Compose Multiplatform iOS加载图片报错：找不到coil-network-ktor依赖

问题现象 #

执行Compose Multiplatform项目同步时触发如下错误：

:composeApp:iosArm64Main: Could not find io.coil-kt.coil3:coil-network-ktor:3.0.0-rc01.
Required by:
project :composeApp

用户当前的版本配置文件（libs.versions.toml）：

[version]
kotlin = "2.0.20"
coil = "3.0.0-rc01"
ktor = "3.0.0"

[libraries]
ktor-core = { module = "io.ktor:ktor-client-core", version.ref = "ktor" }
ktor-client-darwin = { module = "io.ktor:ktor-client-darwin", version.ref = "ktor" }
ktor-client-okhttp = { module = "io.ktor:ktor-client-okhttp", version.ref = "ktor" }
ktor-client-js = { module = "io.ktor:ktor-client-js", version.ref = "ktor" }
ktor-client-curl = { module = "io.ktor:ktor-client-curl", version.ref = "ktor" }
ktor-client-winhttp = { module = "io.ktor:ktor-client-winhttp", version.ref = "ktor" }
coil-compose = { module = "io.coil-kt.coil3:coil-compose", version.ref = "coil" }
coil-compose-core = { module = "io.coil-kt.coil3:coil-compose-core", version.ref = "coil" }
coil-network-ktor = { module = "io.coil-kt.coil3:coil-network-ktor", version.ref = "coil" }
coil-mp = { module = "io.coil-kt.coil3:coil", version.ref = "coil" }

Gradle依赖配置：

sourceSets {
        
        androidMain.dependencies {
            implementation(compose.preview)
            implementation(libs.androidx.activity.compose)

            //coil
            implementation(libs.ktor.client.okhttp)


        }

        iosMain.dependencies {

            //coil
            implementation(libs.ktor.client.darwin)
        }

        commonMain.dependencies {
            implementation(compose.runtime)
            implementation(compose.foundation)
            implementation(compose.material)
            implementation(compose.ui)
            implementation(compose.components.resources)
            implementation(compose.components.uiToolingPreview)
            implementation(libs.androidx.lifecycle.viewmodel)
            implementation(libs.androidx.lifecycle.runtime.compose)

            //coil
            implementation(libs.ktor.core)
            implementation(libs.coil.compose.core)
            implementation(libs.coil.mp)
            implementation(libs.coil.network.ktor)
            implementation(libs.coil.compose)
        }
    }

问题原因 #

Coil 3.0.0-rc01版本里，coil-network-ktor模块的ID做了版本区分：原来的io.coil-kt.coil3:coil-network-ktor已经不再使用，现在需要根据Ktor版本选择对应模块：

• 适配Ktor 3.x的模块是coil-network-ktor3
• 适配Ktor 2.x的模块是coil-network-ktor2

你的项目使用的是Ktor 3.0.0，所以必须用coil-network-ktor3，否则Gradle无法找到对应依赖。

修复方法 #

直接修改libs.versions.toml里的coil-network-ktor配置：

coil-network-ktor = { module = "io.coil-kt.coil3:coil-network-ktor3", version.ref = "coil" }

修改完成后重新执行Gradle同步即可。
