sharedApplication is unavailable
I'm trying to access my core data from the watch kit extension but i'm unable to use the shared application because it's not available in watch kit. How do I initialize the managedObjectContextwithin my view controller without using the shared application code?if (self.managedObjectContext_ == nil) { self.managedObjectContext_ = [(AppDelegate *)[[UIApplication sharedApplication] delegate] managedObjectContext]; }right now, it's assuming my managedObjectContext is nil.How do I initialize core data outside my app delegate in the watchkit controllers?

Reply to CoreLocation: startUpdateLocation is unavailable
I looked at using requestLocation but as that only performs one request rather than continous requests I was hoping there would be another way as I share the code for both the iPhone and Watch app.I use a distance filter that only gives me locations when I've moved a certain distance which is really convenient so I guess I need to implement a similar setup for the watch, or as suggested above keep location functionality on the phone.

Reply to Get rid of Open Directory!
I'm stuck here on 2009 Xserve's that need to go, but really no options these days. I wish Apple would have kept OSX and OS X Server seperate and then made OS X Server allowed to be installed on PC hardware under VMWare. All of our servers have been on VMWare now for years and now they are trying to push our clients to that as well with zero clients. Little dangerous for me as they are trying to get rid of the Macs in the process, but it woud be nice to be able to use OS X Server on non mac hardware or bring out server grade hardware again. I always wanted a 3U or so Xserve with atleast 8 Drives in it.

Reply to Can I install back to iOS 8.3 after trying out iOS 9 beta?
I tried to downgrade because i have to send my iphone off to Apple due to a fauty screen, but it fails half way through teh usuaul process. It say the phone failed to restore and then tries to download 8.3 again (even though i've jut told it to instal that a few minutes beofre hand). From previous betas this hasnt been a problem. UPS are due in 1/2 hour to pick up the phone so this is a bit of a problem!Legally speking I fail to see how Apple can void a legal gaurantee for a hardware defect because i put an authorised developer release on via a dev account etc on, but I really dont want them to have to recieve a phone with a dev release on and then refuse it!W

Reply to unable to wake from sleep
I found my iMac struggling to wake up. I waited, and it eventually did. I found a process, sdmd had eaten all the memory. After a reboot (Which took a while!), it now seems to be fine, and this process hasn't run away with the memory again.I suspect it's some form of indexing daemon that isn't properly optimised yet.

Reply to almost afraid to ask on new background modes.
You absolutely have to file enhancement requests and bug reports making your case for the features that you want that iOS doesn't yet support. You probably won't get any direct feedback unless there's difficulty understanding something in your report, but it's still necessary.On the other hand, it's important to remember that Apple applications have both a longer leash (Apple makes the rules) and a shorter leash (Apple's going to be more conservative about most things). The complication with doing a specific task that lasts less than 10 seconds at a specific date and time in the future is one of managing when a dozen different applications all want to do something at the same time. Who goes first? How much time do the have? How does the user tell what's going on? If the foreground application is hogging resources, do you launch late? What happens when you crash in the background?

Reply to The core Idea Of Metal
Yes.A central focus of Metal is to dramatically reduce the CPU cost of common operations. However, it is still quite possible for wasteful code to blow out the CPU cost and end up running slowly and eating up a bunch of battery life. That is, even though the CPU and GPU can run concurrently, your GPU frames can't cycle any faster than the CPU workload required to encode / enqueue them. Thus, quite a lot of making Metal go fast can be making sure that your CPU workload isn't consuming all your time. For me, the CPU cost is usually around 10% or less of the GPU time in well behaved code. If you are running more than that, then you may need to spend some time finding out why.Most of the time, it comes down to object reuse. It is maybe the key way to improve Metal performance. Much of Metal is designed around the assumption that you will allocate expensive resources (textures, buffers, shaders, queues) up front and then reuse them. As an application writer, this is fairly simple, since you should know in advance

Software Documentation - A Standard
I know that there are no set standards or rules for software docuemntation. I am not sure if this is good or bad? I am busy creating my first Software Document for my organisations solution. Our solution is pretty standard. It is a mobile application for iPhone, iPad, Apple Watch and Android [Not sure if im allowed to say that here]. The docuemnt is not a user manual but an internal document which will explain the architechture, lifecyle, deployemnt procedures etc. I have scoured the net looking for resources on best practice, templates, examples and the like. I was wondering if I have missed something but I cant find any sort of standard or commonly defined structure for these documents. It seems to be a company by company type approach with each company writing the document in a way they feel is best.I hope I am wrong. Can anyone shed some light?Thank you very much indeed. I must also appologise in advance if I put this request for information in the wrong place. I dont see an applicaple (

Answer to Java SE 6 problem for El Capitan
Hello! I have searched around the web for finding a solution to the Java SE 6 Runtime that cannot be installed and doesn't allow apps to work as suppose. So while searching the web I found different articles about uninstalling it and deleting the newer version...ect. Nothing worked so I thought what if you go the opposite way instead of deleting it you make your apps think that your Java SE 8u45 is your Java SE 6. Well this article finally helped me http://stackoverflow.com/questions/19563766/eclipse-kepler-for-os-x-mavericks-request-java-se-6/19594116#19594116You will have to change the code and add your version of Java and dont forget to log out and back on!!!HOPE THIS HELPS!!!

Reply to Software Documentation - A Standard
For internal document which will explain the architechture, lifecyle, deployemnt procedures, isn't that the sort of thing that people spend endless hours arguing about in software development classes?I mean, there are standardized data flow diagram methods, software architecture diagram methods, and the like, probably as many different standards as you'd care to find.
