Command CompileSwiftSources failed with a nonzero exit code XCode 13

Question

I am trying to run a project on the Xcode13, after running a pod cache clean --all, deleting the derived data, and running a pod update. When I clean the project and build it the following error appears:

Answer 1

I had this problem surface in Xcode 13.0.

Mohamed Tarek's solution worked for me, but…

I was using cocoapods, so I needed a solution not blown away by pod install; or more specifically fixed with pod install.

Adding the following to the bottom of the Podfile resolved it.

post_install do |installer|   installer.pods_project.targets.each do |target|     target.build_configurations.each do |config|     # some older pods don't support some architectures, anything over iOS 11 resolves that       config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'     end   end end

I also faced this issue, and it seems that there is a known issue on Xcode 13 as mentioned in this document: https://developer.apple.com/documentation/Xcode-Release-Notes/xcode-13-release-notes

Swift libraries depending on Combine may fail to build for targets including armv7 and i386 architectures. (82183186, 82189214)

Workaround: Use an updated version of the library that isn’t impacted (if available) or remove armv7 and i386 support (for example, increase the deployment target of the library to iOS 11 or higher).

If your app is for iOS 11 or higher, one of the libraries should be modified to target iOS 11 or higher (e.g., my app is for iOS 12 or higher).

For example, I am using GRDB.swift, and its minimum iOS version is 10.0. There was a discussion as an issue of this repo, and I followed that comment to solve this issue as follows:

1. Fork the repository
2. Change Package.swift to modify the minimum iOS version like:

let package = Package( name: "GRDB", platforms: [     .iOS("12.0"),   // changed here     .macOS("10.10"),     .tvOS("9.0"),     .watchOS("2.0"), ], ... 

3. Modify Podfile or Swift Package Manager (SPM) config to use my forked repository

I am using five libraries via SPM in my Xcode project, but applying the above method to only one of those libraries solved this issue.
