# Bitrise Build Issue Report template ## Description of the issue After updating to Swift 4.2, Bitrise can’t build, but my mac can build ## Environment: **Where did the issue happen?** Xcode 10.0.x, on Mac OS 10.13 (High Sierra) **Which build Step causes the issue and which version of the step?** xcode-archive always latest ## Reproducibility - _Does a “Rebuild” help? (You can trigger a rebuild from the Build’s page, by clicking the “Rebuild” button in the top right corner of a finished build)_ : NO - _Does a rebuild without caches help? (You can remove the `Cache:Pull` and `Cache:Push` steps temporarily to not to use the cache, or [you can delete all the caches on the `Settings` tab of the app](http://devcenter.bitrise.io/caching/about-caching/#downloading-and-deleting-caches)._ : NO - _Does the issue happen sporadically, or every time?_ :every time - _Does upgrading the build Step to the latest version help?_ : NO - _When did the issue start?_ : ### Local reproduction _Can it be reproduced on your own Mac/PC by following our [local debug guide](http://discuss.bitrise.io/t/how-to-debug-your-build-locally-it-works-on-my-mac-pc-but-not-on-bitrise-io/392)? Please follow at least the first section (“Testing with a full clean git clone”) to make sure to test the state of the code what [bitrise.io](http://bitrise.io) will get when it does a git clone in the clean environment! If possible please note which sections you tried._ ### Local reproduction: Linux / Android (docker based) stack builds _Can it be reproduced by running the build locally, after doing a new git clone of the repository into the `/tmp` directory and running the build from there with the Bitrise CLI ( [https://www.bitrise.io/cli](https://www.bitrise.io/cli) )? If no, can it be reproduced with Docker (using the same docker images / environment we use on [bitrise.io](http://bitrise.io))? Related guide: [http://devcenter.bitrise.io/docker/run-your-build-locally-in-docker/](http://devcenter.bitrise.io/docker/run-your-build-locally-in-docker/) ._ ## Build log _Please copy paste the build’s [bitrise.io](http://bitrise.io) URL here (or if the issue happens somewhere else then the full logs), or if you can’t share the url / log here then send the url or full log through a private channel (e.g. email - [https://www.bitrise.io/contact](https://www.bitrise.io/contact) ), with a link to the related Discuss issue._ ---

Hi @studygear, Sorry to hear about the issue. Can you please include a build URL where we could look into it? ---
