This is an example project for the first virtual Bitrise User Group (BUG) talk, "Automating Dark Mode Screenshots with Xcode 11".

The included bitrise.yml includes the workflow screenshots from the talk.

If you want to run directly on Bitrise, fork the project & add a new app to your Bitrise account with your fork's GitHub URL. You can set the Bitrise app to be Public to take advantage of Bitrise's open source free usage.

Once set-up, open up the Workflow Editor & go to the bitrise.yml tab & you can edit in the changes you find in the bitrise.yml file in this repository.

Run the screenshots workflow

Some of the script steps are overzealous & will modify settings in all installed Simulators. This isn't a problem when running on Bitrise since Bitrise uses a VM, but if you run this locally, you may experience issues that will require you to reset the Simulators via xcrun simctl erase <device>.

To avoid these issues, modify these scripts in the bitrise.yml to give a specific Simulator or Simulators you want to modify.

For example,

find ~/Library/Developer/CoreSimulator/Devices/* -type d -maxdepth 0 -exec /usr/libexec/PlistBuddy -c "Delete :AppleLanguages" -c "Add :AppleLanguages array" -c "Add :AppleLanguages:0 string $CHARGEPOINT_IOS_DEVICE_LANGUAGE" -c "Delete :AppleLocale" -c "Add :AppleLocale string $CHARGEPOINT_IOS_DEVICE_REGION" {}/data/Library/Preferences/.GlobalPreferences.plist \;

Could be rewritten to the following for the Simulator AFA116C5-FFF2-4314-A4F5-7599DC80C60A

/usr/libexec/PlistBuddy -c "Delete :AppleLanguages" -c "Add :AppleLanguages array" -c "Add :AppleLanguages:0 string $CHARGEPOINT_IOS_DEVICE_LANGUAGE" -c "Delete :AppleLocale" -c "Add :AppleLocale string $CHARGEPOINT_IOS_DEVICE_REGION" ~/Library/Developer/CoreSimulator/Devices/AFA116C5-FFF2-4314-A4F5-7599DC80C60A/data/Library/Preferences/.GlobalPreferences.plist

In particular, any of the Simulator modifying commands (changing languages, changing Dark Mode/Light Mode) should be reviewed & modified for use on a non-VM.

Please review the warning above if you're not running in a VM before doing the following.

Install the Bitrise CLI tools

brew update && brew install bitrise

Then you can run by doing

bitrise run --workflow screenshots
