How to import existing Objective C classes in Swift

ios, swift

Solution

Posting the answer if it helps some one facing the same issue.

I found that a pretty straight forward solution for How to do this is given in the iOS Developer Library. Please refer to the following link:

https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html#//apple_ref/doc/uid/TP40014216-CH10-XID_75

Apple Doc says:

To import a set of Objective-C files in the same app target as your Swift code, you rely on an Objective-C bridging header to expose those files to Swift. Xcode offers to create this header file when you add a Swift file to an existing Objective-C app, or an Objective-C file to an existing Swift app.

So I created `MyApp-Bridging-Header.h` file and just added the following line:

#import "MyModel.h"

Now it lets me use the model in my `ViewController.swift` as follows:

var myModel = MyModel()
myModel.name = "My name"
myModel.dobString = "11 March,2013"
println ("my model values: Name: \myModel.name and dob: \myModel.dobString")

FYI to anyone who is trying to figure this out. If you have to create the bridging file from scratch, you also have to specify a path to it in Build Settings > Swift Compiler > Objective-C Bridging Header.

Problem

I had been messing around with Swift for a while in XCode 6.0 DP to use it in my existing project. I am trying to access MyModel.h(My existing Objective C Model object) from my ViewController.swift file. I wanted to import `#import "MyModel.h"` to my Swift file. But I could not find how this can be done.
