module compiled with swift 5.3.2 cannot be imported by the swift 5.5.2 compiler

Hello, When trying to open a project written in approximately August in xcode 13.2.1 version, I get the error 'module compiled with swift 5.3.2 cannot be imported by the swift 5.5.2 compiler'. As you can see in the attachment, I get 127 errors when I run it with the 5.3.2 toolchain. How can I upgrade an existing project to version 5.5.2? Thank you in advance for your help

  • You can access Apple's official technical support for issues like these by opening a Technical Support Incident.. We do not provide support on Discord.

  • I am getting a similar issue when I switched to Xcode 13.2.1. In my case, I use carthage to build dependencies. And I only get this error when I build it in the AppCenter build server. Locally the build works fine. In both cases, using Xcode 13.2.1.

    My understanding is that carthage will build from source. Any ideas?

I'm using cocoapods-binary-cache and I'm getting the same error as yours. There is no problem when building with the actual device, but an error occurs when building with the simulator as a target.

Module compiled with Swift 5.3.2 cannot be imported by the Swift 5.5.2 compiler

Environment:

  • Xcode 13.2.1 (13C100)
  • Using a Mackbook Pro (M1 Pro, 10 Core)
  • swift-driver version: 1.26.21 Apple Swift version 5.5.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)
  • Target: arm64-apple-macosx12.0
  • No additional Swift use with other Xcode or Toolchain.

I have faced the same error. An actual device works well but the emulator makes problem.

The errors

<unknown>:0: error: unable to load standard library for target 'arm64-apple-ios12.0'
<unknown>:0: error: module compiled with Swift 5.4 cannot be imported by the Swift 5.5.2 compiler:

And I tried to change my swift version(5.5.2 -> 5.4) on Xcode via ToolChain, but it does not work.

Environment

  • Xcode: 13.2.1 (13C100)
  • MacBook Pro (MacBook Pro (13-inch, M1, 2020))
