How to compile an iOS project from command line

Question

I want to assemble/compile a workspace with cocoapods on it but without:

• Archiving.
• Need to setup credentials or pem files.

Something like: xcodebuild assemble

I want to know if the code compiles but not generate an archive or a deployed artifact.

I tried fastlane/gym but it tries to create an archive.

Using xcodebuild

You can compile a project with the following command:

xcodebuild <path to project> -scheme <scheme name> build

Because you are using cocoapods, you should compile using the workspace, instead of the project, like this:

xcodebuild -workspace <path to workspace file> -scheme <scheme name> build

If the swift version is not set in the cocoapods target there is a workaround by adding the following to your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.1'
   end
  end
end

Using fastlane

Another way is using build_app from fastlane, like:

build_app(scheme: 'YourScheme',
          workspace: 'YourProject.xcworkspace',
          skip_archive: true,
          skip_package_ipa: true,
          include_bitcode: false)

I prefer this way, since it makes it simpler and uses xcpretty that will print the output nicer than xcodebuild.
