Hi guys! I'm using Swift in developing applications for iOS. Currently, I'm interested in learning Objective-C to build applications. However, when I create a project with Obj-C, I found out that, there are some differences between using "Obj-C in iOS Dev" and "Obj-C in MacOS CommandLine". For instance: declaring method; iOS Dev Environment: -(void)getFunc {..} macOS Dev Environment: void getFunc() {...} You can see here, there are -(void) and void only. Anyway, can you recommend some documents to study Objective-C? Thank you for spending time for my post! Have a great day! Best regard from Vietnam!
