In my full-time job, I’m working on a project that was started almost 12 years ago. I have no illusion that I would be able to compile and run this on Xcode for iPad. In my spare time, I’m building a pure SwiftUI App with a few external SwiftPM dependencies, no custom build scripts besides SwiftLint, no interface builder. I don’t see why it wouldn’t be great to work on this on the iPad.

I don’t understand the negative sentiment towards Xcode on iPad. Even comments like: “it will only be used by children to ship their first toy App”. Wouldn’t this be already a great achievement in itself?

I finally finished rewriting my hacky Jekyll micropub endpoints in Rust. Now hosted for free on Heroku and GitHub pages.

If Apple is going to announce the ARM transition soon, maybe we can install macOS on this new iPad? 😁

Internal SwiftPM packages are a game changer for me. It‘s finally as easy as it should be to modularize an App.

A typical post of the category: “Better write a blog post about it, otherwise I will forget how to make it work”
Early on in the development of Icro I integrated fastlane to run continuous integration tests on bitrise and build and uploaded release version from a local Mac. As GitHub Actions is now available and offers similar features as bitrise for open source projects, I decided to move the CI tests over and also start using it for Apple TestFlight deployments.
Thanks to the already defined lanes, the migration to run unit tests on every push and pull request was trivially easy.
The Fastfile just uses the
run_testsaction configured with the correct workspace and scheme:
default_platform(:ios) platform :ios do desc "Run unit tests" lane :tests do run_tests(workspace: "Icro.xcworkspace", derived_data_path: "derivedData", devices: ["iPhone Xs"], scheme: "Icro") end ... end
The GitHub action workflow file defines when the action should be run, installs the bundle dependencies (including fastlane) and runs the lane
name: CI on: [push, pull_request] jobs: build: runs-on: macos-latest steps: - uses: actions/checkout@v1 - name: submodules-init uses: snickerbockers/submodules-init@v4 - name: Bundle Install run: bundle install - name: Build and test run: bundle exec fastlane tests
Running unit tests usually does not require complicated code-signing steps or access to shared accounts, and passwords. All this is required to deploy builds to TestFlight. As a first step, the certificates and provisioning profiles need to be made accessible for GitHub actions. Luckily fastlane also helps with this: match. Following the guide to integrate fastlane match, I created a repository accessible for GitHub Actions to store encrypted profiles and certificates. The passphrase for the certificates is saved inside GitHub Secrets. Fastlane match will then install the certificates in the keychain of the Action runner to successfully sign the build. The added lane to the Fastfile looks like this:
lane :beta_ci do bump_version create_keychain( name: "Fastlane_CI", password: "CI_Password", default_keychain: true, unlock: true, timeout: 3600, add_to_search_list: true, ) match(type: "development", readonly: true, keychain_name: 'Fastlane_CI', keychain_password: 'CI_Password') match(type: "appstore", readonly: true, keychain_name: 'Fastlane_CI', keychain_password: 'CI_Password') build_app(workspace: "Icro.xcworkspace", scheme: "Icro") upload_to_testflight(skip_waiting_for_build_processing: true, username: "firstname.lastname@example.org") end
bump_versionis just a simple internal lane to set the build number to the number of commits on
master. We need to call
create_keychainto use a specialised keychain on the Action runner. Otherwise, the build would be blocked forever, during the signing, a keychain-popup to access the installed certificates would block the execution. Two
matchactions will install the certificates for
appstoreto ensure a successful signing. Using a restricted App Store Connect user, the build gets uploaded to TestFlight. The Fastfile does not have access the defined GitHub secrets. Therefore the passphrase for match and the password for the App Store Connect account are defined as environment variables on the deployment workflow file.
name: Deploy on: release: types: [published] jobs: build: runs-on: macos-latest steps: - uses: actions/checkout@v1 - name: submodules-init uses: snickerbockers/submodules-init@v4 - name: Bundle Install run: bundle install - name: Set Appstore Connect User run: bundle exec fastlane fastlane-credentials add --username email@example.com --password $ - name: Fastlane Beta CI run: bundle exec fastlane beta_ci env: MATCH_PASSWORD: $ FASTLANE_PASSWORD: $
The deployment is triggered on every newly created release inside GitHub (just a tag). The workflow will install the bundles again, set the fastlane credentials by accessing the
APPSTORE_PASSWORDinside GitHub secrets. As a final step, the lane gets called with the
matchpassphrase and App Store Connect password defined.
With this setup in place, every push and pull request to Icro will run unit tests, every new release will automatically create and upload a new build to App Store Connect.

Spending way too little time on writing Rust, this still is a helpful guide.

“Apple set the standard that highly complex, innovative software that was only possible on the iPad could only ever earn 5 bucks from a customer forever (updates, of course, were free).”

A new Icro iOS Testflight build is available including support for fetching a micropub access token using Indieauth. I wish there was offical Testflight for Mac support!

Don’t mind me, just testing my IndieAuth flow.
