xcode 13.3 - fatal error - SwiftSyntax.ParserError 1

[SredzinskiPatryk]

MockoloFramework/SourceParser.swift:103: Fatal error: The operation couldn’t be completed. (SwiftSyntax.ParserError error 1.)

I do receive that error after updating my Xcode to 13.3. I was working previously on 13.2.1

same issue with brew installation (1.7.0).

It's probably linked to the swift 5.6 compatibility (cf. Package.swift line 9)

var mockoloFrameworkTargetDependencies: [Target.Dependency] = [
//    .product(name: "SwiftSyntax", package: "SwiftSyntax"),
]

I rebuild it from source code (option 4 in the installation doc) and removed this line in the Package.swift and solved the issue.

What version of Mockolo is installed by Homebrew? I am wondering if 1.7.0 also causes an error.

[patryk-sredzinski]

Yes it fails on 1.7.0

Tested on CI (code magic) and local Mac

I have version 1.7.0 and have same issue with Xcode 13.3

Hello,

Any news with this issue, I'm pretty sure my quick fix is not the proper way to fix it. I didn't check what was the purpose of this array of dependencies.

Cheers.

I have same issue with Xcode 13.3. Mockolo was installed by Mint.

I have same issue with Xcode 13.3. I'm using Mockolo v1.7.0 installed by Homebrew.

[patryk-sredzinski]

1.7.0 works on 13.3 when installed using MINT

Ran into the same issue. Worked if I cloned it and ran it locally. Reinstalling and building from source fixed it for me.

brew reinstall --build-from-source mockolo

I think this is an issue caused by brew and not the source code, can we open a ticket there and close this one?

[Solace-Studios]

Is there a link to the brew ticket?

[tinder-maxwellelliott]

Is there a link to the brew ticket?

Feel free to make another, or even better make a PR to the brew formula

For anyone who installs mockolo by Mint or Homebrew: This happened by missing lib_InternalSwiftSyntaxParser.dylib come along with the mockolo released binary. We need to fix how Mint and Homebrew install these files.

My workaround: Step 1: Download tar.gz binary zipped file from https://github.com/uber/mockolo/releases/tag/1.7.1 Step 2: Extract, and copy all the files in the extracted folder into the current installed folder. For Mint:

~/.mint/packages/github.com_uber_mockolo/build/<your_installed_version>/

For Homebrew:

/opt/homebrew/Cellar/mockolo/<your_installed_version>/bin

I think this error had already been fixed since 1.8.0.
