问题 I use following code to see if the device is in landscape mode or not: UIDevice.currentDevice().orientation.isLandscape.boolValue It works BUT if I put my device in landscape mode before the app is launched, and after viewDidLoad , I call this line of code, it always returns false .

问题 I know that to program in STDIN and STDOUT, we need to make an command line project in Xcode. But how do I take a standard input in playground. Whenever I try to run such code in playground var input = readLine()! I always get this error Execution was interrupted, reason: EXC_BAD_INSTRUCTION (Code=EXC_l386_INVOP, subcode=0x0) Is it possible to take STDIN in playground or not? UPDATE I know this error is because of nil input variable but want to know how to overcome this nil value. 回答1: Fixed
