 Problem: System data has huge data.How can i delete the data and recover my spaces in my mac?. I had tried to delete xcode caches and other things but i'm not able to resolve. Solution: clear the the data inside the path that not used with device id you can find from xcode->menu->window->devices and simulator-.>simulator then it will show the identifier. You can check with the below device list and find the unused old one. you can remove the old and unused simulator data in the path to delete /Users/yourMac/Library/ Developer/CoreSimulator/ Devices. Because the xcode keeps the old simulators on the above path but it's not used in the new xcode. So it has huge data with unused.You can remove all and proceed. Then the system data will be low after doing this work.

Then follow the code.      override   open   func   viewDidLayoutSubviews () {          super . viewDidLayoutSubviews ()                  if   let  statusView =  self . view . viewWithTag (9999) {            statusView. isHidden  =  UIDevice . current . orientation . i sLandscape         }     }      override   var   prefersStatusBarHidden :  Bool  {          return   UIDevice . current . orientation . i sLandscape     } You can hide the view while from landscape then if it rotated to portrait it will automatically shown.

 Problem: I had enabled portrait and landscape in info.plist but i want to enable one screen in landscape allowed and other screens only on portrait.How to achieve that? Solution: First you must enable the both portrait and landscape in info.plist.Then add the below code in appdelegate      func   application ( _  application:  UIApplication ,  supportedInterfaceOrientations For  window:  UIWindow ?) ->  UIInterfaceOrientationMask  {          if   let  vc =  UIApplication . topViewControlle r ()  as ? my viewController  {              // Only allow portrait (standard behaviour)              print ( "landscape called" )              return  . all ;         }          print ( "portrait called" )          return  . portrait ;     } Then it will be working fine.Happy coding..

Below are coredata initilisations in my appdelegate. //     MARK: -     Get the context func   getContext   () ->   NSManagedObjectContext   {       var   context:   NSManagedObjectContext ?       if   #available (iOS 10.0, *) {           context =   persistentContainer . vie wContext       }   else   {           context =   managedObjectContext       }            return   context! }       lazy   var   persistentContainer :   NSPersistentContainer   = {           let   container =   NSPersistentContainer ( name :   APP_INFO . containerName )           let   dir =   FileManager . default . containerU RL
