Mastering Bitrise workflows for steady iOS app supply

Fast intro to Bitrise workflows

A Bitrise workflow is a group of Steps. When a construct of an app is operating, the steps will likely be executed within the order that’s outlined within the workflow. – hyperlink

A step is an easy illustration of a construct job, they run one after one other within the workflow. Inserting a brand new one is fairly easy, there’s a + button in between each 2 steps, so you’ll be able to add a brand new ingredient simply to the correct place with a single click on. The workflow editor is a very nice approach of including, eradicating or arranging them, nonetheless, if you’re conversant in the bitrise.yml file format, it may be quicker to edit that manually.

There are many out there open supply steps for Bitrise, additionally you probably have some actually particular want, you’ll be able to write your personal one through the use of a easy shell script or golang. Anyway, it is extra doubtless that you will discover what you are in search of within the step library, so don’t fret an excessive amount of about this, as a result of “there’s a step for that”.

Organising an automatic nightly construct

After the fast intro, let’s dive into the technical particulars of my workflow setup. Normally, I wish to have an automatic nightly construct that creates an inside launch straight out from the dev department of the git repository. This fashion all the newest modifications are going to be out there for inside testing on daily basis within the morning.

Git workflow:

I am principally following the succesfull git branching mannequin methodology created by Vincent Driessen again in 2010. It is actually good things, if you do not have a branching technique you need to learn this text too, as a result of it is fairly a gem. 💎

Primary iOS Bitrise setup

After you arrange your iOS utility on Bitrise, by default there’s a major workflow primarily based on the platform of your app. We have now to alter this primary one somewhat bit. First, let’s rename it to nightly-build. I at all times use the next steps for my iOS builds, however not crucial within the following order:

I like to make use of the Bitrise cache mechanism to cache Pods. With a view to do that you simply have so as to add a brand new setting variable known as BITRISE_CACHE_DIR with the next worth: ./Pods -> ./Podfile.lock. Utilizing this system will velocity up your construct time if you’re coping with a lot of CocoaPods.

I additionally favor to make use of the set venture quantity step to synchronize my construct quantity with my precise Bitrise construct quantity. The one factor I’ve to set is the Information.plist file’s path, which is normally situated beneath the next place: $BITRISE_SCHEME/Property/Information.plist (may very well be totally different for you).

At this level, I will assume that you just exported the required provisioning profiles otherwise you’re utilizing the auto provision step. That is the toughest a part of the job, however Codesigndoc is an incredible instrument, it could possibly assist you a large number, so go forward & attempt it. You will not remorse it. So at this level when you’ve completed every thing proper you need to have a workflow that builds with out errors. It is time to arrange a schedule for it. ⏰

Construct schedule

For those who press the Begin/Schedule a Construct button you’ll be able to allow the “Schedule this construct” choice. The method is actually easy, you’ll be able to enter the hour and minute values, and choose any given days to kick off your builds. It is also attainable to set a selected workflow and when you go to the superior tab, there will likely be a curl command on the underside of the checklist that can be utilized to start out the construct remotely. 👍

Set off on push as an alternative of scheduled builds

On the Triggers tab of the Workflow Editor, you’ll be able to map a department to a given workflow. If a push occasion occurs on that department a brand new construct will likely be triggered on Bitrise. This is available in fairly useful when you do not wish to depend on a hard and fast schedule, however somewhat ship out new variations from the release-x.y branches.

Organizing your workflows

Thus far so good, we have now a working steady integration service for our growth course of. Nevertheless, if you would like to assist extra supply strategies from a number of branches issues can get fairly difficult. The very first thing that you are able to do is to duplicate your complete workflow, however in the long run that may trigger some bother.

For those who comply with the standard git branching method you may must create separate supply workflows for the nightly, preview and launch builds. As a substitute of copying the entire workflow, we’re going to create a chain of smaller workflows. This fashion if you must change a parameter in a step, you do not have to manually alter that setting in each different occasion within the duplicates. Right here is my answer. 🚀

Construct vs supply

The construct and the supply processes are fairly totally different. Constructing an artifact by the CI service might be separated from delivering the top product. That is the very same strategy that I wish to comply with in my setup. The one downside right here is cell provisioning. Sadly, you’ll be able to’t merely resign your beforehand generated product, so the supply course of has to construct the ultimate signed iOS app through the use of Xcode. This particular codesign concern is the explanation why I’m going with 3 levels.

Preparation, supply, notification levels

So principally these are workflows that may be triggered individually, however they are often linked collectively they usually all have totally different functions. Let me give some particulars.

Preparation

On this section I setup all the fundamental stuff that is required for the Xcode construct course of. It would not actually matter how Xcode will signal the ultimate product, the one objective of this workflow is to make it possible for every thing is prepared for the precise construct course of. 🔨

Supply

The principle objective of the supply course of is to construct & ship the signed utility to its correct place. That may be a Bitrise.io deployment or a TestFlight supply utilizing fastlane instruments. I solely must duplicate this stage for each launch goal.

Notification

The final stage is all about notifying individuals, so you will get notified through your most well-liked notification system a couple of profitable supply. In a lot of the instances I’ve a devoted Slack channel for construct standing notifications, so every thing goes there by default. 📩

Constructing by triggering workflows

As you’ll be able to see it is comparatively straightforward to separate the unique nightly-build workflow into smaller reusable items, and set off one workflow earlier than (or after) one other. Let’s do precisely like this. Listed here are the brand new workflow elements.

Preparation

• Activate SSH key (RSA non-public key)
• Git Clone Repository
• Bitrise.io Cache:Pull (for CocoaPods cache)
• Run CocoaPods set up (if I’ve pods)
• Bitrise.io Cache:Push
• Recreate Person Schemes
• Set Xcode Undertaking Construct Quantity
• Certificates and profile installer (or iOS Auto Provision)

Supply (nightly)

• Xcode Archive & Export for iOS
• Deploy to Bitrise.io – Apps, Logs, Artifacts

Notification

• Ship a Slack message (optionally available)

So truly there are 4 workflows now, the 4th one is simply calling the preparation, All of the required workflows are literally known as earlier than the nightly-build. We will say that the nightly-build workflow is simply an empty container that is answerable for calling the opposite 3 (preparation, nightly-delivery and the notification) levels within the correct order. I favor having these names for the levels:

• preparation: generic reusable part
• nightly-delivery: builds & deploys ipa to Bitrise.io
• notification: generic reusable part
• nightly-build: scheduled (or triggered) builds from dev

Let’s make yet one more supply stage, that builds from the grasp department and uploads the artifact for TestFlight beta testing.

Preview (TestFlight launch) builds utilizing App Retailer join supply stage

Creating a brand new workflow for App Retailer join builds is approach simpler with this setup. As you’ll be able to see the preparation & notification levels are kind of the identical, you solely must create a brand new supply methodology (preview-delivery) for the TestFlight builds. Right here is the overview of your complete workflow setup:

Preview construct

• Preparation
• Supply (preview)
• Notification

Supply (preview)

As I stated earlier than, you simply must duplicate the nightly-delivery circulation and change the deployment step with the Deploy to iTunes Join step, that’ll push your closing product to the correct place. On this step you will must set your Apple identifier and a few particulars concerning the supply, however that is fairly easy and there’s a fairly good description for every out there choice. At all times just be sure you have all of the required entitlements & code signing certificates for this supply goal too! 🔥

As you’ll be able to see having smaller reusable elements as an alternative of only one large workflow clearly has some advantages. Constantly delivering your utility might be actually efficient, particularly if you’re utilizing the correct instruments with the right setup. I hope this tutorial will enable you to to have a greater expertise.

For those who’ve by no means heard about Bitrise earlier than you need to positively attempt it out, as a result of presently it is top-of-the-line CI/CD options for cell utility builders. 😉
