I've recently updated to Xcode 14 for my KMM project and I now run into this build error when syncing gradle.
shared/build/cocoapods/synthetic/IOS/Pods/Pods.xcodeproj: error: Signing for "gRPC-C++-gRPCCertificates-Cpp" requires a development team. Select a development team in the Signing & Capabilities editor. (in target 'gRPC-C++-gRPCCertificates-Cpp' from project 'Pods')
I'm using Firebase and am including the pods as dependencies in my shared build.gradle file.
kotlin {
...
cocoapods {
...
ios.deploymentTarget = "15.0"
podfile = project.file("../iosApp/Podfile")
framework {
baseName = "shared"
}
xcodeConfigurationToNativeBuildType
val firebaseVersion = "9.6.0"
pod("FirebaseCore") { version = firebaseVersion }
pod("FirebaseAuth") { version = firebaseVersion }
pod("FirebaseFirestore") { version = firebaseVersion }
pod("FirebaseCrashlytics") { version = firebaseVersion }
pod("FirebaseAnalytics") { version = firebaseVersion }
}
...
}
I have a team setup and if I open Xcode and go to the Pods project, select gRPC-C++-gRPCCertificates-Cpp, then add my team to it, the project builds fine from Xcode.
However, this doesn't fix the gradle issue as it seems to use its own temporary project file when syncing (in shared/build/cocoapods/synthetic/IOS/Pods/Pods.xcodepro)
Is there any way to add my team to the gradle sync build?
As a temporary work around, I've switched back to Xcode 13.4.1 which doesn't have this problem.
This will be fixed in Kotlin 1.8.0 but in the meantime here is a workaround (from https://youtrack.jetbrains.com/issue/KT-54161)
First create the directories buildSrc/src/main/kotlin in the root of your project. In buildSrc create the file build.gradle.kts and add the following contents.
plugins {
`kotlin-dsl`
}
repositories {
mavenCentral()
google()
}
dependencies {
implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.20")
implementation("com.android.tools.build:gradle:7.3.1")
}
Then create the file PatchedPodGenTask.kt in buildSrc/src/main/kotlin. Add the following to it.
import org.gradle.api.Project
import org.gradle.api.logging.Logger
import org.gradle.api.provider.Provider

Find the line that says config.build_settings["DEVELOPMENT_TEAM"] = "..." and replace ... with your actual dev team ID.
Finally, in the build.gradle.kts file of the module you want to apply it (mine was the shared module) add the following
// @TODO: This is a hack, and we should remove it once PodGenTask is fixed or supports adding suffixes in the official Kotlin plugin
tasks.replace("podGenIOS", PatchedPodGenTask::class.java)
Clean your project and re-sync Gradle. The patch should be applied and work with Xcode 14
