you can follow this steps...

<ol>
<li>Make sure to change Swift version to your current version.</li>
<li>Update all your pods.</li>
<li>Clean all derived data of Xcode.</li>
<li>Now Restart your Mac.</li>
</ol>

You are getting all those error's just because of pods..so either you need to update every pod that you are using.

blocks|key|208885|text|因此，当我将我的项目更新到Swift+5时也遇到了同样的问题。出于某种原因，Cocoapods+(最新版本，1.6.1)将一些pods的SWIFT_VERSION设置为Swift+5，即使它们发布为Swift+4，4.1，4.2+pods。因此，我不得不添加一个安装后脚本，如下所示设置swift的校正版本|type|unstyled|depth|inlineStyleRanges|entityRanges|data|208886|post_install+do+%7Cinstaller%7C
++installer.pods_project.targets.each+do+%7Ctarget%7C

So I had same issue when updating my project to Swift 5. 
For some reason, Cocoapods (latest version, 1.6.1) set the SWIFT_VERSION of some pods to Swift 5 even if they're released as Swift 4, 4.1, 4.2 pods. 
So I had to add a post install script that set the correction version of swift like so

<pre><code>post_install do |installer|
 installer.pods_project.targets.each do |target|
 if target.name == 'CryptoSwift' || target.name == 'SwiftyBeaver'
 target.build_configurations.each do |config|
 config.build_settings['SWIFT_VERSION'] = '4.2'
 end
 end
 end
end
</code></pre>

blocks|key|2120780|text|我修复了这个问题，进入Pods项目，然后进入构建设置，并将编译模式设置为Incremental++Release。然后清理和归档，应该可以编译好了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2120781|entityMap^0|B|6|T|4|10|B|1D|P|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

I fixed this issue by going Pods Project then to the building settings and setting Compilation Mode to Incremental for Release. Then clean and archive, should compile fine then.

I had the same issue after upgrading to Xcode 10.2. After following the steps below it worked for me:

<ol>
<li>Update pods</li>
<li>Clean project folder</li>
<li>Change Pods project's Swift Language Version to Unspecified and (as suggested by @Neil Faulkner) Compilation Mode to Incremental </li>
</ol>

blocks|key|208923|text|对于我的项目，问题与pod+Cache有关，当Release的Optimization+Level设置为Optimize+for+Speed+[-O]时，它会给出错误。我再次将Compilation+Mode设置为Whole+Module，并在pod文件中为pod设置了优化级别：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|208924|post_install+do+%7Cinstaller%7C

For my project problem was related to pod <code>Cache</code> which gives error when <code>Optimization Level</code> for <code>Release</code> is set to <code>Optimize for Speed [-O]</code>. I have set <code>Compilation Mode</code> to <code>Whole Module</code> again and set optimization level for the pod in pod file:

<pre><code>post_install do |installer|
 installer.pods_project.targets.each do |target|
 # Cache pod does not accept optimization level '-O', causing Bus 10 error. Use '-Osize' or '-Onone'
 if target.name == 'Cache'
 target.build_configurations.each do |config|
 level = '-Osize'
 config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = level
 puts "Set #{target.name} #{config.name} to Optimization Level #{level}"
 end
 end
 end
end
</code></pre>

blocks|key|2997151|text|我不得不将"Swift编译器-代码生成“中的”优化级别“设置为”发布“--从”优化速度“到”无优化-Onone“，以使缓存通过归档。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2997152|与SwiftyBeaver相同|2997153|这似乎是一个与Xcode10.2相关的问题。此外，其他pod项目似乎也可以进行优化，比如Toucan或XCGLogger。|2997154|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I had to set "Optimization Level" in "Swift Compiler - Code Generation" to "Release" - "No Optimization [-Onone]" from "Optimize for speed" to make Cache pass Archive.

Same with SwiftyBeaver

It seems a problem related to Xcode 10.2. Also other pod projects seems to be fine with Optimization, like Toucan or XCGLogger.

blocks|key|2120845|text|在我的例子中，它只是出现了，可能是因为我在项目构建过程中再次运行了项目。所以我所做的不仅是清理，而且还清理了我的项目|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2120846|SHITF+%2B+ALT+%2B+COMMAND++%2B+K+|code-block|syntax|javascript|2120847|此外，我删除了派生数据，项目重新启动并运行。|2120848|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In my case it just appeared probably because I ran project again while it was building. 
So what I did was not only clean but also folder clean my project using 

<pre><code>SHITF + ALT + COMMAND + K 
</code></pre>

also I deleted derived data and the project was up and running again.

I'm using Xcode 10.2, Swift 5.

With Debug scheme, no issue happens, but with Release scheme when I build or archive, it shows Command compileSwift failed with a nonzero exit code. 

I've tried delete DerivedData / Clean / pod deintegrate &amp; pod install &amp; pod update. None of these works.
