【问题描述】：

我有一台 M1 MacBook Air。

在 Xcode 中为模拟器构建时，我看到以下警告和错误：

ld: warning: ignoring file /Users/kon/Library/Developer/Xcode/DerivedData/InvisibleComputersApp-hktlnhvaoskvxkcdhnahydmbodzw/Build/Products/Debug-iphonesimulator/GoogleSignIn.o, building for iOS Simulator-x86_64 but attempting to link with file built for unknown-arm64

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

这听起来像是 Xcode 试图构建一个 x86 二进制文件？为什么它甚至试图这样做，不是基于 M1 Macs 的模拟器 arm 吗？

我该怎么做

【问题讨论】：

检查项目设置和 .xcconfig 文件 - 可能有 x86_64 架构集。
@Asperi 这会是什么样子？
在“架构”下显示“标准架构 (arm64, armv7) - $(ARCHIS STANDARD)
嘿@Asperi - 是的，我找到了一个设置。由于其他一些问题，我之前一直在关注堆栈溢出答案以禁用模拟器的 ARM 构建......现在切换到 M1 Mac 后，这让我很痛苦。
得到了同样的结果。你发现了吗？

【解决方案1】：

您可以尝试打开 Xcode 并勾选“使用 Rosetta 打开”。

退出 Xcode
转到您的应用程序文件夹
右键单击 Xcode，然后选择“获取信息”
选中“使用 Rosetta 打开”
打开 Xcode
