[CI/CD] Disabling fastlane Update Check and Changelog Logs

Overview

This post covers how to disable fastlane’s update check log and changelog log.

Introduction

When a lane execution finishes, regardless of whether it succeeds or fails, an update check and changelog log like the one below is printed, making it inconvenient to review the lane execution logs. We get it, there’s an update – now stop the logs!

#######################################################################
# fastlane 2.201.1 is available. You are on 2.196.0.
# You should use the latest version.
# Please update using `bundle update fastlane`.

Steps

1. Disable Only the Changelog Log

• Add the following global environment variable to your shell configuration file.

  code .zshrc
  

  export FASTLANE_HIDE_CHANGELOG="1"
  

  source .zshrc
  

• After completely closing and reopening the shell, running a lane will print only the update check log as shown below.

2. Disable Both Update Check and Changelog Logs

• Add the following global environment variable to your shell configuration file.

  code .zshrc
  

  export FASTLANE_SKIP_UPDATE_CHECK="1"
  

  source .zshrc
  

• After completely closing and reopening the shell, running a lane will no longer print any such logs.
