“Popping Sound”

I'm an OS X developer, but I think I can help you since Auto Layout works basically the same way on both platforms. It's perfectly fine to modify constraints anywhere (except in layout() or any similar methods that actually do the layout work). For example, I like to modify constraints in my action methods (you know, like swapping out detail views when the setting of a pop-up button is changed) or in my animation context completion handlers. Or, if you really want to use updateConstraints, just call self.needsUpdateConstraints = true and updateConstraints will be called at the end of the run loop cycle. (This is great for performance because you can set the needsUpdateConstraints as many times as you wish and the actual work will only happen once.)

You got me slightly wrong over here. Let my store be local and not in a ubiquity container. Every new entry in the store will have a unique identifier. When a new entry is added to the store, the managed objects are synced between devices as records in the cloudkit key value dictionary. Then on another peer, they are inserted into the context and saved all over again in the store local to that devices. When an entry is deleted from a devices the unique identifier is synced over to the other peers and marked for deletion and then the code on the other peer finds the primary entity matching the identifier and follows the delete logic on the other peer (deleting the primary entiriy, setting its relationship end entity pointer to nil and if this was the last primairy entity object in the relaitonship end object's NSSet, delete it as well) In case of editing the primary entity i simply delete the old entry and add a new one to avoid writing a separate logic for changed relationships. Basically my problem in core d

Nils while unwrapping optionals at launch sound like a missing IBOutlet connection in a XIB file. Drop a few breakpoints across your app delegate and view controller lifecycle methods - might catch it that way.

Unfortunately not, that was actually where I found the information to test the basic script. I honestly didnt know the libraries even existed until I ran into a problem with this script and did some deep diving haha.The accept entry looks like this:accept v : Accepts an incoming text, audio, or video chat invitation, or file transferaccept chat or file transfer

Could you file a bug report with your test case so we can take a look. Please include information that indicates which version(s) of iOS / OSX you're using to reproduce this error. We didn't see that information in your post and Core Audio engineering have fixed some issues in this area recently.Regarding the example code snippet itself, the file is not actually scheduled on the player, so this will result in the playback of silence. However, this is independent of your original error/exception.

You will need a third button - operate in the 'lite' mode. All apps must do something. They can have a 'lite' mode and, after IAP, they can have an upgraded mode - in your case 'licensed mode'.It sounds like you will want to use a non-renewing subscription. You will need some way for users to copy their subscription from one device to another - you can do that through your servers or through the user's iCloud account. Alternatively you could sell a license forever using a non-consumable IAP - in which case you will need a restore function.Since this is a question about IAP's you might get additional answers if you posted it on the IAP forum.

Ok, sounds good...I am going to try and log out and try to log back in. I do see under downloads that there is like a 6GB file that said 10.11 and has a July 1st date...I don't know if that is all 3 beta or what? lol

Ugh, was really hoping AirPlay (audio) would be fixed. It's not.

Sounds like some unexpected behavior going on there. Might seem like the worst thing in the world, but can be easily fixed. Given the issue you are having there, I would suggest transferring any purchases that are on the device alone back to iTunes and then restoring the iPhone back to factory (but with iOS 9b3 installed).EDIT:Also when setting the iPhone back up, avoid restoring any backups and ensure that you're using manual syncing! This is important; otherwise iTunes and iOS will sync based on one library and when testing betas, you don't want to hit a random bug.

It's not a suggestion. You are definitely allowed to run your own apps on your own devices now without a paid membership. I'm not an iOS developer, so I don't know precise details, but I think if you're signed in with the same AppleID on both Mac and iOS and connect the iOS device to your Mac, you should be able to select your iOS device as a run destination from the Scheme pop-up just to the right of the run/stop buttons in the toolbar.
