After updating to Xcode 6.1 , I'm getting Error Like : 'UIImage?' does not have a member named 'size' var image = UIImage(named: imageName) let sizeOfImage = image.size Is it bug with my code or Apple ?

问题 I have an issue that I can not seem to find the solution for. I am new to Swift and was trying to create a TicTacToe game.

问题 I followed the Apple documentation to move a textfield upwards when the keypad appears.

And I want it to popup when I press the button. For some reason I get the following error whenever I press the button: ... this class is not key value coding-compliant for the key view.' I have read that this is because of outlets from the NIB which have been deleted or changed, that's why I removed all objects and what to
