Build Error After Updating SDK

RTC — Wed, 14 May 2025 18:17:02 GMT

After trying to update the SDK via SPM, I am getting a build error with cmark-gfm. This package seemed to be added as part of the ArcGIS Maps SDK for Swift Toolkit update along with the Swift Markdown package.

I have tried removing and reinstalling app packages and a few other thing but noting seems to work. If I revert back to SDK version 200.5, I do not have any issue, only from 200.6 and up.

It's a bit hard to tell what is the problem… might be an issue with Swift Package Manager. The 2 things I would suggest are:

- Can you try create a new app project with 200.6.0 toolkit and see if it compiles?

- If it compiles, can you try cleaning out the Derived Data folder, or the artifacts folder for the specific app project? So the Swift Packages would have a clean slate to begin with.

The package involved is a dependency of https://github.com/swiftlang/swift-markdown which we added during 200.6 release.

Yes, if I start with new project it works only when I try to update an existing project do I get the errors.

What version of Xcode are you using? If you start a clean project and add 200.5, then upgrade that project to 200.6 does it reproduce the issue? Do you have a reproducible case you can get to us?

I am using Xcode Version 16.3 (16E140). If I start with a blank project on 200.5 then update, it works. I will see if I can create a simple project that recreates the issue.

I was trying to create a new project but keep getting this error now and I can't seem to load any version of the SDK.

Thanks for reporting. We are seeing this issue and working on fixing it. For now you can add a dependency to the main branch. Sorry for the inconvenience!

Hello Ting,

I can't seem to add it no matter what I try. Is this something that will be resolved soon? I am stuck as my project now does not have any version of the dependency and I can get one to download via SPM.
What do you mean by "For now you can add a dependency to the main branch."

Yes, we are actively working on it. Due to a mistake, some commit history was messed up, and it appears to affect the tagged release.

A temporary workaround is to select "Branch" as Dependency Rule in SPM, and type in "main" to use the main branch to add the package. Again, sorry for the inconvenience - I'll let you know as soon as we fix it.

The 200.7.1 release tag should resolve correctly now. Let me know if you still experience the problem. 🙂

Thanks Ting, I am able to get 200.7.1 to update now but I am still having the same errors as posted above. I have tried clearing/resetting the SPM cache and all the other suggestions but can't get it to compile for my existing project.

Gotcha. From the screenshot you provided, we are guessing along the line of -fsanitize compiler flag, or Undefined Behavior Sanitizer in the Xcode scheme manager.

Can you see if it is checked under the "Runtime Sanitization" section (Scheme > Run > Diagnostics)? If so, we'll need to come up with a test project to mimic your environment. Thanks!

Edit: upon further discussion, it seems to be a problem with a legacy setting (enableUBSanitizer = "YES") in the xcscheme file. After removing it following these instructions, the problem was solved.

Ok, I will look into that and get back to you. Thanks!
