I had the Illegal instruction 4 problem as many issues out there, but my cause was different from the ones I found and I think there could be a better message accompanying the output.
Complete output when running SwiftLint, including the stack trace and command used
$ ./Pods/SwiftLint/swiftlint lint
Loading configuration from '.swiftlint.yml'
Illegal instruction: 4
Environment
SwiftLint version (run swiftlint version to be sure)?
SwiftLint (0.39.2) [from Podfile.lock]
Installation method used (Homebrew, CocoaPods, building from source, etc)?
CocoaPods

Are you using nested configurations?
If so, paste their relative paths and respective contents.
No.
Which Xcode version are you using (check xcodebuild -version)?
Xcode 11.3
Build version 11C29
Solution
I had a rule listed twich in the disabled_rules list.
I had rules in the disabled_rules list and the opt_in rules list as well.
I removed all of them (commented them in fact) and Swiftlint started working.
Ideally, the message with which Swiftlint fails could be improved to say there are inconsistencies in the yml file.
