Application Crash when calling addFormSection()

[markGilchristBookingBug]

I am getting a crash when calling addFormSection(aSection)

here is the stacktrace

here is my podfile code

     ..
      pod 'XLForm',     '~> 3.2'
    ...

here is my swift code

   let form = XLFormDescriptor()

    let importSection = XLFormSectionDescriptor()
    importSection.addFormRow(
        XLFormRowDescriptor(tag: "import", rowType: XLFormRowDescriptorTypeButton, title: "test")
    )
    form.addFormSection(importSection)

I am using XlForm in 5 other apps and this doesn't happen, any ideas what I may have done wrong?

That is strange. Your code works for me. The issue must be elsewhere. Are you sure it comes from that line?

@mats-claassen yes I am sure it is that line, what makes it even stranger is that this doesn't happen for 4 other projects using xlform! I am lost as to why this could happen
