use fastlane pem to automatically generate and renew your push notification profiles

This is a short tip which will save you a lot of time!

Ever gone through the tedious task of manually creating and maintaining your push notification profiles for your iOS apps? Tutorials like this one were very useful, but nowadays thanks to fastlane pem, you can do it with a single command.

The pem tool creates new .pem, .cer, and .p12 files to be uploaded to your push server if a valid push notification profile is needed.

To install pem run:

sudo gem install fastlane

Also, make sure you have the latest version of the Xcode command line tools installed:

xcode-select --install

Then, just run fastlane pem and it will ask you information about the app for which you wish to renew the certificates.

You can pass parameters like this:

fastlane pem -a com.mygreat.app -u username

If you want to generate a development certificate run:

fastlane pem --development

To get a list of available options run:

fastlane pem --help

?

If you're looking to generate the same thing but for VoIP push notification, then check out this tutorial.
