SwiftLint: illegal instruction: 4 swiftlint on Xcode 11

New Issue Checklist

Updated SwiftLint to the latest version
I searched for existing GitHub issues

Describe the bug

On beta 2 everything worked fine, but on Xcode 11 beta 3 swiftlint starts failing with illegal instruction: 4 swiftlint

SwiftLint.build/Script-77CC59392189ADCC00127275.sh: line 9: 34044 Illegal instruction: 4  swiftlint

After commenting opt in rules one by one found that it was because of reduce_into and trailing_closure rules

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

$ swiftlint lint

I’m still seeing it with 11.3.1, default toolchain

Xcode 11 GM with 0.34.0 works for me. But have the same issue with 0.35.0 😢 Will waiting for the new update …

Same issue with Xcode 11 Beta 7. Disabling no_space_in_method_call helps.

It fails in raw strings with properties inside interpolation.

import XCTest

final class Class: XCTestCase {
    func testA() {
        let data = Data(#"{"status":100, "code":\#(a.code), "message": "failure"}"#.utf8)
    }
}

Thanks for sharing! Turns out that even though the fix https://github.com/apple/swift/pull/27186 was included in the swift-5.1-branch before its version was set to 5.1.1, the fix hasn’t actually made it into Xcode’s Swift toolchains for 5.1.1 or 5.1.2 😞.

You can work around this by using the latest Swift 5.1 OSS toolchain:

git clone https://github.com/broadwaylamb/OpenCombine.git swiftlint-crash
cd swiftlint-crash
git checkout 806ea79d672c58ef53a79df1e01253332e7af5c6
TOOLCHAIN_DIR=/Library/Developer/Toolchains/swift-5.1-DEVELOPMENT-SNAPSHOT-2019-11-05-a.xctoolchain swiftlint

I’m still getting this with Swift 5.1.2 (Xcode 11.2) and SwiftLint 0.36.0.

This advice https://github.com/realm/SwiftLint/issues/2793#issuecomment-529342828 helps.

I’m also hitting this issue on Xcode 11.1. Not sure what file it’s happening on because if I lint just the last file it succeeds.

Looks like a fix was pushed to the Swift compiler (https://github.com/apple/swift/pull/26354), but it’s unclear when it’ll be on official toolchains.

Same issue in new rule no_space_in_method_call in 0.35. Screenshot 2019-09-06 at 17 40 37

Thanks for sharing steps to reproduce! I have a fix in progress here: https://github.com/jpsim/SourceKitten/pull/602
