Xcode error: Abort Trap 6

I've seen this abort as the result of an unhandled C++ exception. Since you seem to playing around with parts of Swift, parts of which are written in C++ (the SIL support specifically), it looks like you've tripped over an unhandled exception. Note that this is based on my experience building software with C++ on Mac platforms.

The only thing I deal with is Swift, not C++. Tbh, I have no clue what this error means. It comes and goes occassionally. I have to clean the project, switch to another simulator or switch from the Xcode 10 Beta stable Xcode version to the current stable version of Xcode. I'm just lost with this error.

Are you seeing this message while building your app? Or while running it on the device / simulator?

I'm seeing this message while building my app and when I try to run on device or simulator. With Xcode 10 beta 5 worked perfectly.

I'm seeing this message while building my app and when I try to run on device or simulator.

I’m sorry that my question wasn’t more clear. What I need to know is whether you see this during the build of your app? Or whether you see it at runtime? A good diagnostic test is as follows:

1. Open your project and select the appropriate scheme.

2. Choose Product > Build. Do you see the error? If you do, stop now.

3. If not, choose Product > Perform Action > Run Without Building. Do you see the error now?

I have the same problem. Have you got the solution.

Can you respond to the query in my 6 Sep post?

The info you posted on 21 Sep indicates that the Swift compiler is crashing while trying to compile your project. That should never happen and is always bugworthy. Please file a bug about this, preferably including a project that reproduces the problem. I’d appreciate you posting your bug number here, just for the record.

As far as getting your project building is concerned, I have a couple of questions:

• If you create a new project from the built-in templates, does it build?

• If you (temporarily, just for testing) create a new user and log is as that user, is that user able to build your project?

My project was working fine in xcode 9.*, I am using swift 4, In xode 10 it is giving compilation error "Abort Trap 6"

Please find Log below:

Running pass 'Module Verifier' on function '@"$S10Momspresso16SearchResultCellC05setupD03foryyXl_tFAA09TableViewD0CAdEyyXlSg_tFTV"'

error: Abort trap: 6

I'm having the same problem

The compiler crashes with an "Abort trap: 6" while Archiving the project

However it compiles and runs without any issues on the simulator!

Config:

Xcode 10 (10A255)

MacOS 10.13.6

I still haven't solved the problem.

If I create a new project it build successful.

I think it just heppen on my project. Of course, not only mine, but also those of my workmates.

How can I report my project to you?

Thanks for your reply

Facing the same issue. Is this something to do with Xcode 10.* ?

You seem to be the person on this thread who knows the most. As they say, no good deed goes unpunished. I'm getting an abort trap 6 on my build as well. Specifically:

1. Running pass 'Module Verifier' on function '@"$S8DTGenomeAAC10testGenomeyyF"'
error: Abort trap: 6

I'm trying to build my unit test. My test class is DTGenome, and the only function in it is testGenome().

It has been building just fine all day, but it suddenly started choking. At first it was saying the name of one of my protocols. I made a few different random changes to the protocol, like private to public, or changing the name of one of the functions in the protocol, just random stuff. The abort would come and go with some of these changes. I got it to go away, but now it's back. I tried your idea of putting the code into a new project, and that fails too.

I've filed a bug report: 48047205. Cheers

Facing the same issue with Xcode 10+

I have the same issue, when trying to build my App. I converted the project from Swift 3 to 4.2. All submodules to build only my project failes.

error: Abort trap: 6

I managed to get rid of the eorror:

Solution 1: go to Build settings an choose compilation mode 'Whole Module' instead of 'Incremental' - I'm not sure if this solution is always a good choice.

Solution 2: When using Xcode 10.2, with Swift 4.2 I got the above error all the time. Go to Swift.org, download latest Swift 4.2.3 Toolchain for Xcode and install it. Go the Menu and select Toolchain 4.2.3 -> voila my issue was got.

But now I'm not able to do Swift 5 migration - looks like the the Xcode default toolchain gets used.

I updated to Xcode 10.2.1 but still the same issue.

I was facing the same problem in Xcode 10.2.1.

After days trying to solve it, I discovered that in my case this error was caused by a Swift class that inherits an Objective-C Third Party class (more specifically the

FSCalendarCell

I rewrote the Swift class for Objective-C and it compiled and ran without any issues.

I was using cocoapods, and this line was commented

use_frameworks!

So I did uncomment, updated the pods, cleaned and it worked

in my case, I found below code in the XXXBridgingHearder.h file

```

#import "OtherClassName.h" <- in this file, import "ClassA.h"

#import "Module/ClassA.h"

```

This module is a cocoapods dynamic lib. There is a swift ClassB inherit a OC ClassA in this module. It also encounter another error: MyClass is unavailable: cannot find Swift declaration for this class.

It really spend me a lot time to find out the issue.

Hope it can help.

I'm using Xcode 12.4. After making some changes to a class (to be precise, I changed the data type of a function argument), I ran into this problem. I've never faced this error before. Doing a clean (Product -> Clean) helped me resolve this problem. Hope this helps someone.

I've got the same error. The reason was here : guard let cell = cell { else return UITableViewCell } inside cellForRowAt method. After when i changed that "let cell" to "let currentCell" everything builds fine. I guess you should check if you have similar cases. Hope it will helps
