Re: Has Apple changed their push certified policy?

[Hunter Hillegas]

Correct, you just need one certificate that will cover both (still need one per 
app though).

There’s also a newer JWT based method that looks even more robust, though I 
haven’t used it personally yet. It’s detailed here:

Apple does provide older versions of macOS that you can download and run in 
something like vmWare or Parallels if you want to try running Xcode 8 - it 
would be interesting to see what happens there. Looks like Xcode 8 will run on 
Sierra which you may be able to get via this link: 
https://itunes.apple.com/gb/app/macos-sierra/id1127487414?mt=12

AppKit and other libraries do often behave slightly differently based on the 
version they are built and run against, to maintain compatibility. So it’s 
possible that a build from Xcode 8 would hit slightly different code paths in 
the frameworks than Xcode 9 or 10.

I’m much more fluent in UIKit than AppKit but I’d be surprised if this was the 
case - would make Core Data faults, one of the best features for dealing with 
large data sets, basically worthless when used with NSTableView.

That said, you could try profiling this in Instruments to see what it’s doing 
in that period of time right before it crashes when it’s burning CPU.

You might get an automated email when a future build is available asking you to

I have many open bugs from years back which usually either means the issue is 
still out there or it was fixed but the screeners didn’t wire up the bug in a 
way that they know my issue was resolved.

Apple has said (Craig F. on The Talk Show recently) that this is a place they

Re: Is CoreData on iOS ready for prime time for serious work?

[Hunter Hillegas]

I've used Core Data a ton in apps since it was introduced on iOS. I've also 
used NSFetchedResultsController quite a bit and I've helped others with their 
Core Data code.

One thing to keep in mind is that Core Data uses exceptions internally as part 
of its normal operation. If you break on exceptions, you'll end up in the 
debugger quite a bit but it's not because anything is broken, just the way Core 
Data is built. Annoying but important to remember. Your customers should not be 
impacted by this at all.

Regarding crashes, by far the most common cause is improper use of Core Data 
and threads/queues. You mentioned using thread confinement - by that I assume 
you mean NSConfinementConcurrencyType and not something like 
NSPrivateQueueConcurrencyType? Have you considered using the newer 
NSPrivateQueueConcurrencyType and the performBlock methods? These enforce the 
threading rules even more explicitly and make it harder to make a mistake. For 
instance, if you init a MOC with thread confinement on the main thread even if 
you only use it on another thread, you're likely breaking the rules (MOCs 
created on the main thread hook into the run loop in special ways - make sure 
you are creating your MOCs on the thread/queue they are going to be used on).

I've done several apps with what sounds like similar use cases and not had 
crashes or other problems so my guess is something may be slightly off… if you 
can use the new stuff, consider it. It's very helpful.

Hope that helps somewhat.

 I just added CoreData to an app I'm working on. I've been working with 
 CoreData for about a year, not exclusively but pretty regularly so I think 
 I'm experienced enough to set it up properly.
 
 However, our testers are experiencing what I feel is more than normal crashes 
 in the main part of the app that depends on CoreData. I'm using an 
 NSFetchedResultsController to drive my main table view and that part seems 
 very weak and will break or raise an exception at any time for any reason. I 
 collecting those crashes that can be detected by TestFlight and there is no 
 relation between them but they all resolve around CoreData or the main 
 tableview.
 
 The heaviest load is when I get a bunch of data from a server that is turned 
 into JSON objects and then saved to the database. There can be 200 pretty 
 large dictionaries coming at once and they are all saved to the database in a 
 serial queue, while at the same time, the fetched results controller sends 
 the usual delegate messages to adds those rows to the table view. I would say 
 that 80% of the time, it works just fine, but for about 20% of the loads, 
 some involved object will raise an exception. Since I'm using multiple 
 threads, and as recommended in the doc, I'm using the thread confinement 
 method to perform the needed operations that involve the database and managed 
 objects. I have one managed object context per thread, but there is really 
 only one, in that serial queue, plus the one in the main thread. I implement 
 the didReceiveManagedObjectContextSaveNotification: methods to merge the 
 changes on the main thread, as recommended. I pass object IDs when I need to 
 access a managed object context from one thread to another.
 
 Still, I feel there are way too many crashes.
 
 I have read from older messages that the fetched results controller could get 
 confused when issuing updates, moves and inserts back in iOS 3 and 4. But I 
 haven't found anything that would lead me to believe that these bugs are 
 still present. But, are they? Is it safe to use this technology for some 
 serious database work?
 
 Any advice, pointer or info would be greatly appreciated.

Re: Core Data fetch performance

[Hunter Hillegas]

Do you have keyShadow set as indexed in the model? If not, you probably want to 
give that a try.

If you have all of the keys up front (i.e. this is a big batch update or insert 
from the Web Service data), you might consider loading all of the records at 
once and then using a predicate to find what you need. Something like:

//load all possible matches at once
NSFetchRequest *possibleEventsFetchRequest = [[NSFetchRequest alloc] 
initWithEntityName:@MissionEvent]; 
[possibleEventsFetchRequest setPredicate:[NSPredicate 
predicateWithFormat:@keyShadow IN %@, allPossibleKeyShadows]];
NSArray *possibleEvents = [self.managedObjectContext executeFetchRequest: 
possibleEventsFetchRequest error:nil];

//create a filter predicate
NSPredicate *indexMatchPredicate = [NSPredicate predicateWithFormat:@keyShadow 
== %ld, inMEP.mId];

//this now happens in memory
NSManagedObject *matchingObject = [[possibleEvents filteredArrayUsingPredicate: 
indexMatchPredicate] lastObject];

 I'm seeing a substantial degradation in Core Data fetch performance after 
 just a few thousand objects, in the simulator on a beefy MacBook Pro.
 
 My app loads data from the web, then uses an integer key in each downloaded 
 record to find the local record in Core Data. So I do a lot of queries like 
 this:
 
 {
NSFetchRequest* req = [[NSFetchRequest alloc] init];
req.fetchLimit = 1;
 
NSManagedObjectContext* moc = self.managedObjectContext;
NSEntityDescription* entity = [NSEntityDescription entityForName: 
 @MissionEvent
  inManagedObjectContext: moc];
req.entity = entity;
 
NSPredicate* pred = [NSPredicate predicateWithFormat: @keyShadow == %ld, 
 inMEP.mId];
req.predicate = pred;
 
NSError*error = nil;
NSArray* events = [self.managedObjectContext executeFetchRequest: req 
 error: error];
...
 }
 
 Basically, I query, the insert, over and over. As the number of records grows 
 from 0 to 6000, the time it takes to execute this query grows from about 
 0.0007 s to about 0.0126 s. Indexing is on for keyShadow:
 
 sqlite explain query plan SELECT 0, t0.Z_PK, t0.Z_OPT, t0.ZCLOCKSHADOW, 
 t0.ZDESC, t0.ZDISABLEDSHADOW, t0.ZDURATIONSHADOW, t0.ZKEYSHADOW, 
 t0.ZLASTMODIFIED, t0.ZNAME, t0.ZSEQUENCESHADOW, t0.ZTIMESHADOW, 
 t0.ZTYPESHADOW, t0.ZMISSION FROM ZMISSIONEVENT t0 WHERE  t0.ZKEYSHADOW = ?
   ... ;
 sele  order  from  deta
   -    
 0 0  0 SEARCH TABLE ZMISSIONEVENT AS t0 USING INDEX 
 ZMISSIONEVENT_ZKEYSHADOW_INDEX (ZKEYSHADOW=?) (~10 rows)
 
 This seems like pretty poor performance. Is this the best I can hope for?
 
 Thanks,

Re: Core Data fetch performance

[Hunter Hillegas]

 Do you have keyShadow set as indexed in the model? If not, you probably want 
 to give that a try.
 
 Yeah, the key is indexed (as I pointed out in the original post :-))

Heh, I re-read your post like four times and only just now saw that notation. 
Whoops.

 If you have all of the keys up front (i.e. this is a big batch update or 
 insert from the Web Service data), you might consider loading all of the 
 records at once and then using a predicate to find what you need. Something 
 like:
 
 I do. I was thinking about this last night. I'm concerned that this may 
 require too much memory, and building a string of 6400 IDs for the query to 
 then format...sounds expensive.

It's possible that doing them all in one hit might be too much… As with most 
workloads, you may need to experiment to find a happy medium.

 Can one build IN queries directly?

I'm not entirely sure I know what you mean by 'directly' in this context.

 I currently download on a separate thread, then call back to the main thread 
 for each record. The intent was avoid doing Core Data work on a separate 
 thread, and keep the UI responsive. But that doesn't really enable the second 
 core, and it adds a lot of overhead. Maybe it's time to do the Core Data on 
 the second thread, too. Pretty sure that will require substantial changes to 
 the way my UI keeps up with updates.

GCD, along with the Core Data changes in iOS 5 and 6 for handling concurrency, 
make this much easier than it used to be (or at least cleaner and harder to 
screw up as badly).

Re: Serious iPhone 4s iCloud issue

[Hunter Hillegas]

The simplest way to see what's in your iCloud account is from a Mac (10.7.2 or 
later).

Go to: ~/Library/Mobile Documents - that's your iCloud 'Documents' storage 
sync'd to your Mac and you can see exactly what is, or isn't there.

There's a method on UIPopoverDelegate that allows you to tell it NOT to dismiss

something like (BOOL)shouldDismissPopover:(UIPopover *)popover

you can use that to make a popover modal.

Re: In App Purchase's SKProductsRequest not working when App is already installed on the device

Are you connecting to the Sandbox environment or production?

I believe you can only connect to Sandbox when launched via Xcode *and* if the

it could cease to be true at any moment, as IAP setup is one sacrificial lamb

Re: Core data fetch and multithreading

[Hunter Hillegas]

I think someone somewhere told me that if you create a MOC on the main thread, 
there's some special runloop integration that is included, hence one of the 
reasons it's important to not create one on the main thread and then pass it 
around.

This is also important to keep in mind re: NSOperation, since it's init is 
called on the main thread.

 I think maybe you have more design options here. For example, you can [in

 safe, and you already have [I think] the perfect mechanism for that: GCD. 
 You'd probably also want to break down your background operations so that 
 enumeration of the relationship doesn't take place within a single GCD block 
 execution, but where each block execution is one iteration of the 
 enumeration. (Isn't that more GCD-like anyway?)

To-Many/To-Many Master/Detail Core Data / Bindings Question

[Hunter Hillegas]

Howdy,

Trying to crank out a real Cocoa app as an experiment - usually spend my time 
doing Cocoa Touch.

Anyway, I have a pretty simple set of models:

Accounts-Items

I want to setup a screen with a table of accounts. When you click on an 
account, you see a table of items, click on an item, see it's detail. Simple.

My question is if I can do this all with bindings. The table of accounts works 
fine. What I can't seem to figure out is how to limit the 'Items' in the second 
NSTableView to just be the ones associated with the selected account, using 
bindings.

Is there a way to do so? I see I can set a fetch predicate for the 
NSArrayController that is controlling the items but I'm not sure how to 
reference the selected account in the 'account' table view to limit the 
contents of the second NSTableView - if that's even possible... Or 
alternatively, just have the items NSTableView show entities that are in the 
'items' relationship of the selected account. Seems like a pretty simple use 
case but I'm missing the magic.

I can see a path by subclassing NSArrayController but I was hoping to do it all 
with bindings if I could - I just don't know enough to know which way to go or 
if I should just break out the code.

Any help appreciated.

Cheers,
Hunter___

I did read this page - but I'm not sure it does what I want because it's only

Does that make more sense?

 If I understand your question correctly, the usual way is to bind the detail 
 NSArrayController's content via the master NSArrayController's selection 
 property. See:

Re: To-Many/To-Many Master/Detail Core Data / Bindings Question

Yes, that's exactly it. Dual level master detail.

For whatever reason, the part I just couldn't see in my head was how to wire up 
the second NSArrayController to accountsController.selection.items.

Thank you so much - just needed that little kick to get to the next step. 
Appreciate it.

 Actually, your items are the *detail* for the account, and then possibly the 
 master for another detail interface.
 
 So, let's say you have a NSTableView listing accounts, a second NSTableView 
 listing items in the accounts list's selection, and a set of text fields, etc 
 showing more details of the item(s) selected in the item list.
 
 The accounts list uses a NSArrayController whose content is bound to the 
 accounts (array if not Core Data, set if Core Data) in your data model.
 
 Columns in your accounts list would be bound to 
 accountsController.arrangedObjects.whateverAccountProperty.
 
 The items list uses a second NSArrayController whose content is bound to 
 accountsController.selection.items. This represents the items in the selected 
 account, or possibly in the selected accounts. (In NSControllerland, there's 
 really no distinction between a single object or multiple objects, until 
 later in the process -- each eventual UI element deals with the problem of 
 how to display multiple items. There's also an option somewhere that controls 
 how the items are merged if there are multiple selected accounts, but if your 
 items are unique to an account, the result would be the same.)
 
 Columns in your items list would be bound to 
 itemsController.arrangedObjects.whateverItemProperty.
 
 Item detail elements like text fields -- if you want them -- would be bound 
 to itemsController.selection.whateverItemProperty. Such user interface 
 elements would then display the value of the item selected in the items list. 
 If there are multiple items selected, then the binding options for multiple 
 values selections kick in.
 
 So your interface is not so much master-master-detail as dual-level 
 master-detail.
 
 There's probably an alternative way of approaching this, by programmatically 
 maintaining a fetch request for the items array controller, based on 
 monitoring the selection of the account array controller, but I can't think 
 of any obvious way to do this without writing code. (A few lines of code, but 
 code nevertheless.) Chaining array controllers, and using the arrangedObjects 
 or selection properties as appropriate, should allow you to design the 
 interface codelessly.
 
 Does that sound like what you need? There was a different tutorial that 
 explored some of this, but I can't find it any more.
