Hi everyone. Apple give a tutorial for learning how to make some apps, but it doesn't seem to work with the latest version of Xcode, which is giving me errors even running a blank app! I'll explain: I'm pretty much brand new at programming (I wrote a bunch of stuff in NetLogo a few years ago, and a *tiny* bit in Matlab way before that, but yeah, very very new). I want to learn Objective-C for what an app that won't be crazy complex, but also won't be the simplest thing in the world. To help, I've been reading Kochan's book on Objective-C programming. Anyways, I went to Apple's tutorial (https://developer.apple.com/library...rted/RoadMapOSX/chapters/01_Introduction.html) and started to do it simultaneously with Kochan's book. Right off the bat, the tutorial tells you to create a new app and just hit run with it blank. Then it starts with simple sliders / text box / button connections. So, I had no problem doing the work on the sliders and whatnot, but hitting run (even before doing ANYTHING) returns a list of 11 errors. Everything is in Frameworks/Other Frameworks/AppKit.framework. For example, in Frameworks/Other Frameworks/AppKit.framework/Headers/NSCell.h there are two lines that both give the error "Expected a type". The lines are: Code: - (NSUserInterfaceLayoutDirection)userInterfaceLayoutDirection NS_AVAILABLE_MAC(10_6); - (void)setUserInterfaceLayoutDirection:(NSUserInterfaceLayoutDirection)layoutDirection NS_AVAILABLE_MAC(10_6); So, is it even worth it to try with Apple's tutorial? I'm not sure why things are failing to run even before I enter any code, but I'm not sure how I'm going to get past problems located in the AppKit with my level of experience. Thanks for any feedback!
