Hello everyone Someone here already had problems with XCode kotlinlang #multiplatform

Hello everyone! Someone here already had problems with XCode SwiftUI previews while using KMM? The preview updates are paused every time for me, it seems that it's only happening in KMM projects. I already set all my scripts to run only on install but that doesn't solve the problem.

There's a known issue around static frameworks, such as cocoapods plugin creates by default. Try this https://github.com/JetBrains/kotlin-native/issues/3059#issuecomment-577041551

@Charles Prado The second answer solve the same problem('The preview updates are paused every time') for me https://stackoverflow.com/questions/58490010/swiftui-automatic-preview-updating-paused-always Now my project could be automatic update preview ui now when using KMM with dynamic framework(by cocoapods plugin)

Copy code

targets.withType<org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget> {
        binaries.withType<org.jetbrains.kotlin.gradle.plugin.mpp.Framework> {
            isStatic = buildForDevice
        }
    }

Configs in Xcode for KMM lib

Copy code

noPodspec()
val podFile = file("kmmlib.podspec")
podFile.writeText(
    podFile.readText().replace(
        oldValue = "spec.static_framework         = ${buildForDevice.not()}",
        newValue = "spec.static_framework         = $buildForDevice"
    )
)

Hey @wuseal, I ended up applying this solution too. Fixed for me as well. Tks 🙂
