Recently I moved to Xcode 7 and Swift 2.0 since my app wouldn't compile on iOS 9 (any device), however on iOS 8.xx it ran as expected.
I have looked around Xcode and tried to find some reasons, but all I could find was that when it gets stuck on the launch screen, pressing pause in the Xcode debugger tells me that the code is on objc_msgSend
. The CPU usage also hits 100% (use to only be ~10-20% on 8.xx).
Nothing else out of the ordinary. Everything worked fine on Xcode 6.4. I migrated all the code to swift 2.0 - I do not have any compiling errors - except ld: warning: directory not found for option '-F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.0.sdk/Developer/Library/Frameworks'
but from what I've googled this isn't the biggest of my problems. I have no idea what to do anymore.
If you require parts of my code or whatever just let me know and I'll post it :)
Thanks!
Edit : Changed the storyboard to start at a regular ViewController
and a label and it runs fine. Seems like it has something to do with me using a UISplitViewController
. Here's some code from AppDelegate.swift:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//get split VC
let splitViewController = self.window!.rootViewController as! UISplitViewController
splitViewController.delegate = self
//Configure the master part
let masterNavigationController = splitViewController.viewControllers[0] as! UINavigationController
masterNavigationController.navigationBar.tintColor = UIColor(red: 236/255, green: 240/255, blue: 241/255, alpha: 1)
masterNavigationController.navigationBar.barTintColor = UIColor(red: 40/255, green: 162/255, blue: 47/255, alpha: 1)
let controller = masterNavigationController.topViewController as! NoteListViewController
controller.context = self.managedObjectContext!
//configure the detail
let detailNavController = splitViewController.viewControllers.last as! UINavigationController
let detailViewController = detailNavController.topViewController as! NoteDetailViewController
detailViewController.navigationItem.leftItemsSupplementBackButton = true
detailViewController.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem()
detailNavController.navigationBar.barTintColor = UIColor(red: 40/255, green: 162/255, blue: 47/255, alpha: 1)
//configure the data for detail
controller.delegate = detailViewController
let firstNote = fetchFirstResult(inContext: controller.context)
if firstNote != nil{
detailViewController.note = firstNote
detailViewController.context = self.managedObjectContext!
controller.tableIsEmpty = false
controller.appHasLoadedOnce = false
}
return true
}
Check you Storyboard. Seems your screen contains TextField(s) with default text in it. Simply clear text in this TextField and try again.
