Key Fastlane Traits for App Uploads
Fastlane groups tools to make the hard work of app uploads easy. It helps both iOS and Android users with a single way to speed up app pushing and save hours. These points build up Fastlane's fast upload steps.
Tools to Build and Share Easily
Fastlane's top power is how it makes the whole build and share steps run by itself. With a simple command, it deals with code making, build making, and store sendings.
For iOS, Fastlane makes IPA files for TestFlight or the App Store. For Android, it makes APK or AAB files for the Google Play store. It also fixes app info, with things like changes, key words, and new update notes, all in one go.
One more big win is its auto picture making. Fastlane takes pics across many device types and ways, making the work of changing app store looks for many places less by a lot.
As dev Austin Louden said:
"Software like @FastlaneTools makes me glad to build stuff. Still kinda shocked that it's possible to send builds to Testflight w/ 1 command"
Along with making and sharing, Fastlane also makes signing and setting up simpler, giving a more smooth flow of work.
Handling Certificates and Profiles
Working with certificates and profiles is a hard part of making iOS apps. Fastlane’s match tool helps a lot by making a shared signing ID for your team.
Match keeps certificates and profiles safe in a Git store, Google Cloud, or Amazon S3. This setup lets new people or machines get ready in under a minute. It also takes care of certificate updates and fixes on its own. For teams with ongoing setups, the --readonly option makes sure these systems can get to certificates without making new ones by mistake.
Fastlane has other tools like cert and sigh to deal directly with certificates and profiles. All these tools help take the pain out of code signing.
Custom Setting Files
Fastlane has two main setting files - Appfile and Fastfile - to fit any project and make work flow better. These files help manage project details and automate putting out tasks.
The Appfile saves important info like your Apple ID, team ID, and app IDs. By putting all this in one place, you only need to set it once, and all Fastlane tools use it without extra steps.
The Fastfile is where you set up custom work flows, or "lanes." These lanes can mix many actions - like making the app, running tests, making screenshots, and sending them to TestFlight - into one command.
The use of these setting files is clear in real work. For instance, Rently saw big time savings after using Fastlane. Their Android make time for six app types went from over 40 minutes of manual work to just 19.5 minutes. For iOS, they cut their process from over two hours to just 26 minutes.
Keeping the Appfile and Fastfile in version control makes sure work flows are easy to share among team members, keeping things the same across setups. With this kind of skill, Fastlane can deal with nearly any project’s needs.
How to Use Fastlane to Speed Up App Submissions
Using Fastlane to speed up app submissions can make the long task of making, setting up, and putting apps out there much easier. Once you set it up well, you can cut down on time and lower mistakes in your work flow.
Putting Fastlane in Place and The First Steps
First, it's smart to put in Fastlane with Bundler. Why? Bundler keeps the same versions and makes things run smooth among your team members. It's a more sure bet than other ways like Homebrew or system Ruby.
Before you begin putting it in, here are some things to check:
For iOS work, make sure the newest Xcode command line tools are there.
For Android work, add an APK to your app on the Google Play Console at least once before using the supply tool.
Then, add Fastlane to your Gemfile and run bundle install. Go to your project area and start Fastlane by typing fastlane init.
For sign in, use the App Store Connect API key for iOS and a Google Developers Service Account file for Android. Also, set your local setting for stuff (LC_ALL and LANG) to UTF-8 to dodge any trouble with how letters look while building and uploading.
A top use of Fastlane is seen at TheWidlarzGroup, who use it to cut down work on making and putting out mobile apps for both iOS and Android. This saves them both time and hard work.
After setting it up and signing in, you can make lanes in your Fastfile to cut down specific tasks.
Making and Using Lanes for Less Work
Lanes are the main part of Fastlane cutting down work. They are custom workflows that put many actions into one command, all listed in your Fastfile.
To make a lane, open your Fastfile and put it in the right spot for your platform (like platform :ios do or platform :android do). Use the desc sign to talk about what each lane does, helping your team know what it’s for.
Here’s what you might add in your lanes:
increment_build_numberto change build numbers for new releases.matchto share signing papers among your team.gymto make and wrap up iOS apps.
For putting apps out:
pilotto load apps to TestFlight.deliverto manage uploads to the App Store, including all the small details.supplyto handle putting things on the Google Play Console.
Lanes can also use other lanes, letting you reuse setups. You can give command-line stuff for choices, and use before_each and after_each parts to get ready and clean up around each lane.
Check this real-life case: Ergun Uğur Güner cut down his Android app work with a lane called "distribute_alpha_google_play." This lane made the project with Gradle, sent the app pack to the Google Play Console, and told Slack when it did well. It even changed the version code by looking at alpha and production lines for the newest version.
Once your lanes are set, you can make things even smoother by handling metadata and pictures on their own.
Making Metadata and Picture Uploads Automatic
Change the app store details by hand is hard, most when your app is in many tongues or on more than one device. Fastlane's deliver tool helps with this by making metadata, pictures, and binary shares to App Store Connect automatic.
First, run fastlane deliver init in your project spot. This sets up the folders and files you need. If you have stuff on App Store Connect already, you can get it with deliver download_metadata and deliver download_screenshots.
Set up your metadata with .txt files for each tongue and type. It's wise to keep metadata in Git for easy reach, but don't put up pictures due to their large size.
To send everything, run fastlane deliver. If you want to send your app for check in one move, use fastlane deliver --ipa "App.ipa" --submit_for_review. For auto CI flows, using upload_to_app_store lane with force: true keeps the process going without stops.
For pictures, Fastlane's snapshot tool is top. Once set, it lets anyone in your team make steady pictures with just one order. Keep the setup in your stash to keep looks the same through updates.
Go for Fastlane When Sending Apps
Ditching step-by-step app sending for automated flows with Fastlane has changed the game in app launching. Many development groups now lean on automation to make their work smooth. Let's see how Fastlane does more than just automate; it fits well with today's app making ways.
Save Time and Money
Sending apps by hand eats up a lot of time with the same tasks over and over, using up hours that are better spent on creating. Fastlane mixes things up by handling chores like code signing and adding app details on its own. Lucas Buchalla Sesti, a coder who uses Fastlane, points out how big the shift was:
"Using Fastlane brings many benefits to the application development and deployment process. It eliminates time-consuming manual processes and saves a lot of time by automating repetitive tasks."
Time saved is huge. For example, a team that runs over 20 apps cut their work time from three days to just 20-30 minutes by using GitHub Actions with Fastlane. This not only saves money but lets builders make new features and better the user's feel. Plus, using machines means fewer human mistakes which can hold up or mess up the app release.
Work gets bigger and stays good
Fastlane is great at making plans that grow with your team. As teams get big and need to put out work often, doing things by hand can mess up. Fastlane helps by keeping the steps the same no matter who does it or when. It lets teams make plans that fit their needs well.
You can add on tools to Fastlane. Things like Firebase, Slack messages, and crash checks can link right into your work plan. As more people join, your work keeps going well without slowing down. This keeps you ready for more work and fits well with CI/CD setups, making them stronger.
Links well with CI/CD setups
Being able to join with CI/CD systems is a big plus for Fastlane. Keeping builds and delivery going all the time is a must now, and Fastlane works smooth with CI tools. For instance, it pairs well with GitHub Actions for making iOS apps. GitHub Actions handle the big CI/CD work, and Fastlane takes care of app-specific stuff, making sure things go out well and on time.
Fastlane can do the whole app getting out job by itself, making it so code changes are checked, built, signed, and sent out without needing hands-on. It’s also good with keeping CI/CD secrets safe, holding onto key info safely.
Builders praise these perks. As @deadwinter said:
"Some free advice: if you develop mobile apps you really need Fastlane. It's a game changer."
