升級Xcode12后，編譯項(xiàng)目時(shí)，可能會(huì)出現(xiàn)以下錯(cuò)誤：
building for iOS Simulator, but linking in object：
building for iOS Simulator, but linking in object ... file built for iOS, for architecture arm64

產(chǎn)生這些報(bào)錯(cuò)的根本原因是新版本的Xcode 12更改了編譯架構(gòu)的設(shè)置方式：
舊版本的Xcode編譯架構(gòu)設(shè)置方式: 用Xcode打開項(xiàng)目 -> Project -> PROJECT -> Build Setting ->
- 首先在Architectures -> Valid Architectures -> 設(shè)置可用的編譯架構(gòu)指令集
- 然后在User-Defined -> EXCLUDED_ARCHS -> 設(shè)置排除的編譯架構(gòu)指令集
而新版Xcode12的編譯架構(gòu)設(shè)置方式: 用Xcode打開項(xiàng)目 -> Project -> PROJECT -> Build Setting ->
- 首先在Architectures -> Excluded Architectures -> 排除的編譯架構(gòu)指令集
- 然后在User-Defined -> VALID_ARCHS -> 設(shè)置可用的編譯架構(gòu)指令集
因此，解決上述問題的方案就是在新版的Xcode12中設(shè)置：
- 在Architectures -> Excluded Architectures -> 設(shè)置排除的編譯架構(gòu)指令集為"arm64"。（建議只設(shè)置Debug模式，Release模式還是要支持arm64的，否則打包后無法在真機(jī)上海安裝）
- 同時(shí)，刪除
User-Defined中的VALID_ARCHS欄，即可用的編譯架構(gòu)指令集的設(shè)置（操作方法：選擇PROJECT -> Build Setting ->User-Defined ->選中VALID_ARCHS，直接按Delete鍵）。
