How to automagically deploy to Testflight using Travis-CI

1. Copy the .travis.yml into your repo and edit it
   1. Replace [Workspace name] with your workspace name. If you don't have a .workspace file and wish to use your .xcodeproj file replace the -workspace flag with a -project flag followed by your project name.
   2. Replace [Scheme to use] with the Scheme you wish to use.
   3. Replace [Build configuration name] with the build configuration you want to use.
   4. Replace [Comma separated Testflight distributions lists] with the Testflight distributions lists.
   5. Replace [Name of .app file] with the name of your App. In most cases it's same name as your project name.
   6. Replace [Organization name] with the name of the organization defined in the certificate you will use to sign this App. You'll find this in your keychain. If the certificate has ([User ID]) at the end, don't forget to update [User ID]. If not, delete ([User ID]) and the brackets surrounding it.
   7. Replace [Name of provisioning file] with the file name of your provisioning file name without the extension.
2. Create the folders "scripts/travis/profile"
3. Export the following things from the Keychain app
   1. "Apple Worldwide Developer Relations Certification Authority" to scripts/travis/apple.cer
   2. Your iPhone Distribution certificate to scripts/travis/dist.cer
   3. Your iPhone Distribution private key to scripts/travis/dist.p12 (Important to choose a proper password)
4. Execute travis encrypt "KEY_PASSWORD=[Your .p12 password]" --add
5. Execute travis encrypt "TEAM_TOKEN=[Testflight team token]" --add
   1. You'll find your Team token here
6. Execute travis encrypt "API_TOKEN=[Testflight API token]" --add
   1. You'll find your API token here
7. Copy add-key.sh, remove-key.sh and testflight.sh to scripts/travis
8. Copy your mobile provisioning profile to scripts/travis/profile/
9. Stage all the new files, it should be:
   • .travis.yml
   • apple.cer
   • dist.cer
   • dist.p12
   • [Name of provisioning file].mobileprovision
   • add-key.sh
   • remove-key.sh
   • testflight.sh
10. Commit and push!
11. That's a Wrapp! ;)

Only sending to Testflight if branch is "build_testflight"

In testflight.sh on row 6 we check which branch is being built. At the moment it will only send it to Testflight if the current branch is named "build_testflight". Feel free to remove this if it doesn't suit your needs :)

add-key.sh

security create-keychain -p travis ios-build.keychain
security default-keychain -s ios-build.keychain
security unlock-keychain -p travis ios-build.keychain
security -v set-keychain-settings -lut 86400 ios-build.keychain
security import ./scripts/travis/apple.cer -k ~/Library/Keychains/ios-build.keychain -T /usr/bin/codesign
security import ./scripts/travis/dist.cer -k ~/Library/Keychains/ios-build.keychain -T /usr/bin/codesign
security import ./scripts/travis/dist.p12 -k ~/Library/Keychains/ios-build.keychain -P $KEY_PASSWORD -T /usr/bin/codesign
mkdir -p ~/Library/MobileDevice/Provisioning\ Profiles
cp ./scripts/travis/profile/* ~/Library/MobileDevice/Provisioning\ Profiles/

remove-key.sh

security delete-keychain ios-build.keychain
rm -f ~/Library/MobileDevice/Provisioning\ Profiles/*

testflight.sh

#!/bin/sh
if [[ "$TRAVIS_PULL_REQUEST" != "false" ]]; then
  echo "This is a pull request. No deployment will be done."
  exit 0
fi
if [[ "$TRAVIS_BRANCH" != "build_testflight" ]]; then
  echo "Testing on a branch other than build_testflight. No deployment will be done."
  exit 0

For anyone struggling with the entitlements error @chrismeyersfsu ran into, this change to the code signing build settings fixed it for me:
