Xcode 11 beta 4 error: Command CompileSwiftSources failed with a nonzero exit code

问题

I've downloaded the latest Xcode beta 4. When I build I'm getting the same error with 3 of my pods:

Command CompileSwiftSources failed with a nonzero exit code
<unknown>:0: error: unknown argument: '-w'
<unknown>:0: error: unknown argument: '-Xanalyzer'
<unknown>:0: error: unknown argument: '-analyzer-disable-all-checks'

This is the MarqueeLabel pod logs:

I have tried:

Cleaning and deep cleaning (shift + alt + cmd + k)
Deleting the Derived Data folder
Restarting Xcode

I can't see the error listed in the release notes. https://developer.apple.com/documentation/xcode_release_notes/xcode_11_beta_4_release_notes

Does anyone know what the problem is or a workaround?

回答1:

There is a known issue with Cocoapods and Xcode 11 Beta 4 where inhibit_all_warnings! causes arguments to be set for Swift which do not compile. Removing this inhibit resolves the issue, and Swift warnings can be inhibited with SWIFT_SUPPRESS_WARNINGS = YES on targets instead.

回答2:

CocoaPods had a fix for this that got released as part of CocoaPods 1.7.5.

Below is the answer preceding the 1.7.5 release:

_{If you need to use Xcode 11 Beta 4 in the mean time, you could install a patched version of CocoaPods from that pull request:}

_{1. Open Gemfile, replace gem 'cocoapods' with}

gem 'cocoapods', :git => 'https://github.com/dnkoutso/CocoaPods.git', :branch => "swift_compiler_warnings"

_{2. Run bundle install and bundle exec pod install}

_{Keep in mind, this is a temporary solution.}

回答3:

The latest version of CocoaPods (1.7.5) has this issue fixed!

In Terminal run

sudo gem update cocoapods
And then, on your project directory

pod install

Resolved for me!!!!

The issue is actually i created two files with same name. So after i renamed one of a file and error cleared.
