when archive I get the following error

Hi,
same issue here:

2.	While running pass #1 SILModuleTransform "PerformanceSILLinker".
3.	While deserializing SIL vtable for 'BarcodeScannerViewController' in module 'BarcodeScanner'
error: Abort trap: 6

Any suggestion?

[ahmed-sal]

@GiulioCinelli were you able to find a solution? I have a similar issue

[CinGiu]

@ahmed-sal i think it could be releated to swift version between project (my was in swift 3.3) and library (swift 4).

i'm trying to convert the plugin into a swift 3 lib but i'm not sure that this can be helpfull

[CinGiu]

@ahmed-sal I've solved by disabling Optimization for release in my project

Not sure it can be a real fix but it works

[ahmed-sal]

@GiulioCinelli you are correct.

In order to archive, I needed to remove the pods that are not Swift 4+ and simply replaced them with alternatives or wrote my own libraries. Tedious but it worked.
