“show when run”

Hello everyoneI'm developing an ios app using xCode Version 9.0.I'm trying to run my app on my iPhone version 11.0.1 but an error message shows up that says:- Code signing error - signing for xxx requires a development team. Select a development team in the project editor. - Code signing is required for product type 'application' in SDK 'iOS 11.0'.So, what does that mean?I tried to add a team by adding my Apple ID but it didn't work, when I try to sign in with my ID an error message shows up that says:This action could not be completed, try again.I tried again many times for few days but nothing changed, what should I do?

Hi everyone,I'm stuck in one of my applications and need your help.So, the app is having a functionality where the user will start timer from the app and unless & until he/she didn't stop, it must be running even if the app is in background or not running in background too.So, lets say the user starts the timer and after 3minutes the app is terminated, then when user starts the app next time the timer must continue from 3minute onwards.I'm thinking to use the GCD Timer. So, please help me with this situation.Thanks in advance

I created 4 targets to support watchOS 1 & 2, but failed to show the correct Glance screen, only a black screen. If I delete targets of watchOS 1, everything will be ok.Questions:1. How to maintain targets of watchOS 1 & 2 simultaneously and Glance screen still can work?2. How to execute the app of watchOS 1 when targets of watchOS 1 & 2 exist simultaneously?All tests were done in the simulator. Here is my test project: https://dl.dropboxusercontent.com/u/31258390/test.zip (Xcode 7 GM, iOS 9 SDK)Anyone has solutions? Thanks!

I have a PageContainerViewController ( a regular view controller with nothing in it ) that I Show Detail present from a previous view controller, which is supposed to embed a UIPageViewController in itself. The UIPageViewController is supposed to show, right now, two View Controllers, but it doesn't. The PageContainerViewController shows up as a blank white screen, and the UIPageViewController seems to be nowhere (I changed the background color to a bright green and still all I see is white).Here's my code in PageContainerViewController (which has the UIPageViewControllerDataSource): var pageViewController: UIPageViewController? lazy var orderedViewControllers: [UIViewController] = { return [self.newVc(viewController: vc1), self.newVc(viewController: vc2)] }() var currentlyShowingIndex = 0 func newVc(viewController: String) -> UIViewController { return storyboard!.instantiateViewController(withIdentifier: viewController) } override func viewDidLoad() { super.viewDidLoad() pageVie
