A Summary of the WWDC25 Group Lab

Hello there smart programmers,Here is a summary of what we have so far:- our own Apple developer Enterprise membership- mac OSX Server (4.1.3) running on a mac mini- our own DEP account activated at (deploy.apple.com), our server and one ios device linked to it- The latest documentation of the MDM Protocols (2015-07-13)So far, via the apple developer API's, we can consume the DEP Web Services (List Account details, Fetch Devices etc...).What we need is to be able to create configuration profiles, and push those profiles into our own devices, can any of you guide us trough the steps to do so?Kind Regards,Actacom Nederland B.V.

In a compute (kernel) function, is there an implicit ordering to threadgroup execution.Say I have a 32xN buffer. Take following trivial kernel (ignoring boundary conditions):kernel void example(device uint *buffer [[ buffer(0) ]], const uint2 pos [[ thread_position_in_grid ]]) { uint index = pos.y * N + pos.x; buffer[i - 1] = buffer[i] buffer[i + 1] = 0; }If we dispatch that kernel in N 32x1 threadgroups, is there any way that the thread groups are executed left-to-right? i.e. the resulting buffer is all 0 (once again, ignoring the boundary conditions).Thanks

This is my code for the background chessboard. I need three different images, which is fine. if deviceType == iPad { backImagePad.anchorPoint = CGPointMake(0.5, 0.5) backImagePad.size.height = self.size.height backImagePad.size.width = self.size.width backImagePad.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)) self.addChild(backImagePad) } if (deviceType == iPhone5 || deviceType == iPhone6) { backImagePhone5.anchorPoint = CGPointMake(0.5, 0.5) backImagePhone5.size.height = self.size.height backImagePhone5.size.width = self.size.width backImagePhone5.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)) self.addChild(backImagePhone5) } if (deviceType == iPhone) { backImagePhone.anchorPoint = CGPointMake(0.5, 0.5) backImagePhone.size.height = self.size.height backImagePhone.size.width = self.size.width backImagePhone.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)) self.addChild(backImagePhone) }However, to individually position th

Our app has a watchkit app + extension. Archives from XCode IDE always pass iTunes store validation. However archives generated via xcodebuild command tools (Xcode 6.4; Build version 6E35b) fail this validation with the following errors:ERROR ITMS-90163: Invalid Code Signing Entitlements.

I recently added support for Time Travel in my complications and everything is working as expected, but the complications are always animating instead of just when the group identifier changes.For example I'm using a ring template with some text and I don't want to have the complication animate when just the text changes. Therefore I'm using the same identifier for all timeline entries when only the text changes.But this isn't working correctly.Is this a known problem with watchOS 2 beta 5? Or is it just the Simulator? I couldn't test it on an actual device yet.I'm specifying CLKComplicationTimelineAnimationBehaviorGrouped as the animation behavior for all complications:- (void)getTimelineAnimationBehaviorForComplication:(CLKComplication *)complication withHandler:(void(^)(CLKComplicationTimelineAnimationBehavior behavior))handler { handler(CLKComplicationTimelineAnimationBehaviorGrouped); }And this is how I create the timeline entries for Time Travel using the same identifier, of course:CLKComplicat

I have some preferences that are currently stored in the main app's Settings bundle. These are global settings that should affect my iOS app, Today extension, and watchOS 2 app. I am able to share settings with the widget by using app groups and shared NSUserDefaults, but how can I now share those settings with the watchOS 2 app? If it's not possible to share these same settings with the watch, I would accept duplicating them and adding them to the Watch app (they may want to have different settings for the watch anyways). But if I do that I'm not sure how to access them from within a watchOS 2 app. What do you suggest?

I've been testing El Capitan Beta 6 on a MacBook Air and I found one issue that I hope someone can confirm is a bug, or maybe I'm just doing something wrong.Starting with a USB bootable El Capitan Beta installer, initialize the SSD target drive, then install El Capitan, then go through the tedious/painful process of having 10+ GBs of updates pulled down (just a guess), until we are at El Capitan Beta 6.Right off the bat I notice Recoverey HD is missing.Running diskutil list shows Macintosh HD is there, but not Recovery HD.Running diskutil cs list returns No CoreStorage logical volume groups found.I booted off the USB bootable El Capitan Beta installer and created a DMG using both New image from Macintosh HD and New image from folder... this way I can at least restore Macintosh HD at a later date if necessary (fully updated to Beta 6).I didn't bother to create an image from the SSD, since it is missing Recovery HD. Ideally I should be able to, to capture both Macintosh HD and Recovery HD.I'll probably
