Extending • Swift-class component returns nil

Extending with custom components doesn’t work for Swift classes. There is an issue in JasonComponentFactory in method build:withJSON:withOptions::

NSClassFromString(componentClassName) returns nil for Swift classes, because Swift class name have a different format: <appName>.<className> or <appName>_<targetName>.<className> instead of just <className> in Obj-C classes.

Therefore component class names must have a prefix for Swift classes, i.e. MyAppName.JasonSuperComponent

yes, @objc(MySwiftClass) works fine

Try this in your swift code

All swift classes use the Product Module Name a dot and the classname for their namespace (Module.Class). If you wanted to use “MySwiftClass” name for the class within your Objective-C code; you can add @objc(MySwiftClass) annotation to expose the same swift class name (without the module):

@objc(MySwiftClass)
class MySwiftClass{
    ...
}

Then

Class myClass = NSClassFromString(@"MySwiftClass");

Will contain the class instead of being nil.
