Targeting multiple versions of iOS to your .travis.yml

Question

I am new to Travis CI and created a basic build and testing against one project and environment. .travis.ymlas follows:

language: objective-c
osx_image: xcode7
xcode_project: ./[project]/[project].xcodeproj
xcode_scheme: [project]
xcode_sdk: iphonesimulator9.0

This works great, but I also want to test. other versions of the iOS simulator (for example, 8.4).

I understand that I can use xctoolfrom a script section, as in mine .travis.yml, and this works fine too:

script:      
  xctool -project ./[project]/[project].xcodeproj -scheme [project] -sdk iphonesimulator9.0 build test

However, I do not see how to launch any other version of iOS. Objective-C docs for Travis CI say that for the simulator iOS versions are available for osx_image: xcode7, but when $ xcodebuild -version -sdklaunched on CI it only shows the availability of iOS 9.

What am I missing here to test other versions of iOS against installing Xcode?

Answer 1

:

$ xcrun instruments -s devices

:

Known Devices:
Travis’s Mac (129) [00000000-0000-1000-8000-005056A6DCD8]
iPad 2 (8.1) [22540C0C-46B4-4FF8-9B74-6321081CA975]
iPad 2 (8.2) [03655E8B-725B-4C03-A505-8EEA0BE5A966]
iPad 2 (8.3) [BBC2737B-BE8D-403B-804F-5A36560AD47B]

etc...

, env vars () UDID /, . script /. .travis.yml :

language: objective-c
osx_image: xcode7

## Create a build matrix to execute against multiple simulators/iOS versions
## The UDID will be used below to determin the destination to test against
## where the script section will be run once for each definition
## ISO_DEVICE is not used in the script but is useful to know what OS version is tested and will show up in Travis to make it easer to read
env:
  - UDID="FCBB11B4-D7C8-4085-9067-2CEDA2BFC895", IOS_DEVICE="iPhone 6 Plus (9.0)"
  # - UDID="363ADE93-270B-4C2E-9286-C3C1FABE3CDD", IOS_DEVICE="iPhone 4s (8.1)"
  - UDID="BE52C183-B4AF-408D-AE90-278FA4AD89EC", IOS_DEVICE="iPhone 5 (8.3)"
  - UDID="FCBB11B4-D7C8-4085-9067-2CEDA2BFC895", IOS_DEVICE="iPhone 6 Plus (9.0)"
  - UDID="BEEA639C-46EB-48EF-8377-A22B781A7EE2", IOS_DEVICE="iPad Air 2 (8.4)"

### Setting up the simulator for auto-test and running the build via the xcodebuild tool:
script:
  # The xcrun with devices here will print out a list of available devices you can snag the UDIDs for
  - xcrun instruments -s devices
  - echo staring build and test...
  - open -a "simulator" --args -CurrentDeviceUDID $UDID
  - xcodebuild test -project ./MovingHelper/MovingHelper.xcodeproj -scheme MovingHelper -configuration Debug -sdk iphonesimulator -destination "platform=iOS Simulator,id=$UDID"
  - osascript -e 'tell app "Simulator" to quit'
