You can search Google for that but I will note the solution here btw:

Add the below code to the Podfile

post_install do |installer|
    installer.generated_projects.each do |project|
          project.targets.each do |target|
              target.build_configurations.each do |config|
                  config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
               end
          end
   end
end

Can someone of the maintainers update to a minimum deployment target higher than iOS 11?

Sorry. I am not familiar to Podfile. May I know where can I locate/ generate the Podfile?

I try to open FSCalendarExamples.xcworkspace using XCode. In every targets

• FSCalendarExample
• FSCalendar
• FSCalendarTests
• FSCalendarExampleUITests

I change the Minimum Deployments to 12.0

Still, I am getting the same error.
