“missing package product”

It seems that the console log for XC7 misses a lot of data. If an app writes say 100 lines to NSLOG, only a subset will appear in console. Prior to 10.11 and XC7, this was never an issue.

Say I'd like to write a generic function dotProduct, something like:func dotProduct<T: FixedSizeArrayType where T.Element: BasicArithmeticType>(a: T, b: T) -> T.Element { var sum = T(0) for i in 0 ..< T.Count { sum = sum + a[i] * b[i] } return sum }This is just some haphazard pseudo code meant to illustrate the requirements for the function:It takes as arguments two fixed size arrays of equal length and element type and returns the dot product of the two arguments (the type of the return value is of course the same as the element type of the two arguments). It's also ok to make it as a method, with self replacing the first arg.I want compile time errors if I try to call it with arguments of different size/count/length or element type, and if I try to receive a return value of some other type than the element type of the two arguments.And as can be seen, The T.Element type should conform to an imaginary BasicArithmeticType protocol. This protocol is possible to write yourself, but currentl

I am using a LIst picker with multiple PickerItems with a title. Currently the picker is nested in a group with a background image. However, the picker seems to have a solid black background under the text?Am I doing wrong/missing something to make it transparent? Or is this by design?

Hello everyone,I have a query with regards to Game Center authentication capabilities. While taking this method into consideration I arrived at an edge case for which I would request some additional information or guidance. In the following event: 1.An user boots the app on an iOS device and authenticates with a Game Center account 2.Then resets the device to erase hishers information of it (maybe to sell it) 3.Picks up another device to play the same app on, but this time he does not sign in with a Game Center account 4.The user plays for a while and makes some progress 5.Then decides to sign back into the previously used Game Center account. At this point a conflict would arise between the existing progress information between the Game Center account and the local progress (achieved without the Game Center account). Given the available documentation, would it pose a concern to show user a warning dialog informing that due to the Game Center sign-in, the user can now either overwrite his current progress wit

In 10.11, I can't build anything in xCode. It just hangs on the Signing product step. This is with the newest xCode 7 beta as well as version 6.3.2.Any ideas?

Hihas this been asked as usual? Is it ok to install Xcode 7 beta aside to Xcode 6 such that Xcode 6 is not touched and able to use for production, submission, etc?Thanks!

My context. I have a right bar button item with a selector inside the same view controller. I also have a weak, read-only, synthesized property (with a shortcut name _myProperty on this view controller. When the bar button item is clicked, and I enter the selector method, I see that the value of _myProperty is nil. As far as I can tell, everything is fine up through viewDidAppear with the value of this property.When I make the property strong, it's no longer nil. This is the opposite of what I'd expect. What am I missing in my interpretation of weak and strong attributes?

I just migrated an app to use Swift 2 in Xcode 7, and after cleaning up all the changes and fixing errors missed, I can't get past an error:Command failed due to signal: Illegal instruction: 4Has anyone else experienced this? I have cleaned the build, removed Derived Data folder, and ensured I'm on latest version of CocoaPods with latest versions of pods (SVProgressHUD, KSReachability, Lockbox, SMPageControl).Please help, thank you!-BJ
