4/3/2023 0 Comments Swift code in objective c![]() This way you can update colors, default text, web service urls for whole app in one place. In Objective-C, you can use them like this: NSString appklicationId Constant parseApplicationId NSString clientKey Constant parseClientKey UIColor greenColor Constant appGreenColor Share Follow edited at 7:39 qix 6,898 1 53 65 answered at 14:27 rintaro 51. Let AppGreenColor = UIColor(red: 0.2, green: 0.7, blue: 0.3 alpha: class Constant: NSObject įor use in Objective-C files add this when you need to use constants: #import "ProjectModuleName-Swift.h" For example, many Objective-C frameworks expose classes that you are expected to subclass.Īs of now, IMHO, the best way is something like this: let ParseApplicationId = "xxx" It requires a lot less code performing the same takes when compared to Objective-C. If you use an Objective-C API that needs to process your data, or you need to fit your data model into an existing class hierarchy defined in an Objective-C framework, you might need to use classes and class inheritance to model your data. Swift is easy to Read and Write because it is a clean and expressive language that has simplified Syntax and Grammar. ![]() Use Classes When You Need Objective-C Interoperability ![]() see the documentation, which states in part: ![]() For modern programmers who works on languages like Python or JavaScript, this is a very complex syntax. Consider the code below for writing a simple string variable, called NSString, in Objective-C. Sad to say, you can not expose struct, nor global variables to Objective-C. Winner: Swift Syntax Objective-C is very difficult to learn, as it has some of the old C syntax.
