I am in the process of upgrading an outdated application to all of the latest versions of SDK's and one of the parts was quite a complex build- and signing process using fastlane and Circle CI. Everything works except the last part where the built output gets pushed to the iTunes App Store. I've noticed that around WWDC the interface changed and fastlane needed an update to 1.150 or higher to work with that new API. The instance of Circle CI seems stuck at something like 1.138 and shell scripts to try to update it don't seem to work because of security limitations.
What is the official approach to get the latest version of fastlane in Circle CI?
Content of the Gemfile:
source "https://rubygems.org"
gem 'fastlane'
In a shell script:
bundle install
Not sure if "offical", but I'd recommend to use bundle.
Add a Gemfile to your project like so:
source "https://rubygems.org"
gem "fastlane"
run bundle update, and add the resulting Gemfile.lock to your version control. Now invoke fastlane using bundle exec fastlane ...
