Before wasting time, can I use Ktor in a watchOS app/target?

[Thomas]

Ktor client with iOS engine works for me in a watchOS app

[tylerwilson]

Interesting. May I ask how your gradle is set up? I am using cocoapods integration, which calls the gradle process, passing in the Xcode params. I have something like this:

val buildForWatchARM = project.findProperty("kotlin.native.cocoapods.target") == "watchos_arm"
    if (buildForWatchARM) {
        watchosArm32("watchos32")
        watchosArm64("watchos64")

        val watchosMain = sourceSets.maybeCreate("watchosMain")
        sourceSets["watchos64Main"].dependsOn(watchosMain)
        sourceSets["watchos32Main"].dependsOn(watchosMain)

    } else {
        watchosX64("watchos") // simulator
    }

and then a section like so:

val watchosMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-ios:$ktorVersion")
            }
        }

but when I try to build the framework within AS, I get errors like so:

Could not resolve io.ktor:ktor-client-core:1.6.0.
...
No matching variant of io.ktor:ktor-client-core:1.6.0 was found.

[tylerwilson]

Or are you perhaps linking directly to the generated iOS framework from the watchOS extension?

[Thomas]

Maybe the new watchosX64 target is not supported yet in Ktor

[Thomas]

I am using watchosX86 for simulator

[tylerwilson]

Good point. I am trying simulator first.

[tylerwilson]

sweet. that got me much further.

[tylerwilson]

do you have a specific watchosMain target set up, or do you re-use the iosMain target?

[Thomas]

I have all Ktor code in an appleMain source set which is shared between ios and watchos

[Thomas]

And common / jvm source sets of course

[tylerwilson]

good idea. will look into how to share them. thanks for the help!

[tylerwilson]

Great! Upvoted.

[tylerwilson]

Now can you throw in a PR for maccatalyst? 😉

[Thomas]

Haha unfortunately that's not as easy as this PR

[Thomas]

On the roadmap Mac Catalyst was postponed for later so I am afraid we are not going to see support anytime soon

[Thomas]

For my project I am considering using Compose UI instead which is JVM (so not Kotlin/Native)

[Thomas]

#compose-desktop

[tylerwilson]

That does look pretty cool. Have to get into it. I might look into doing a macOS SwiftUI version of our app, then at least I can use the shared code compiled as a pure macOS framework.

[tylerwilson]

@Thomas Well done on the PR. Approved and Merged! Anxious to get Ktor 1.6.1 now. 🙂
