Hello All,
Need a little help.
There is a custom method written in Swift fun static sendToTailor(name : String) . I need to call this method in IOS main of KMM, how can I do that ?

You'll need to add/use cinterop and write a Obj-C wrapper for it.

With this particular method, using the @objc annotation in your swift code should suffice for swift to write all the necessary wrappers.

@streetsofboston I have written this

import Foundation

@objc class TailorBridge: NSObject {
    @objc static func sendToTailor(name: String, payload: [String: Any]) {
        print("Name: \(name), Value: \(payload)")
    }
}

actual object TailorBridge {
    actual fun sendToTailor(
        name: String,
        payload: Map<String, Any>
    ) {
        val nsDictionary = payload.toNSDictionary()
        TailorBridge().sendToTailor(name, nsDictionary)
    }
}

But in actual its not able to resolve

You created the Obj-C wrappers through the @objc annotations. You'll still need to add and configure KMP's cinterop functionality so that these Obj-C wrappers are visible/accessible by KMP.

For cinterop, you can take look here:
https://kotlinlang.org/docs/native-c-interop.html
and, a bit old but it helped me quite a bit, https://medium.com/kodein-koders/create-a-kotlin-multiplatform-library-with-swift-1a818b2dc1b0

Still not able to, may be I am missing some configuration
