EXC_BAD_ACCESS on XCode 11.2 and iOS13.2 #150

Closed mrommel closed 5 years ago

mrommel commented 5 years ago

Hi, I have issues since I updated my project to XCode 11.2 and iOS13.2.

EXC_BAD_ACCESS when trying to run "Note" Sample on Simulator or Device.

Can anyone help?

I have uploaded a minimal Sample. Lib is included via SPM. Doesn't matter which version (I tried 0.7.0, 0.8.0 and 0.9.0): https://github.com/mrommel/XMLCoderiOS13_2

Bad Access happens in XMLKeyedDecodingContainer.swift:37

self.decoder = decoder
container.withShared { <===== here
  $0.elements = .init($0.elements.map { (decoder.keyTransform($0), $1) })
  $0.attributes = .init($0.attributes.map { (decoder.keyTransform($0), $1) })
}

Try disabling dead code stripping on your app’s project: DEAD_CODE_STRIPPING = NO

For additional context, see the underlying bug here: https://bugs.swift.org/browse/SR-11564

Sorry for not thinking this far - thanks a thousand times.
