I got error abort trap 6 after I update xcode 9.3 to 10.1

As the title mentioned, I got 'error abort trap 6' after I update xcode 9.3 to 10.1 then compile the Project. The Detail report is in the file.txt.

I had upgraded my code from swift3.0 to swift 4.2, and got the error again.

What's wrong with that?

2. While deserializing SIL function "$S10MyProject28Record_SearchSelectTagButtonC5coderACSgSo7NSCoderC_tcfC"

error: Abort trap: 6

This indicates that the Swift compiler itself has crashed. That should never happen, and so this is most definitely bugworthy.

Please post your bug number, just for the record.

IMPORTANT In cases like this you should always file a bug, but it really helps if you can include a project that reproduces the problem. Ideally this project would be as small as possible. One option here is to make a copy of your main project and then rip stuff out until the compiler stops crashing. This helps in two ways. First, you get your test project for the bug report. Second, this process helps you uncover what triggers the crash, and you can use that to avoid it.

With regards this last point, the log you posted contains this line:

2. While deserializing SIL function "$S10MyProject28Record_SearchSelectTagButtonC5coderACSgSo7NSCoderC_tcfC"

indicating that the crash is probably related to the referenced function. The function’s name has been mangled, but you can still pull clues from it:

• The module name is

  MyProject

• The start of the function name is

  Record_SearchSelectTagButton

I doubt that could be enough in your case, but did you do a Clean Build Folder ?

did you do a Clean Build Folder ?

Yeah, that’s great advice. I make the mistake of assuming that folks know this, but that’s not always the case )-:

Sorry for late.

(obviously 'clean build folder' made no sense)

We chosed a special way to solve the problem, we created a new Project and the name of the Proeject was modified. Then the project build successed.

But if the name is same to the old one 'MyProject', then we would get 'abort trap 6'

the error mentioned Record_SearchSelectTagButton class is a normal button. And when I deleted that class, another error of another view would appear.

class Record_SearchSelectTagButton: UIButton {

override var isSelected: Bool {

didSet {

if isSelected {

self.backgroundColor = MAIN_COLOR

} else {

self.backgroundColor = .white

}

}

}

override init(frame: CGRect) {

super.init(frame: frame)

setTitleColor(COLOR_6, for: .normal)

setTitleColor(.white, for: .selected)

titleLabel?.font = UIFont.systemFont(ofSize: 15)

layer.borderWidth = 0.5

layer.borderColor = COLOR_220.cgColor

layer.cornerRadius = 3.0

}

required init?(coder aDecoder: NSCoder) {

fatalError("init(coder:) has not been implemented")

}

}

I would not want to propose you something that obviously makes no sense. But you will certainly find the answer by yourself 😉

Hi, I got "Abort trap: 6" error using Xcode 12.5.1

I know this is a bit late, but here it is.... I managed to narrow it down to a single line of code:

guard let scnNode = scnNode else { return nil }

I'm using "guard let" wrong, but this was the culprit.

Problem: Abort Trap (In my case my code is working perfectly but when I trying to make an Archive for upload app on testFlight file I got the "Abort Trap")

Solution:- Just Select Your Project from project Navegater (most Left Pane) Select Project > Select Targets > Build Settings > Swift Compiler - Code Genration > Optimization Level > Debug and Realease make "No Optimization [-Onone]"
