Simulator suddenly crashing on DBFileSystem
I'm using the newest IOS SDK for the Sync API. All of a sudden I'm getting a EXE_BAD_ACCESS when trying to assign the DBFileSystem as follows: (crashes on DBFilesystem *filesystem = [[DBFilesystem alloc] initWithAccount:account];). I'm using Xcode 6.1 and both the 71 and 8.1 simulators are crashing.
DBAccountManager *accountMgr =
[[DBAccountManager alloc] initWithAppKey:appKey secret:appSecret];
if (accountMgr) {
[DBAccountManager setSharedManager:accountMgr];
// Set up main linked account
int nAccounts = [[accountMgr linkedAccounts] count];
if (nAccounts > 0) {
DBAccount *account = [[accountMgr linkedAccounts] objectAtIndex:0];
if (account) {
DBFilesystem *filesystem = [[DBFilesystem alloc] initWithAccount:account];
}
}

Can you post the full stack trace/any output?
How do I get a stack trace from the simulator - there don't appear to be any logs ...
The best I know how to do is giving you the current thread info ... and the assembler code from where it fails ...Thread 1Queue : com.apple.main-thread (serial) #0 0x0107ca08 in

Thanks for the additional information! I can't seem to reproduce this here though. Can you make sure you're on the latest version of the SDK (currently 3.1.2):
https://www.dropbox.com/developers/sync/sdks/ios
In addition, make sure you're on the latest version of Xcode (currently 6.1.1).
Also, do the provided sample apps (e.g., "Notes") work for you, or do they also crash like this in the simulator?
Yes to all 3 - I'm using 3.1.2 SDK, 6.1.1 Xcode and the Notes application works fine. Strange - I will keep plugging ...
- Greg-DB
Thanks for confirming those. If you can reproduce this in a simple project that you can share with us so we can reproduce it here that would be very helpful.
I can't seem to duplicate it in another project. However the only other clue I have is that the same project works absolutely fine on my laptop (MacBook Pro running OX X Yosemite 10.10.1). My Mac, also running the same OS, fails. As far as I can tell the environments are the same.
- Greg-DB
Do you know if you were doing anything in particular in that simulator when this started?
Also, have you tried resetting the simulator and seeing if the problem still reproduces? This runs the risk of losing the ability to trigger this of course, but as this can't seem to be reproduced on device or other simulators, it may just be a problem with the simulator itself, or at least a very rare problem.
I usually think of trying the obvious, however in this situation it didn't help. I reset the simulator and I still have the same problem. Sorry for the delay in response - for some reason I am not getting email notifications when this thread is updated ...
- Greg-DB
Thanks! Unfortunately without being able to reproduce this we're not going to be able to fix it. Luckily it's only happening on the simulator (and may in fact be due to or related to the simulator itself) so we don't have to worry about this in the wild, as far as we can tell. If you do see this elsewhere or have more information though, please let us know.
