Create a cocoa touch framework can not use in main project

I want to learn cocoa touch framework, and I have code same as lots google result, but all not work.

I want to create a reuse code that can do write and read json file, and can called by main project app, so I create a simple cocoa touch framework just for test, I have drag the framework into main project, added it in embedded binaries, but when I build app, it always appears error message at [let a = testClass] this line in main project and below is error message:

'testClass' is unavailable: cannot find Swift declaration for this
class

is anywhere I make mistake?

code of cocoa touch framework:

import Foundation

public class testClass : NSObject 

 public static func tData() -> String 
 return "path"

code of app :

import UIKit
import test

override func viewDidLoad() 
 super.viewDidLoad()
 // Do any additional setup after loading the view, typically from a nib.

 let a = testClass

let a = testClass() or let a: testClass = whatever NSObject you have

since you have declared tData as static you can directly access by using class name like testClass. tData()

I change this line to : testClass.tData(), but shows error message : 'testClass' is unavailable: cannot find Swift declaration for this class.......But I have import test already......

Is your framework name test? because if not make sure you import the library correctly

I think you should try adding the init() method to your testClass

public override init() 
 super.init()

Try removing the lib and adding it again after adding the init, and of course don’t forget the clean and build first the lib then the project

– Arie Pinto
Nov 13 '18 at 12:31

Did it. After 20 min try it again and again(delete cocoa touch project and create a new one), still the same error message...,

– Simon
Nov 13 '18 at 13:00

Ok, try this then, delete your library from the project, and instead of trying to add it from outside, create it directly inside your project by going File->New->Target->Cocoa Touch Framework, this should guarantee the link between the project and the lib, and then just add your code directly in the lib which is inside the project.
