Xcode 12: Compiling for iOS 10.0, but module 'RxSwift' has a minimum deployment target of iOS 12.0

Question

I just updated Xcode to the latest version, and the project is no longer compiling. I removed everything and tried to rebuild pods but ended up having the same issue this issue:

[x] /Users/alouanemed/Projects/App-iOS/Pods/_Prebuild/Moya/Sources/RxMoya/MoyaProvider+Rx.swift:2:8: compiling for iOS 10.0, but module 'RxSwift' has a minimum deployment target of iOS 12.0: /Users/alouanemed/Projects/App-iOS/Pods/build/Release-iphoneos/RxSwift/RxSwift.framework/Modules/RxSwift.swiftmodule/arm64-apple-ios.swiftmodule

import RxSwift ^

With cocoapods and Xcode 12, you currently need to set your Pods' deployment targets in a so-called "post-install hook".

Try adding this to the end of your Podfile:

deployment_target = '12.0'

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'] = deployment_target
            end
        end
        project.build_configurations.each do |config|
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = deployment_target
        end
    end
end
