Presenting modal in iOS 13 fullscreen

Question

In iOS 13 there is a new behaviour for modal view controller when being presented   Now it s not fullscreen by default and when I try to slide down  the app just dismiss the View Controller automatically   How can I prevent this behaviour and get back to the old fullscreen modal vc     Thanks

As a hint  If you call present to a ViewController which is embedded inside a NavigationController you have to set the NavigationController to  fullScreen and not the VC  You can do this like  davidbates or you do it programmatically  like  pascalbros   The same applies to the UITabViewController An example scenario for NavigationController         BaseNavigationController  UINavigationController        let baseNavigationController   storyboard  instantiateViewController withIdentifier   quot BaseNavigationController quot       var navigationController   UINavigationController rootViewController  baseNavigationController      navigationController modalPresentationStyle    fullScreen     navigationController topViewController as  LoginViewController     self present navigationViewController  animated  true  completion  nil

One Liner   modalPresentationStyle is required to be set on the navigationController which is being presented        iOS 13 and below iOS version fullScreen with overCurrentContext and   navigationController   Tested Code  let controller   UIViewController   let navigationController   UINavigationController rootViewController  controller  navigationController modalPresentationStyle    overCurrentContext self navigationController  present navigationController  animated  true  completion  nil    modalPresentationStyle require to set at navigationController

class MyViewController  UIViewController        convenience init             self init nibName nil  bundle nil          self modalPresentationStyle    fullScreen            override func viewDidLoad             super viewDidLoad             Rather than call self modalPresentationStyle    fullScreen for every view controller  you can subclass UIViewController and just use MyViewController everywhere

There are multiple ways to do that  and I think each one could fit for one project but not another  so I thought I ll keep them here maybe someone else will run to a different case     1- Override present  If you have a BaseViewController you can override the present   viewControllerToPresent  animated flag  completion   method   class BaseViewController  UIViewController                 override func present   viewControllerToPresent  UIViewController                          animated flag  Bool                          completion      - gt  Void     nil        viewControllerToPresent modalPresentationStyle    fullScreen     super present viewControllerToPresent  animated  flag  completion  completion                     Using this way you don t need to do any change on any present call  as we just overrode the present method   2- An extension   extension UIViewController     func presentInFullScreen   viewController  UIViewController                             animated  Bool                             completion      - gt  Void     nil        viewController modalPresentationStyle    fullScreen     present viewController  animated  animated  completion  completion          Usage   presentInFullScreen viewController  animated  true     3- For one UIViewController  let viewController   UIViewController   viewController modalPresentationStyle    fullScreen present viewController  animated  true  completion  nil    4- From Storyboard  Select a segue and set the presentation to FullScreen    5- Swizzling  extension UIViewController      static func swizzlePresent          let orginalSelector    selector present    animated  completion        let swizzledSelector    selector swizzledPresent       guard let orginalMethod   class getInstanceMethod self  orginalSelector   let swizzledMethod   class getInstanceMethod self  swizzledSelector  else return       let didAddMethod   class addMethod self                                         orginalSelector                                         method getImplementation swizzledMethod                                          method getTypeEncoding swizzledMethod        if didAddMethod         class replaceMethod self                            swizzledSelector                            method getImplementation orginalMethod                             method getTypeEncoding orginalMethod         else         method exchangeImplementations orginalMethod  swizzledMethod                 objc   private func swizzledPresent   viewControllerToPresent  UIViewController                                 animated flag  Bool                                 completion      - gt  Void     nil        if  available iOS 13 0             if viewControllerToPresent modalPresentationStyle     automatic           viewControllerToPresent modalPresentationStyle    fullScreen                   swizzledPresent viewControllerToPresent  animated  flag  completion  completion           Usage  In your AppDelegate inside application   application  didFinishLaunchingWithOptions  add this line     UIViewController swizzlePresent     Using this way you don t need to do any change on any present call  as we are replacing the present method implementation in runtime  If you need to know what is swizzling you can check this link  https   nshipster com swift-objc-runtime

If you are using a UINavigationController and embed a ViewController as a root view controller  then also you would rise up with same issue  Use following code to overcome   let vc   UIViewController   let navController   UINavigationController rootViewController  vc  navController modalPresentationStyle    fullScreen

I had this issue on the initial view right after the launch screen  The fix for me since I didn t have a segue or logic defined was to switch the presentation from automatic to fullscreen as shown here

I achieved it by using method swizzling Swift 4 2    To create an  UIViewController extension  as follows  extension UIViewController         objc private func swizzled presentstyle   viewControllerToPresent  UIViewController  animated  Bool  completion      - gt  Void               if  available iOS 13 0                   if viewControllerToPresent modalPresentationStyle     automatic    viewControllerToPresent modalPresentationStyle     pageSheet                   viewControllerToPresent modalPresentationStyle    fullScreen                                  self swizzled presentstyle viewControllerToPresent  animated  animated  completion  completion              static func setPresentationStyle fullScreen              let instance  UIViewController   UIViewController           let aClass  AnyClass    object getClass instance           let originalSelector    selector UIViewController present   animated completion            let swizzledSelector    selector UIViewController swizzled presentstyle   animated completion             let originalMethod   class getInstanceMethod aClass  originalSelector          let swizzledMethod   class getInstanceMethod aClass  swizzledSelector          if let originalMethod   originalMethod  let swizzledMethod   swizzledMethod           method exchangeImplementations originalMethod  swizzledMethod                      and in AppDelegate  in application didFinishLaunchingWithOptions  invoke the swizzling code by calling   UIViewController setPresentationStyle fullScreen

All the other answers are sufficient but for a large project like ours and where navigations are being made both in code and storyboard  it is quite a daunting task      For those who are actively using Storyboard  This is my advice  use Regex    The following format is not good for full screen pages    lt segue destination  Bof-iQ-svK  kind  presentation  identifier  importSystem  modalPresentationStyle  fullScreen  id  bfy-FP-mlc   gt    The following format is good for full screen pages    lt segue destination  7DQ-Kj-yFD  kind  presentation  identifier  defaultLandingToSystemInfo  modalPresentationStyle  fullScreen  id  Mjn-t2-yxe   gt    The following regex compatible with VS CODE will convert all Old Style pages to new style pages  You may need to escape special chars if you re using other regex engines text editors   Search Regex   lt segue destination        s  kind  show  identifier        id         gt    Replace Regex   lt segue destination   1  kind  presentation  identifier   2  modalPresentationStyle  fullScreen  id   3   gt

an alternative approach is to have your own base viewcontroller component in your app  and just implementing the designated and required initialisers with a basic setup  something like the  following   class MyBaseViewController  UIViewController      MARK  Initialisers      Alternative initializer which allows you to set the modal presentation syle     - Parameter modalStyle  the presentation style to be used init with modalStyle UIModalPresentationStyle        super init nibName  nil  bundle  nil      self setup modalStyle  modalStyle     override init nibName nibNameOrNil  String   bundle nibBundleOrNil  Bundle         super init nibName  nibNameOrNil  bundle  nibBundleOrNil         default modal presentation style as fullscreen     self setup modalStyle   fullScreen     required init  coder  NSCoder        super init coder  coder         default modal presentation style as fullscreen     self setup modalStyle   fullScreen       MARK  Private      Setup the view         - Parameter modalStyle  indicates which modal presentation style to be used     - Parameter modalPresentation  default true  it prevent modally presented view to be dismissible with the default swipe gesture private func setup modalStyle UIModalPresentationStyle  modalPresentation Bool   true       if  available iOS 13               self modalPresentationStyle   modalStyle         self isModalInPresentation   modalPresentation           NOTE  If your view controller is contained in a navigation controller which is actually presented modally  then the navigation controller should approach the problem in the same way  meaning  having your custom navigation controller component customised in the same way  Tested on Xcode 11 1 on iOS 13 1 and iOS 12 4  Hope it helps

With iOS 13  as stated in the Platforms State of the Union during the WWDC 2019  Apple introduced a new default card presentation  In order to force the fullscreen you have to specify it explicitly with   let vc   UIViewController   vc modalPresentationStyle    fullScreen   or  overFullScreen for transparency self present vc  animated  true  completion  nil

User · Answer

Initially  the default value is fullscreen for modalPresentationStyle  but in iOS 13 its changes to the UIModalPresentationStyle automatic   If you want to make the full-screen view controller you have to change the modalPresentationStyle to fullScreen   Refer UIModalPresentationStyle apple documentation for more details and refer apple human interface guidelines for where should use which modality
