Hi, I'm Pedro!

📸 Generate screenshots for multiple device sizes

🚀 Build and upload a new version to the AppStore

🔐 Handle generate and download certificates and profiles

🤖 Configure CI

✈️ Build and upload a beta version to TestFlight

---

fastlane handles tedious tasks so you don’t have to.

---

Setup Fastlane

$ cd ios
$ gem install bundler
$ bundle init
$ echo "gem 'fastlane'" >> Gemfile
$ bundle install
# ou simplesmente (não recomendado)
# $ gem install fastlane

alias lane="bundle exec fastlane"

---

$ lane init

---

$ lane init

• Automatically create App ID on Apple Developer Portal
• Automatically create App on Apple Store Connect
• Configured Appfile
• Sample Fastfile

---

Appfile

app_identifier("io.github.mugbug.fastlaneDemo")
apple_id("pedro.zaroni@dextra-sw.com")

itc_team_id("464910") # App Store Connect Team ID
team_id("JZ2QTNWLCN") # Developer Portal Team ID

Fastfile

desc "Push a new beta build to TestFlight"
lane :beta do
  build_app(workspace: "Runner.xcworkspace", scheme: "Runner")
  upload_to_testflight
end

---

$ lane beta

** ARCHIVE FAILED **

❌ error: "Runner" requires a provisioning profile. Select a provisioning profile in the Signing & Capabilities editor. (in target 'Runner' from project 'Runner')

Using match

Using cert and sigh

---

Using match

Private keys + certificates => Github private repo

• Easy to setup new machines with only the repo access
• No need to create a profile for each team member
• Secure 🔒

⚠️ _match_ requires to revoke existing certificates

---

Using cert and sigh

• cert will make sure you have a valid certificate and its private key installed on the local machine
• sigh will make sure you have a valid provisioning profile installed locally, that matches the installed certificate

Mainly used if you don't want to revoke existing certificates

---

To get started, create a new private Git repo and run:

$ lane match init

https://codesigning.guide

Note: It's also possible to use Google Cloud or Amazon S3 to store the certificates/profiles

---

Matchfile

# Repo where profiles and certs will be stored
git_url("git@github.com:mugbug/fastlane-demo-certs.git")

storage_mode("git")

# Apple Developer Portal username
username("mugbug@example.com")

---

Creating new certificate and profile

# Fastfile

desc "Download provisioning profiles"
lane :rematch do
  match(
    type: "appstore", # or development/adhoc
    # git_branch: "my-app",
    username: "mugbug@example.com",
    force: true, # enable to always refresh profiles
    # readonly: true, # enable to prevent refreshes
  )
end

---

$ lane rematch

• Generate new certificate and import to local machine
• Create new provisioning profile for Bundle ID
• Setup Passphrase for Match storage
• Encrypt and upload certificate and profile to git repo

---

---

Let's check Xcode's Signing & Capabilities

---

Why use match?

• Full control over what happens
• Share a single code signing identity across the team
• Automatically repair broken and expired credentials
• Clean setup in minutes
• It just works™

---

Sounds good, now let's try this again:

$ lane beta

---

---

Where to go from here?

• Version bump
• Screenshots
• Release notes
• Firebase App Distribution
• Slack message
• Integrate with any CI tool
• ∞ -> beyond! 🚀
