Description Mike Norman 2015-11-06 15:48:52 UTC
I'm on 5.11, but I've seen this on 5.10, as well.

Repro:
1) Create a new Single-View app.
2) Open storyboard in designer.
3) Lovingly and painstakingly craft a complicated UI with a bunch of constraints.
4) Select a widget, and click it to switch to constraints mode.
5) Click the "x" to the right of "CONSTRAINTS" in the designer ("Remove existing constraints").

Expected:
The constraints go away, and the widget remains.

Actual:
Randomly: BOOM. Widget gone.

Notes:
I know, Heisenbug. I hope this repros and can be tracked down.

When this issue happens can you attach the log files from XS in case there's anything interesting there?
Comment 2 Alan McGovern 2015-11-11 12:25:48 UTC
From your description i don't think this is a duplicate of bug 35641. However i wouldn't mind if you can double check with the latest master builds because the fix for bug 35641 landed and if it makes this problem go away, that'd be great!
Comment 3 Mike Norman 2015-11-12 12:41:48 UTC
I'm unable to repro on the latest RC. I'll leave it to you, Alan, to mark it Not Repro if you think we're out of the woods.
Comment 4 Alan McGovern 2015-11-12 14:13:44 UTC
If we don't have a solid repro for this then it's as likely to be bug 35641 as it is anything else. That bug would've made it look like widgets were vanishing when you closed a storyboard and re-opened it.

We'll just close this as a dupe unless more information surfaces showing it's actually something else.
