Problem with AirPlay
On my iPad Air, when using AirPlay to stream audio, the audio isn't in sync with video content I'm playing. There is a big delay of almost 50ms. I'm using a B&W Zeppelin to stream the audio.(I assume that this is the place where bugs should be reported)

So long good community support.
The old forums weren't perfect, but they were exceleently laid out.This new social way of doing things is just plain wrong for developers.You can't find questions needing answers unless you go drilling down into each category, sorry I mean space. Which ipso facto means that getting your questions answered is a lot less likely to happen now. This s u c k s big time.Why can we not attach images?Why does a post with a URL in it get stuck in waiting for moderator for days and days at a time?

HKMetadataKeyMenstrualCycleStart metadata crash for HKCategoryValueMenstrualFlow type
Trying to implement the new menstrual flow object type in HealthKit, but getting an error when creating the sample. I coded it myself first, but it also fails with the code from WWDC 2015 session 203 video (about 11:24) below: let dict = [HKMetadataKeyMenstrualCycleStart: true] let type = HKCategoryType.categoryTypeForIdentifier(HKCategoryTypeIdentifierMenstrualFlow)! let value = HKCategoryValueMenstrualFlow.Medium.rawValue let date = NSDate() let sample = HKCategorySample(type: type, value: value, startDate: date, endDate: date, metadata: dict)This builds, but running results in the following on line 5 above:+[_TtCSs29_NativeDictionaryStorageOwner000000011941B4B0 hk_acceptsMetadataValue:]: unrecognized selector sent to class 0x11941b4b0Without the metadata dictionary, it complains at runtime that the specified key must be set in metadata. Either I'm missing something obvious and will have a big facepalm, or it'll likely be fixed in a beta++, but if anyone has better luck, please share.

Reply to NSTableView dynamic cell row height?
I’m afraid there’s no magic bullet for this. PeterNeg is right that you have to use -tableView:heightOfRow:, but it’s quite complicated to set up, because you’ll need to maintain a cache or row heights (so that you don’t recalculate them every time your delegate is queried, which will slow things down), and you’ll have to do all the height calculations on your own using NSLayoutManager methods. You’ll also need to observe changes to the frame of the edited text field, and changes to the text, and tell your table to resize accordingly.Below is a full breakdown of how I achieve this in my app. Mine is done in NSOutlineView and in Objective-C, but the principle is the same, so you can adapt this for NSTableView and Swift.1. Keep a dictionary of row heights. This will store the row height NSNumber against a unique ID of some sort associated with your model object.2. Maintain an isRecalculatingRowHeights BOOL.3. Implement a -recalculateRowHeights method which:a. Removes all objects from the rowHeights dictionary.b

Reply to iOS 9 Beta battery life
Update to my installs:iPad mini: The battery life finally went down to about 30% after using it for a day and half (last time on charger was when I installed beta and it didn't get to 100%). I streamed some audio for about 45 minutes. Charged back up to 100% and after sitting around for three hours and about 10 minutes of usage, it's still at 100%Usage:13 minStandby: 13 min <-- This does not match actual time off charge.iPod Touch: I went ahead and installed the beta on my iPod Touch. Charged it to 100% and after a few hours it's still holding a full charge.Usage: 9 minutesStandby: 3 hrs 27 miniPhone 5s: I use it as my main phone and for development. I'm not a big developer so I don't have test v. production iPhones, it's more of a hobby with a small income. I downgraded my iPhone back to iOS 8.3. I can update/test my apps on the iPod touch and iPad mini. I'll look at installing on my iPhone after a few more betas.

Universal 2D Game Assets and Absolute Node Positioning
I have a question regarding universal game assets and absolute positioning of a SKNodes in Sprite Kit (iOS 8+).I will try to present my problem through an example as follows:Imagine a 2D top down game with a SKSpriteNode which represents a house. A house has multiple child SKSpriteNodes which represent chairs, desk, sofa, etc.I have 3 versions of house asset:1x - 200 x 200px (Non-retina iPads),2x - 400 x 400px (Retina iPhones and iPads),3x - 600 x 600px (iPhone 6 Plus).Important: Child nodes (chairs, desk, etc.) positions are defined in a .plist file. Something like this (JSON representation):children: [ { position = {20,20}; }, ... ]Since the position is defined in points and not in pixels, everything gets positioned like expected according to device screen scale. For 1x devices the position stays {20,20}, for 2x position is {40,40} and for 3x the position is {60,60}.Problem:The problem is that 200x200px and 400x400px assets are way to small for iPad devices to achieve similar look and feel on all devices.Qu
