You should thread big messages like this. Also look three messages up. https://kotlinlang.slack.com/archives/C3PQML5NU/p1629917120375100. You’ll be able to run your app using the “My Mac (Designed for iPad) target but not in the simulator until iosSimulatorArm64 binaries are published.

So should I wait for the dependency? or there is another approach I can do?

If you look closely, you'll see your project sets a target the library doesn't have yet (io_simulator_arm64). The solution is to remove this target until a future version of #ktor supports it.

[Emiliano Schiavone]

yes but removing that I have another issue that I fixed adding the ioSimulatorArm64

[Emiliano Schiavone]

Got embedAndSignAppleFrameworkForXcode issue without ioSimulatorArm64

[louiscad]

Well, at least, you now know what leads to this error message so you can pick your poison until ktor gets a newer release.

[Emiliano Schiavone]

yep, thanks!
