Bridging Header issue - 'MyClass' is unavailable: cannot find Swift declaration for this class

Question

I have visited this links -

MyClass is unavailable: cannot find Swift declaration for this class - Release Build Only

Adding Linked or Embedded Swift Framework: 'MyClass' is unavailable: cannot find Swift declaration for this class

Swift: using private framework

But none of the above links helped me to solve my problem.

I am developing an App using objective-c, in the app I am integrating ios-charts whose framework is developed in swift.I have merged the project as given in the README file. After integrating i have created a MyClass.swift file and then inherited the MyClass.swift file with a Class which is defined in charts.framework.But this is rising an error

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

Does anyone help me to solve this error? Any suggestions??

Answer 1

This may be due to possibility that you are building for device and using for simulator and vice-versa. Please check this. This is very important thing. If you compiled or build framework for device, it will not work on simulator.

Answer 2

My fix for this problem was to change the deployment target of the framework from my device to “Generic iOS Device” and then rebuild the framework.

Answer 3

Try adding @objc infront of the MyClass declaration (i.e. @objc class MyClass {...})
