Hello, are you consistently getting this exception with this version only?

[plu]

Yes. It started when we updated to Xcode 8.3.2.

[bluk]

2.17.0 should fix this issue. If not, please leave a comment and if you can tell if this only occurs in UI tests, if there are any non-normal linker settings (e.g. Swift whole module optimization), or any other details. Thanks.

Thank you for the quick fix, 2.17.0 does fix the issue for us!
