conference-app-2020: [iOS] Build failed with gradle task

Overview (Required)

• iOS app build failure with gradle task

Steps To Reproduce

1. Clone the repository. commit: 20f75ee7
2. Run make init in the iOS App directory and open the workspace.

cd ios-base && make init && open DroidKaigi\ 2020.xcworkspace

1. Edit TARGETS > DroidKaigi 2020 > Build Phases > Build Kotlin Modules .

-  BUILD_IOS=true ./gradlew :ios-combined:$KN_LIBRARY_BUILD_TASK -PXCODE_CONFIGURATION=${CONFIGURATION}
+  BUILD_IOS=true ./gradlew assembleDebug --stacktrace :ios-combined:$KN_LIBRARY_BUILD_TASK -PXCODE_CONFIGURATION=${CONFIGURATION}

1. Run build.
2. See error
