    <p>I've recently had a crash concerning a selector not being found when a notification was posted using NSNotificationCenter. What can be causing this error?</p> <p>I've noticed that there was no user code being called after the notification was posted, so that doesn't seem to be a problem on the receiving side of the notification. However, what could cause NSNotificationCenter to crash?</p> <p>Here's the stack trace of the call:</p> <pre><code>0 libSystem.B.dylib 0x00078ac8 __kill + 8 1 libSystem.B.dylib 0x00078ab8 kill + 4 2 libSystem.B.dylib 0x00078aaa raise + 10 3 libSystem.B.dylib 0x0008d03a abort + 50 4 libstdc++.6.dylib 0x00044a20 __gnu_cxx::__verbose_terminate_handler() + 376 5 libobjc.A.dylib 0x00005958 _objc_terminate + 104 6 libstdc++.6.dylib 0x00042df2 __cxxabiv1::__terminate(void (*)()) + 46 7 libstdc++.6.dylib 0x00042e46 std::terminate() + 10 8 libstdc++.6.dylib 0x00042f16 __cxa_throw + 78 9 libobjc.A.dylib 0x00004838 objc_exception_throw + 64 10 CoreFoundation 0x000a167c -[NSObject(NSObject) doesNotRecognizeSelector:] + 96 11 CoreFoundation 0x000491d2 ___forwarding___ + 502 12 CoreFoundation 0x00048f88 _CF_forwarding_prep_0 + 40 13 Foundation 0x000146ac _nsnote_callback + 136 14 CoreFoundation 0x0002670c __CFXNotificationPost_old + 396 15 CoreFoundation 0x000263ac _CFXNotificationPostNotification + 112 16 Foundation 0x0000b014 -[NSNotificationCenter postNotification:] + 132 17 [My Application] 0x000a5ad2 -[PortfolioUpdateOperation main] (PortfolioUpdateOperation.m:37) 18 Foundation 0x0000e9e8 -[__NSOperationInternal start] + 652 19 Foundation 0x0000e74c -[NSOperation start] + 16 20 Foundation 0x00023574 ____startOperations_block_invoke_2 + 40 21 libSystem.B.dylib 0x000d597c _dispatch_call_block_and_release + 12 22 libSystem.B.dylib 0x000d675c _dispatch_worker_thread2 + 120 23 libSystem.B.dylib 0x0007a67a _pthread_wqthread + 258 24 libSystem.B.dylib 0x00073190 start_wqthread + 0 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
