Command Failed Due to Signal: Segmentation Fault: 11

Command failed due to signal: Segmentation fault: 11

For anyone else coming across this... I found the issue was caused by importing a custom framework, I have no idea how to correct it. But simply removing the import and any code referencing items from the framework fixes the issue.

Hope this can save someone a few hours chasing down which line is causing the issue.

Try disabling Swift Compiler Optimization for Release

Then if you get any errors for missing files:

In the file inspector of the file click on the folder icon next to "Location" and locate the file manually

For teamItem.toDictionary, try putting teamItem.toDictionary as Any.

I think these are genuine compiler issues. Try to make smallish changes until it works.

You're force unwrapping local without checking if it's nil, which it may be if you have non-numeric characters.

You either need a default value, or change the method to return nil on failure and and check for nil elsewhere.

var nonZeroNumber:String{
    let local = Double(self) ?? 0       // use 0 if Double(self) was nil
    return String(format: "%.0f",local) // local, not local!
}

or

var nonZeroNumber: String? {    // note Optional
    guard let local = Double(self) else {
        return nil
    }
    return String(format: "%.0f, local) 
}

... 
textField.text = finalStr.nonZeroNumber ?? "default value"
