the project doesn’t compile, something about AutoLayout+Extensions.swift:47:127: 'Attribute' is not a member type of 'NSLayoutConstraint'
None of them are working…downloaded all the projects and final didn’t work for any one of them
Are you running the projects on Xcode 10?
@leamars im so sorry! please forgive me. Can you please tell me why things change so much, why code is so different?
No worries. I’m not sure what to tell you about why things change so much, haha. It’s the Swift 4.2 update really. The language is still very young and actively evolving (which is a great thing!) so we just have to embrace the constant new developments and iterations 
No my version is Version 9.4.1 (9F2000). Will try to download Xcode 10.
Xcode 10 is still in beta. 
True, but you can download it and have both it’ll be out soon!
This is such an interesting topic to explore, request you to make the starter project compilable also could you please mention which Xcode and Swift version it’s compiling, it will be easy to fall along.
as it indicate, xcode 10 swift 4 ios12
Hey @vinaychopra, exactly what @rokurouc said, the project indicates it required Xcode 10, Swift 4.2 and iOS 12.
It’s located here: https://www.raywenderlich.com/5298-reproducing-popular-ios-controls
Right under the green continue button on the left hand side.
Hi, Leamars, thanks for such good course, but my xcode do not compile successfully like I said above. Please help me for that, I start the course from part 3, but I can’t keep moving on in just episode 3.
@leamars Can you please help with this when you get a chance? Thank you - much appreciated! :]
The Xcode & Swift version are mentioned on the bottom of the course content on the left sidebar.
@rokurouc I just downloaded Xcode 10 Beta 6 fresh to see if I could reproduce your problem and I can’t. I don’t think I’ll be able to help you unless you post a link to your project files - perhaps something got messed up between downloading and opening? I recommend you to delete your Xcode Beta (make sure to uninstall completely) and then redownload it and try it again.
