xcode - 无法在 XCode 中使用 Cocoapods 归档 Kotlin Native

问题描述

我尝试在 XCode 12 中存档一个项目，该项目引用带有 cocoapods 插件的 Kotlin Native 框架，但它失败并显示这样的消息（使用 iPhone SE 构建存档）

Ignoring file *MyFramework*, building for iOS-armv7 but attempting to link with file built for iOS-arm64

Undefined symbol: _OBJC_CLASS_$_... (for armv7)

我在项目的 Podfile 中将我的框架引用为本地 pod（使用:pathand :modular_headers => true）

据我了解，我必须构建一个胖框架来包含两者armv7，arm64但是如何使用 Kotlincocoapods插件来管理它？

以下是一些建议链接，但我无法将它们放在一起

解决方案

实际上不是一个真正的解决方案 - 基于接受的答案，我刚刚放弃armv7支持将其添加到Excluded Architectures

标签： xcodegradlecocoapodskotlin-native

解决方案

building for iOS-armv7 but attempting to link with file built for iOS-arm64

看起来您正在尝试为 armv7 存档，它（我认为）是 32 位 ios，或者可能是手表等。大多数应用程序只需要 arm64，而您的 Xcode 框架将只有 arm64，根据以下：

final def iOSTarget = System.getenv('SDK_NAME')?.startsWith("iphoneos")  \
         ? presets.iosArm64 : presets.iosX64

如果您只需要 arm64，并且它只是一个 iOS 应用程序，那么您可以在构建中禁用 armv7 架构。或者，您可以尝试组合ios()目标。

我们在这里有一个功能示例：https ://github.com/touchlab/KaMPKit

它使用 cocoapods 插件的一个分支，但除此之外isStatic，它基本上是相同的插件。
