Log of failed build
Always fails for me. Here's a build log.
I can reproduce it.
This fix will be included in the 7.0.7 release. In the meantime you can either just rebuild when this occurs, or add '-f' to the additional mtouch arguments in the project's iOS Build options (which will force a full rebuild every time).
QA: unit tests have been added as well.
Thank you! Amazingly quick :-)
Does this fix the MT3005+MT3006 warnings too?
No, but those have been fixed in another bug report.
Unit test have been added for this as mentioned in comment#4. Hence changing the status of this issue to Verified.
