Can you please find out why my app crashes? When I tap on any of my tab in my tabbars app crashes. It's a rendom issue but generates very frequently. The error message is as follows:
2012-01-18 14:48:50.029 MyApp[2823:f803] *** Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <CALayerArray: 0x6b46bd0> was mutated while being enumerated.'

Usually this is caused by adding / removing objects from a NSMutableArray while it's enumerated. For example:
[array enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[array removeObject:obj];
}];
Check your code whether you are doing something like this.

Realm 5.0.2
I'm trying to understand how this crash is possible. It is crashing when calling first on a Realm Results object. I'm guessing this is a concurrency issue, but Realm is instantiated on same thread as query, and the Realm objects are immediately converted to app objects. But if it's not a concurrency issue, then ... what?!

It looks like you're not the only one with this problem.
https://github.com/realm/realm-cocoa/issues/6556
This looks like a problem with 5.0.x, some have downgraded to 4.x to remove the problem. It references another issue (bottom of the report) which has been fixed and merged, but not yet released.
I'd read the bug report and see if this follows your experience, then either (a) follow the workaround, or (b) downgrade to 4.4.x. Watch the fix issue (https://github.com/realm/realm-core/pull/3828) for being included in a new release.
First I can login with username and password at magento admin than I get this:
this error
There has been an error processing your request
Invalid scope type ''
Nowhere to find this issue
Hopefully someone knows it
What to do?
Website works perfect only backend.
Thanks a Lot

I'm experiencing a crash in TyphoonComponentFactory.m when trying to instantiate an object - this line crashes with EXC_BAD_ACCESS:
279:[pool setObject:instance forKey:definition.key];
Or sometimes this one:
276:id instance = [pool objectForKey:definition.key];
All the variables - pool, instance, definition, look right at the time it crashes, in the debugger. Earlier in the program's execution (but not much earlier, i.e. the same runloop) I've set up my TyphoonComponentFactory and made it the default factory. Is there anything that could be causing this? I had a vague theory that the factory is created too late for the callers but... pretty weak.
Typhoon version 1.8.2. Here's the assembly:
#import "EndpointQueueAssembly.h"
#import "EndpointQueue.h"
#import "URLStorage.h"
#import "EndpointHTTPMethods.h"
#import "EndpointURLStrings.h"

Further update:
It seems like Typhoon is defaulting to TyphoonScopeObjectGraph, which is apparently not thread-safe. We switched all non-singletons to TyphoonScopePrototype, and we now experience crashes in TyphoonCallStack -pop, in line 59, [_storage removeLastObject]. Seems to be an exception of some sort but the debugger doesn't spit anything useful out.
Cannot comment on your post (haven't enough reputation):
Yes, if you create components from different threads - it can be reason of crashes. Typhoon is not threaded-safe now(we are using NSMutableArray, NSMutableDictionary which are not threaded-safe, during object creation).
You can fix it by wrapping Typhoon call into serial queue or synchronized statement.. Or we can do it inside Typhoon (but it will be Typhoon 2.0 feature - hard to maintain two versions at same time)
Update:
Typhoon 2.0 is now thread-safe.
Here's our solution, which seems to work pretty well:
#import "TyphoonComponentFactory+SwizzledObjectForDefinition.h"
#import "JRSwizzle.h"
#implementation TyphoonComponentFactory (SwizzledObjectForDefinition)
+ (void)swizzleMethods
{
SEL objectForDefinitionSelector = sel_registerName("objectForDefinition:");
[TyphoonComponentFactory jr_swizzleMethod: objectForDefinitionSelector
withMethod: #selector(swizzledObjectForDefinition:)
error: nil];
}
// Synchronize objectForDefinition
- (id)swizzledObjectForDefinition:(TyphoonDefinition *)definition
{
#synchronized(self) {
return [self swizzledObjectForDefinition:definition];
}
}
#end
We also declare all scopes as either Singleton or Prototype.
When I call presentRenderBuffer in some situations my app crash with EXC_BAD_ACCESS. But usually all is ok.

Do you have any ideas about this?
SOLVE:
Texture is created and deleted in different contexts. This has caused problems.
Now texture is created and deleted in one context. It has solved the problem.
I get the following error. What do i have to do? Is it something with the Collections or something else?

What do i have to do?
This is the part (line 228) in PDO.php where it refer to:
public function _execute(array $params = null)
{
try {
if ($params !== null) {
return $this->_stmt->execute($params);
} else {
return $this->_stmt->execute();
}
} catch (PDOException $e) {
#require_once 'Zend/Db/Statement/Exception.php';
throw new Zend_Db_Statement_Exception($e->getMessage(), (int) $e->getCode(), $e);
}
}
Thanks
Jeroen
