Compose Multiplatform配置iOS时SqlDelight依赖报错求助

将原无iOS端的Jetpack Compose应用转为Compose Multiplatform项目，配置iOS共享模块时构建失败，出现以下错误：

Cannot access class 'app.cash.sqldelight.db.SqlSchema'. Check your module classpath for missing or conflicting dependencies
Unresolved reference: SqlDriver

解决方案（针对SqlDelight 2.0.1版本） #

1. 补充CommonMain的SqlDelight核心依赖 #

SqlSchema和SqlDriver的基础定义位于SqlDelight核心runtime库中，当前配置的commonMain缺少该依赖，需添加：

// 在commonMain的dependencies块中添加
implementation(libs.sqldelight.runtime)
// 若使用硬编码版本，对应2.0.1：
// implementation("app.cash.sqldelight:runtime:2.0.1")

2. 验证iOS驱动依赖的正确性 #

确保libs.sqldelight.native.driver指向正确的包坐标：app.cash.sqldelight:native-driver:2.0.1，检查项目根目录的libs.versions.toml文件，确认版本与SqlDelight插件版本一致。

3. 修正Schema生成路径 #

当前配置中schemaOutputDirectory的路径与packageName不匹配，会导致生成的Schema类无法被正确识别，修正路径：

schemaOutputDirectory.set(file("src/commonMain/sqldelight/com/vboxcomm/shared/database"))

4. 清理缓存并重新构建 #

执行以下步骤清除缓存并同步项目：

• 运行Gradle任务：./gradlew clean
• 在IDE中点击"Sync Project with Gradle Files"
• 重新执行构建任务

5. 排查依赖冲突 #

运行./gradlew dependencies命令，查看commonMain和iosMain中SqlDelight相关依赖的版本是否统一，若存在不同版本的依赖，需强制统一为2.0.1版本。
