DTiPhoneSimulatorErrorDomain Code 2

I recently renewed my iOS Certificate and now one of my apps that has been on the app store and using game center will no longer let me sign in. When Game Center is trying to authenticateLocalPlayer I get GKErrorDomain Code=15 The requested operation could not be completed because this applicaion is not recognized by Game Center. Also when I go to iTunes Connect I see on my app page in red Leaderboard is not a member of a leaderboard set attached to version 2.0. I don't know what I am missing to get Game Center working again for my device. Any help would be appreciated, thank you!

Copying out of iBooks is terrible. You can copy one line of code but with more than one line you get extra characters and a stupid line about the book. I am trying to learn Swift and typing in long sequence, or having to manual edit the copied text first is irritating.

Is it me? When you have two apps in split view, how do you change either side to another app easily? I'm not sure if its being buggy or if its actually this hard to change to another app?

HiI have an iPad 2 (Model 1395). I followed the instructions and downloaded iOS 9 Beta for my device. The file name is iOS_9_beta__iPad_2_WiFi__13A4254v.zip. When I try and install it, I get a message telling me that the update is incompatible with the firmware. Has anyone else run into this issue? Thanks,sb

There's a weird behaviour in Xcode when writing Swift code.Try to write this code for example:var fullName: Bool { get { return firstName + + lastName } set { splitFullName(fullName); } }Now what really happens is this:var fullName: Bool { get { return firstName + + lastName } set { splitFullName(fullName); } }That weird indentation is something that Xcode strongly insists on. And I know that although Apple developer seem to think that brackets on the same line is better for some reason, there's no way in **** they think that that indentation is correct!

Hey guys,as 'appearanceWhenContainedIn' is deprecated in iOS 9 and should be replaced with 'appearanceWhenContainedInInstancesOfClasses' I want to tweak my code to that effect. But how to do that? I didn't find something in the official documentation. ATM, my code looks like this:[[UIScrollView appearanceWhenContainedIn:[UITableView class], nil] setBackgroundColor:[UIColor whiteColor]];How do I rewrite this snippet for iOS 9 using 'appearanceWhenContainedInInstancesOfClasses'? Thanks in advance! 🙂Alex

So I downloaded the latest Lister sample code for Xcode 7.0b1. I set up the bundle identifier prefix, the development team, and the provisioning profiles as specified in the PDF that came with the sample code. I then tried to build it, but got the following error:---Failed to code sign ListerKit (watchOS).No valid signing identities (i.e. certificate and private key pair) matching the team ID “A93A5CM278” were found.Xcode can attempt to fix this issue.---I don't recognize that team ID, so I'm guessing it's one of Apple's internal accounts. I'd like to change it, except that the General tab, where the setting is normally changed, is not present when I choose the ListerKit (watchOS) framework in the project's target list. It is present on the OS X and iOS framework targets.Is anyone outside of Apple able to build this sample code? If so, then what did you do to get the watchOS framework to build?

Hello,When I attempt to open the Guided Tour playground file mentioned in the pre-release Swift programming book in Xcode 7 on El Capitan (first build), Xcode crashes immediately upon opening. I've been able to use it fine with other projects/playgrounds etc, its just this indiviudal one.I've included a snippet of the crash log - does anyone know of a fix for this?Thanks in advance.Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Application Specific Information: ProductBuildVersion: 7A120f ASSERTION FAILURE in /Library/Caches/com.apple.xbs/Sources/IDELanguageSupport/IDELanguageSupport-8102.19/IDELanguageSupportUI/Playground/Editor/IDEPlaygroundSourceTextScrollView.m:322 Details: result should be an instance inheriting from IDEPlaygroundTextView, but it is nil Object: <IDEPlaygroundSourceTextScrollView: 0x7f8ffd8cebc0> Method: -_drawGutterAndResultSidebarBackgroun
