Hello :wave: Has anyone had experience creating extension functions for Floats in `common` which then translate to appropriate usages for Swift/iOS?

For example:

```data class Measurement(val type:String, val value:Float)

fun Float.metres() = Measurement("Metre", this)```
What I currently end up with being generated on the iOS side in the header file is given the extension function lives in the file `FloatExt.kt`:

```__attribute__((objc_subclassing_restricted))
__attribute__((swift_name("FloatExtKt")))
@interface FloatExtKt : KotlinBase
+ (Measurement *)metres:(float)receiver __attribute__((swift_name("metres(_:)")));
@end```
Which suggests that it’s not an extensions on the iOS “float” type but accessible via `FloatExtKt.metres()`  :thinking_face:

Extensions on Objective-C classes are not supported in the interop, so you end up with this.

For these kind of things, I always have a Swift file with Swift extensions that wrap these to be used nicely anywhere else in the project.
