xcode12 - 升级到 Xcode 12 :ld: building for iOS Simulator, 但在为 iOS 构建的 dylib 中链接后出现问题，架构 arm64

Question

我将 Xcode 升级到 Xcode 12，并构建了我的项目。
首先，它出现如下错误:

ld: building for iOS Simulator, but linking in dylib built for iOS, file '/Users/ethanli/Documents/Aspira/RA.com4iOS/RA.com4iOS/source/ReserveAmerica/ReserveAmerica4/External/Mapbox/MapboxMobileEvents.framework/MapboxMobileEvents' for architecture arm64

我通过在 Build Settings 中向 Excluded Architecture 添加“arm64”消除了这个错误。引用

但是……又出现了一个错误:

error: Build input file cannot be found: '/Users/ethanli/Library/Developer/Xcode/DerivedData/ReserveAmerica4-cgnruuknmgycgrbadguodtkwspmy/Build/Products/DEBUG-iphonesimulator/ReserveAmerica4.app/ReserveAmerica4' (in target 'ReserveAmerica4' from project 'ReserveAmerica4')

我去Finder的路径，“ReserveAmerica4”真的不存在。
有没有办法解决这个问题？

Answer 1

我解决了这个错误。
根本原因是 Xcode 12 不允许为模拟器构建 arm64 架构。我们应该为模拟器build设置 x86_64。

在目标build设置选项卡中将“仅构建事件架构”设置为"is"；

为模拟器设置 x86_64:
