show when run

So I'm tryin to install an blank application on my device but It doesn't show on the Run on Target in Xcode, but when I look at manage run destination it shows my device?

Environment: OS X macOS Sierra 10.12.2, Xcode 8.2.1, iPhone 7 running 10.2, app written in Swift.I'm having a chronic problem where log messages from my app only show in the Xcode log window the first time I run the app after booting the phone. If I rebuild and run the app again, the messages don't appear. The issue persists whether I use NSLog or Swift's print statement to print the messages. If I use NSLog they show up in the Console app, and that's an OK workaround - except one of the third-party libraries I use apparently uses print or equivalent to write messages to stdout/stderr.Has anyone else seen this issue? It's pretty chronic across my team here; I'm surprised I haven't seen other messages about it...-David

Description: I am new to IOS development. I followed the tutorial on Apple's official website to learn, and the URL is below: [https://developer.apple.com/tutorials/app-dev-training/creating-a-storyboard-app) However, when I run the app, the app's screen is always blank. I'm pretty sure I followed by the official tutorial step by step. What I have tried: Check the mark of is Initial view controller at Main.storyboard Cancel the mark of is Initial view controller at Launch.storyboard(if I didn't cancle the mark, the label Im a label of Launch.storyboard will show up for one second and then come up a blank screen.) Delete the view controller and add a new one. I check the Info, it seems fine: My Environment: Xcode: 13.1 Simulator: ios15 Simulator: iphone 12 pro Looking forward for response, and thank you~

Evening, I'm relative newbie about Xcode.I'm solving an exercise and in the Toolbar i can see that the running process is keeping running for ever.Some times after several minuts it give me output and errors, some times it just keep running.I was thinkg it was a problem of my code, but even starting a new playground the running process is ver very slow, like 1 minute to solve the example string variable.I've tried to reboot xcode, reboot os, unistall and install again xcode but I still have the same problem.Xcode Version 7.3.1 (7D1014)Any tips?

Hello:I have the following code. I am developing an app for Mac OS. I have a UI with text fields for user input which is saved after each item is entered. When I run the code I get no errors but also I get no response from the print statements. I did not cast any fields as delegates. If that is necessary, How can I did that?I would appreciate any help with the code that may identify the problem.import AppKitimport Cocoaimport Foundationimport CoreDataclass RegistrationViewController: NSViewController, NSApplicationDelegate {var students: [NSManagedObject] = [] @IBOutlet weak var firstNameTextField: NSTextField! override func viewDidLoad() { super.viewDidLoad() firstNameTextField.stringValue = UserDefaults().string(forKey: fnTextFieldKey) ?? } override func viewDidAppear() { print(Documents Directory: , FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).last ?? Not Found!) } @IBAction func saveFirstName(_ sender: Any) { print (starting code for save name field) guard (NSApplicatio

Hi, I want user to be able to see the route he takes during walk or run on a map, while he is walking and after in history. I have got the users location and loaded a map. From what i have read, i'lll have to continuously annotate the map with a marker while the user is walking or running. But I don't clearly understand the MapKit apis for annotation and annotation view. Can someone guide me how to go about it. I just need an overview. Thanks

I want to show an NSAlert sheet modal when my single-window app first launches, but doing so makes the window jump when it first opens.The window is restoring the user's last chosen size & position (I have set the Autosave name in IB). This works, but appears to be done AFTER my code that shows the modal sheet.I'm only really talking about the following 3 lines of code:override func viewDidAppear() { let alert = NSAlert.init() alert.beginSheetModal(for: self.view.window!) { (returnCode: NSModalResponse) -> Void in } }I'm guessing viewDidAppear() doesn't mean the window has finished positioning and sizing itself from the user defaults, but for the life of me cannot find a method that gives this to me.Since a picture is worth a thousand words, I've put up a demo at https://github.com/jeff-h/WindowPositioning

my iTunes Connect is showing the results for the last week rather than 'yesterday' when running on iOS10 beta. anyone seeing this?

My game has several SavedGames and they are retrieved succesfully using FetchSavedGames except when I run the game for first time after install, no exceptions, no errors, just shows 0 saved games.Once I'm inside the game I call the method again and shows the correct results.This call is one of the first actions the game algorythm makes, just in case has something to do.Any idea why this might happen?Thanks,pistoleta.EDIT: More people with same problem, no sollutions:https://stackoverflow.com/questions/40992442/gklocalplayer-fetchsavedgameswithcompletionhandler-returns-0-games-on-installati/60728584#60728584

When running on my iPhone SE3 under IOS 18.4.1, achievement banners show as expected. The same code running on my iPad Air2 under IOS 15.8.4, achievement banners do not show, but they are accepted (as shown in the GameCenterViewController). The banners also don't show when running the simulator under iPhone 16 Pro Max under IOS 18.2 or simulator under iPhone SE3 under IOS 18.3. I haven't tried others. [Note that I clear the achievements each run during test so that I can duplicate this]
