Can I know more about why 1.9.20 had to break its APIs by preventing methods with default parameters in KMP? What were the limitations?

[kevin.cianfarini]

Can you be more specific? I use default params in common code in 1.9.21 with no issue.

[Benoit Quenaudon]

They’re not available anymore in expect/actual

[Benoit Quenaudon]

Or is it a bug?

[Benoit Quenaudon]

In any case it prevents me from typealiasing to OkHttp.Response because it has default parameters

[russhwolf]

Did that work prior to 1.9.20? I think the idea is the default param is redundant in the actual because it's present in the expect.

[Benoit Quenaudon]

It worked before, yes. Bumping Kotlin forces us to move away from the typealias

[russhwolf]

Does it do what you want if you drop the default param from the actual?

[Benoit Quenaudon]

The point is I don’t wanna have to write the actual. I was doing actual typealias GrpcResponse = okhttp3.Response before and I cannot anymore.

I'm not clear what the typealias issue is specifically but there were some restrictions added around expect classes as part of stabilizing KMP.

Not sure if you'll find your specific issue or not
