So we have spent the last ~3 weeks creating workarounds for bugs that were found during testing against iOS 11 beta 1.
Today I had to go in and undo all the merges because as of beta 7 Apple have fixed the issues we were seeing.
Weeks of effort wasted that could have been spent upskilling or fixing build issues with an app that will have a release due in the coming weeks and we currently know little about.

Not sure what your point is... If its labelled as beta you have to expect bugs.

@Jonnyforgotten Totally agree. Thats kinda my point. Our QA person tested the apps against beta 1 and raised a bunch of issues which we were told to treat as high priority. But by beta 7 the issues were no longer present and we had to revert 2-3 weeks worth of work. My point is we shouldnt have jumped straight into fixing the issues when the first beta is always so unstable. Should have waited until at least 4 or 5 before considering fixing the issues, and retested the issues against every subsequent beta release.

Ah right sorry I see what you are saying now.
