Swift Package Github Action CI [duplicate] - github

Question

I have swift package for iOS apps (it needs UIKit to run). I wan't to build this package using Github action this is how my workflow looks like
name: Swift
on:
push:
branches: [ main ]
pull_request:
branches: [ main ]
jobs:
build:
runs-on: macos-latest
steps:
- uses: actions/checkout#v2
- uses: YOCKOW/Action-setup-swift#master
with:
swift-version: '5.3'
- name: Build
run: swift build -v
- name: Run tests
run: swift test -v
When I run this build I got error: no such module 'UIKit'.
So I have 2 options:
make my package UIKit independent (actually don't know how)
configure build to run on iOS specifically
What should I do?

Answer 1

We're using xcodebuild instead of swift build to do platform specific CI from GitHub Actions. See specific example at https://github.com/firebase/firebase-ios-sdk/blob/master/.github/workflows/spm.yml and https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/build.sh#L540

The simplest approach as of 2022 is to use xcodebuild like stated above.
Condensed to the basics, the script can be as simple as this:
# This workflow will build a Swift project
# For more information see: https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-swift
name: Build and Test
on:
pull_request:
branches: [ "main" ]
jobs:
build:
runs-on: macos-latest
steps:
- uses: actions/checkout#v3
# Sanity check to make sure we use a valid device in the next step
- name: List available devices
run: xcrun simctl list devicetypes
#generic/platform=iOS is sufficient for just building, - but need to specify concrete destination for tests
- name: Build and run tests
run: xcodebuild test -scheme YourSchemeNameHere -destination 'platform=iOS Simulator,name=iPhone 13 Pro' #or any other name from the list of sim devices
This is enough to build the project and run tests on it.
In some cases you may need to install a later version of Swift than what's available by default on Github Actions, - you can use a third party step for that and use xcode-select.
