missing package product

I have a view controller, I want to action something on the view by calling a method in the view. But I get the errorfatal error: unexpectedly found nil while unwrapping an Optional valuebecause the view object isnt set. There are a couple of issues here, firstly I assume I am with MVC allowed to control the view from the view controller? Secondarily am I missing some association between the two, maybe on the storyboard? or do I set it up another way...Sorry for the basic question, but sometimes I get a bit lostKind regardsMark

Just learning Swift and I noticed that Apple's example code on the Swift homepage does not compile in playground! I mean really, am I missing something?https://developer.apple.com/swift/extension String { var banana : String { let shortName = String(dropFirst(characters)) return (self) (self) Bo B(shortName) Banana Fana Fo F(shortName) } } let bananaName = Jimmy.bananaI changed line 03 to: { let shortName = String(dropFirst(self))This seems to work. I tried to find feedback and let them know, but there seems to be no place for developers to provide simple feedback.

I have just installed iOS 9 on my iPhone 6 Plus and when it started up it wiped my apple watch and I had to set it up again.After setting my apple watch up again I am missing the Activity Data for the last 48 hours, but when i look at the activity app on my phone the steps and what not are there but the rings for the last 2 days are both empty

I'm having a problem running my Xcode project on my Apple Watch. It says my iPhone + Apple Watch are ineligible because the OS on the watch doesn't support WatchKit App Products. My iPhone is running iOS 9 and my Watch is running watchOS 2. I've tried rebooting both devices and plugging/replugging in the iPhone.

When trying to install a package I received the error A Python runtime could not be located. Has Python moved on 10.11 or is there a special framework I need to install?Thanks in advance.

Have tried 5 or 6 times now it install the beta package for 1474 on two diffrent computers. Each time the install freezes after about 10% and itunes pops and error code 14. I have tried diffrent cables and ports with no luck so far. I have tried redownloading the package to insure it wasnt corrupted but still no luck. It restores to 8.3 from both computers without trouble. I am unsure what to do from here. Has anyone else come across this and resolved it? Any suggestions as to what to try next? Your help is appreciated.

Since installing El Capitan, my hard disk keeps filling up to the point my system says it will lose messages and emails. I also noticed I could not log out of iCloud. Lastly Activity Monitor is missing.I have done all the normal things ... empty trash, delete downloads, purge unused apps, restarted, set up a new admin user and logged in from there. While doing these things did create more space ... within minutes it is gone again.Any thoughts would be appreciated ....

I created a simple model in an obj and attempted to load it as an Assetlet bundle = NSBundle.mainBundle() let path = bundle.pathForResource(Torus, ofType: obj) var torusModel = MDLAsset(URL: NSURL(string: path!)!)Error message: Could not load data from /Users/jason/Library/Developer/Xcode/DerivedData/MetalDemo-auxpwrdxoklbrpbtkxmrhkecewhb/Build/Products/Debug/Met ... orus.obj

HiI'm validating my receipts against the appstore, following the Apple's guide The receipt is retrieved from the bundle using the following code:NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];NSString *base64Receipt = [receipt base64EncodedStringWithOptions:0];The encoded receipt is a signed binary file, as described in the documentation. However, in some weird cases the receipt is not the expected binary file but an NSDictionary with the form{ pod = 50; purchase-info = ewo...; signature = Apdx...; signing-status = 0;}When I try to validate those receipts against the appstore, the result is always 21002 (The data in the receipt-data property was malformed or missing). Any ideas in why the receipt retrieved from the bundle is in the wrong format?Regards
