I had the same problem.
My solution was to rename the 'myApp'-directory to 'myAppmyApp' and then I ran the app again. A new 'myApp'-directory was made a the app did run very well again on my iPhone.

A difference with your situation might be this: the name of my app, let's say 'myApp' in the directory 'DerivedData' was myApp concatenated with: '-'

Maybe this will help you.

You can also get this problem, if you have the scenario of your container app's code is Swift 2.3 and you're creating a new extension in Xcode 8.

To solve the above scenario... 

Note: All code has to be in the same swift (compatible) version to compile without failure. 

That being said, one way you could solve this problem is by sticking to Swift 2.3 and then setting your Extension Target's Use Legacy Swift Language Version to "Yes".

You can find that option while Xcode 8 is open as follows:

<ol>
<li>Select your app project root in the Project Navigator (on the left-hand side)</li>
<li>On the right-hand side, select your extension under the TARGETS
section</li>
<li>Once the extension is selected, click on the Build Settings tab</li>
<li>Scroll down and find Use Legacy Swift Language Version﻿ and set it
to Yes from its drop-down menu.</li>
<li>You can now build the project</li>
</ol>

Note: You might need to fix the overridden code in the extension templates since they were originally in Swift 3.

Before doing anything...

(If you can use Xcode 8.0-compatible with your project)

By default your project is set to Xcode 3.2-compatible

<ul>
<li>Select your app project in the Navigator (on the left-hand side)</li>
<li>Select Project Document in the Utilities Panel (on the
right-hand side)</li>
<li>Change Project Format to Xcode 8.0-compatible</li>
</ul>

Try to build your project.

If it doesn't work, try the other solutions proposed.

Note:You can even switch back to Xcode 3.2-compatible after fixing the error and it should work, but you "might" have other build problems later.

Recommendation:
Before debugging an existing project. Close your project and zip a copy of your project file if you did not create a Git repository when you created your project.

I had the same error message after adding a Swift 3 version of a framework. 

My target <code>framework search path</code> was still configured to find both swift 2 and swift 3 version of the same framework, so my project got stuck on swift 2.3 version. 

For me, the solution has been to remove the old framework from my project directory and delete its folder reference from the <code>framework search path</code>.

I fixed this by deleting the embedded binaries in the project. To do this:

<ol>
<li>Open your workspace/ project in Xcode.</li>
<li>Navigate to the actual project file (with the General, Capabilities, etc. ribbon).</li>
<li>Go to General > Embedded Binaries, remove by selecting on the ones you don't want and then clicking the minus sign.</li>
</ol>

Note 1: You shouldn't have to delete them from the "Linked Frameworks and Libraries" section (they should automatically be removed when you remove them from the "Embedded Binaries").

Note 2: I have a lot of dependencies and am using CocoaPods. I have nothing in the "Embedded Binaries" and only the "Pods_[YourApplicationName].framework" in the "Linked Frameworks and Libraries" section.

So I just post the solution I found so far after an hour debugging.

Since Xcode 9, this can be tracked by the compiler log.

If you scroll down to the bottom of the compiler log, you will find this issue is caused by type checking crash.

Just had this pop up after upgrading to Xcode 10.2 ... one of my pods uses Swift.
Fix was to: 

<pre><code>pod repo update

With new <code>Xcode 8 beta 4</code> we started experiencing the following error during <code>CopySwiftLibs</code> build phase:

<pre><code>Effective srcDirs: {(

</code></pre>

error: The following binaries use incompatible versions of Swift:

<blockquote>
 /Users/user/Projects/git/iphone-swift-1/DerivedData/myApp/Build/Products/Debug-iphonesimulator/myApp.app/myApp
 
 /Users/user/Projects/git/iphone-swift-1/myApp/myAppApi.framework/myAppApi
</blockquote>

myAppApi is a subproject in the workspace that contains some shared code (it uses <code>Alamofire</code>).

One thing to note: originally we converted project from Swift 2.2 to Swift 2.3, and then manually upgraded to 3.0.

Does anyone have any idea what might be causing this error?

Thanks!
