swift - Cannot access Swift Framework in Objective-C

Question

Create Swift Framework ,

Geolens.swift

When i am trying to access in Objective-C project , cannot call 2 methods

createuser & startSessionForUser

Getting error like this

Method cannot be marked @objc because the type of the parameter cannot be represented in Objective-C

Answer 1

Your problem is in errorCode: Int? in UserCompletionBlock.

Int is value type, and Objective C cannot represent Optional of value type, only reference types such as class will.

So you have to either:

1. get rid of optionality
2. use reference type, such as NSNumber or your own wrapper
3. drop this parameter completely

Answer 2

Add @objc:

@objc public func createUser(...) { ... }
@objc public func startSessionForUser(...) { ... }

Answer 3

If you want the methods to be accessible in Obj-C also please make sure you add @objc public in definition of all the methods. Just the way you did it in didRegister... and didFailedToRegisrer... methods in your class.

Happy Coding...
