Hi folks, quick question. How come i can import java.util.UUID in commonMain?

In commonMain:

public expect class UUID

In jvmMain

public actual typealias UUID = java.util.UUID

In another part in commonMain:

import java.util.UUID

public data class Account(
    public val uuid: UUID,
    public val number: String,
    public val firstName: String,
    public val lastName: String,
    public val identityKey: String
)

You cannot and you should not. Have a look at https://github.com/hfhbd/kotlinx-uuid or https://github.com/benasher44/uuid

Actually i was trying to play with expect and actual

[Grégory Lureau]

Oh ok, clearer after you edited the message. You don't want to import java.util; you want to import your expect UUID

[George]

Yup that's what i thought, thanks for the help. For some reason intelij did not import automatically my expect . So i just typed manual the import and it worked lol . Still pretty new to KMM 🙂

Another quick question is it ok to declare my actual impl with typealis as i did in jvmmain?

[Grégory Lureau]

Yes it's totally fine.
You have some constraints when using a typealias, the method needs to match the expect class, so if you support more than just jvm, you will probably need a mapping class instead of just a typealias at some point.

Really thanks for the info :)
