Travis
Hosted Continuous Integration service
Configuration file in your project (.travis.yml)
Define SDK, build env and output
custom scripts
Connected to Github
Triggers in every push and pull request
Available for many platforms

Travis Setup (.travis.yml)
It’s not using the iPhone SDK
code signing is needed
Doesn’t differentiate between branches
Doesn’t archive
Doesn’t distribute
language: objective-c
xcode_project: MyNewProject.xcodeproj
xcode_scheme: MyNewProjectSharedScheme
iPhone SDK
custom build per branch
generate .ipa
distribute

Import keys (import-keys.sh)
# 1. Create keychain
security create-keychain -p travis ios-build.keychain
# 2. Make as default
security default-keychain -s ios-build.keychain
# 3. Unlock keychain
security unlock-keychain -p travis ios-build.keychain
# 4. Add certificates to keychain
security import ./ios-travis-ci/certificates/dist.cer -k ios-build.keychain -T /usr/bin/codesign
security import ./ios-travis-ci/certificates/dist.p12 -k ios-build.keychain -P $KEY_DIST_PASSWORD -T /usr/bin/codesign
# 5. Copying provisioning profile to Travis
mkdir -p ~/Library/MobileDevice/Provisioning Profiles

Security
You can encrypt environment variables using
Travis command line tool on your terminal:
~ $ travis encrypt ‘KEY_DIST_PASSWORD=abc123’ –add
Passing the option “--add” will automatically add the secure
key to your .travis.yml
env:
global:
- secure: Pz3cxDffsdafasf34324fdsf232fdsfdsf3fdsf

Move the scripts away from the app
repository (Optional)
Maintenance 👍
Reusable 👍
Slower builds 👎
…
git:
submodules: false
before_install:
- git submodule init ios-travis-ci
- git submodule update --remote --merge ios-travis-ci

Result
Automate tasks
App is distributed
No manual configuration
Different actions between branches
5 different apps to test concurrently
(@banaslee’s phone)

Some pain left
Provisioning profile included on project 👎
Very long shell script files 👎
Can’t scale 👎
Very Travis dependent👎

Fastlane by @KrauseFx
Lets you define and run your deployment
pipelines for different environments.
Ruby gem
Powerful toolchain
Automates certificates and
prov.profile installs
Flexible
Open source

Fastlane / Example
# ../fastlane/Fastfile
#...
lane :deploy do
# Installing certificates
cert( development: true, username: "cibot@getyourguide.com")
# Fetching and installing proviosning profiles
sigh( adhoc: true, force: true, filename: "myFile.mobileprovision")
# Build project
gym( scheme: "MyApp", workspace: "MyApp.xcworkspace", configuration: ENV["APP_BUILD_CONFIG"])
# Shipping
hockey( api_token: '...', ipa: './app.ipa', notes: "Changelog")
end
#...

Fastlane / Example .travis.yml
env:
global:
script:
- bundle exec fastlane deploy
Scalable 👍
Faster 👍
Focused on Apple environment 👎

Thanks for your time
