How to remove all subviews of a view in Swift

Question

I m looking for a simple method to remove at once all subviews from a superview instead of removing them one by one     I m trying something like this  but is not working let theSubviews   Array   container view subviews for  view   NSView  in theSubviews       view removeFromSuperview container view      What I am missing   UPDATE  My app has a main container view  I have to add different other views as subviews to container view in order to provide a sort of navigation   So  when clicking the button to  open  a particular page  I need to remove allsubviews and add the new one   UPDATE 2 - A working solution  OS X   I guess Apple fixed it   Now it is more easy than ever  just call    for view in containerView subviews      view removeFromSuperview

EDIT   thanks Jeremiah   Rollo   By far the best way to do this in Swift for iOS is   view subviews forEach    0 removeFromSuperview         this gets things done view subviews map    0 removeFromSuperview         this returns modified array      These features are fun   let funTimes     Awesome   Crazy   WTF   extension String        func readIt             print self           funTimes forEach    0 readIt             END EDIT  Just do this   for view in self view subviews       view removeFromSuperview       Or if you are looking for a specific class  for view CustomViewClass  in self view subviews           if view isKindOfClass CustomViewClass                view doClassThing

Here s another approach that allows you call the operation on any collection of UIView instances  or UIView subclasses   This makes it easy to insert things like filter after  subviews so you can be more selective  or to call this on other collections of UIViews  extension Array where Element  UIView     func removeEachFromSuperview         forEach          0 removeFromSuperview                Example usage  myView subviews removeEachFromSuperview       or  for example   myView subivews filter    0 is UIImageView   removeEachFromSuperview    Alternatively you can accomplish the same thing with a UIView extension  though this can t be called on some arbitrary array of UIView instances   extension UIView       func removeSubviews predicate    UIView  - gt  Bool     nil           subviews filter              predicate        in true             forEach                0 removeFromSuperview                      Example usage  myView removeSubviews   myView removeSubviews    0 is UIImageView

For removing just subviews of a specific class - this was the only Swift code that worked for me in Xcode6 1 1  Assuming the only subviews you want to remove are of type UIButton     for subView in nameofmysuperview subviews       if subView isKindOfClass UIButton            subView removeFromSuperview

I don t know if you managed to resolve this but I have recently experienced a similar problem where the For loop left one view each time  I found this was because the self subviews was mutated  maybe  when the removeFromSuperview   was called   To fix this I did   let subViews  Array   self subviews copy   for  var subview  NSView   in subViews       subview removeFromSuperview       By doing  copy    I could perform the removal of each subview while mutating the self subviews array  This is because the copied array  subViews  contains all of the references to the objects and is not mutated   EDIT  In your case I think you would use   let theSubviews  Array   container view subviews copy   for  var view  NSView   in theSubviews       view removeFromSuperview

For iOS Swift  to get rid of all subviews I use   for v in view subviews     v removeFromSuperview       to get rid of all subviews of a particular class  like UILabel  I use   for v in view subviews     if v is UILabel        v removeFromSuperview

Your syntax is slightly off  Make sure you cast explicitly    let theSubviews   Array lt NSView gt    container view subviews as Array lt NSView gt   for view in theSubviews        view removeFromSuperview
