Swiftlint 0.39 library not loaded

Describe the bug

swiftlint always crashes after updating to version 0.39 via Homebrew. We've tried this on 3 systems and seen the same issue.

We have tried installing "Swift 5 Runtime Support for Command Line Tools" as per the known issues but the systems are too new to allow this to be installed.

We have downgraded to 0.38.2 which is working fine.

Complete output when running SwiftLint, including the stack trace and command used

$ swiftlint lint
dyld: Library not loaded: @rpath/lib_InternalSwiftSyntaxParser.dylib
  Referenced from: /usr/local/bin/swiftlint
  Reason: image not found
Abort trap: 6

Environment

• SwiftLint version: 0.39

• macOS versions: 10.15.3 && 10.14.6

• Installation method used: Homebrew

• Are you using nested configurations?
  If so, paste their relative paths and respective contents.

• Which Xcode version are you using: 11.3

• Do you have a sample that shows the issue? Run `swiftlint"

@Oliver-Kirkland-Evoke does it work if you try brew reinstall --build-from-source swiftlint?

Same issue, Installation method used: Cocoapods

Can you post my details about your environment? I can image why using homebrew wouldn't work, but using CP should work fine 🤔

We have the same problem. Integration is also via Cocoapods, Xcode 11.3.1.

[marcelofabri]

OK, so looks like the issue is that the binary is somehow hardcoding the path to the Xcode path from the machine that created the binary:

$ DYLD_PRINT_RPATHS=1 swiftlint help
RPATH failed expanding     @rpath/lib_InternalSwiftSyntaxParser.dylib to: /usr/lib/swift/lib_InternalSwiftSyntaxParser.dylib
RPATH failed expanding     @rpath/lib_InternalSwiftSyntaxParser.dylib to: /Applications/Xcode-11.3.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/lib_InternalSwiftSyntaxParser.dylib
dyld: Library not loaded: @rpath/lib_InternalSwiftSyntaxParser.dylib
  Referenced from: /usr/local/bin/swiftlint

I'm not sure how to fix that and won't have time to look into this until later, so I recommend using 0.38.2 for now.

@nathawes do you have any ideas on how to fix this? Ideally we'd statically link lib_InternalSwiftSyntaxParser, but maybe that's not possible?

This update broke our CI build system.
Currently it's pulling always the last version.
I'm testing a fix by copying the latest Xcode and renaming it to: Xcode-11.3.1.app

FYI
We use autoupdate with HomeBrew to keep our development systems and CI system using the same version of SwiftLint and other tools. If using HomeBrew I recommend using:

brew uninstall swiftlint
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/203436f8567a3b6455264a1d896da5b1df1e50e6/Formula/swiftlint.rb
brew pin swiftlint

This will keep SwiftLint at version 0.38.2 until brew unpin swiftlint is run.

My team is also experiencing this problem on Xcode 11.3.1. We're installing it with CocoaPods as well

@akyrtzi what's the right thing to do here?

[RicardoKoch]

I was able to temporarily fix this issue by renaming Xcode.app to Xcode-11.3.1.app (inside Applications).

[leifktaylor]

This broke my team's CI build.
We resolved the issue for the time being by locking our Swiftlint version to 0.38.2 in our podfile.

brew reinstall --build-from-source swiftlint built a copy of 0.39 for me that works properly, so that's a workaround.
