未能運行'lipo'，Lib具有相同的體系結構

所以我運行下面的命令：

的設備

xcodebuild 
      -project MyAppLib.xcodeproj 
      -sdk iphoneos 
      -target $PRODUCT_FRAMEWORK 
      -configuration Release clean build

的模擬器

xcodebuild 
      -project MyAppLib.xcodeproj 
      -sdk iphonesimulator 
      -target $PRODUCT_FRAMEWORK 
      -configuration Release clean build

然而，當我嘗試運行lipo：

lipo -create build/Release-iphonesimulator/MyAppLib.framework/MyAppLib 
     build/Release-iphoneos/MyAppLib.framework/MyAppLib 
    -output MyAppLib.framework

我得到一個錯誤：

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: build/Release-iphonesimulator/MyAppLib.framework/MyAppLib and build/Release-iphoneos/MyAppLib.framework/MyAppLib have the same architectures (i386) and can't be in the same fat output file

在Xcode我的成功建立，但來自CLI都具有相同的結構。

$ file MyAppLib.framework給我：

MyAppLib.framework: Mach-O universal binary with 4 architectures: [i386: current ar archive] [arm_v7: current ar archive] [x86_64: current ar archive] [arm64] 
MyAppLib.framework (for architecture i386): current ar archive 
MyAppLib.framework (for architecture armv7): current ar archive 
MyAppLib.framework (for architecture x86_64): current ar archive 
MyAppLib.framework (for architecture arm64): current ar archive

如果我嘗試運行只爲一個平臺，打造的是成功了，但是我得到了奇怪的框架，我甚至不能探索它：

我不知道Xcode會用所示的設置吐出所有架構。我懷疑你正在運行一個構建階段腳本。如果不是：將'i386，x86_64'添加到您有效的體系結構中，並將'僅生成活動體系結構'設置爲'釋放'爲'否'。另外：什麼是'文件'輸出。 Xcode構建或CLI構建？另外，「奇怪的框架」有什麼問題？ – shallowThought

@shallowThought我只爲'調試版和發佈版'構建僅有''YES''。我還發布了'多平臺腳本'。我是否需要爲iOS和模擬器運行構建靜態框架？在奇怪的框架下，我的意思是'MyAppLib.framework'是一個文件而不是文件夾。 – snaggs

如果您想在應用程序中使用此庫，您希望能夠在設備上使用它，並且還可以在模擬器中調試您的應用程序。所以是的，你確實想要建立設備和模擬器。 – shallowThought

解決方案：

你沒有問題。在構建項目後出現的MyAppLib.framework是您的靜態庫，包含所有必需體系結構的片。

構建項目後無需使用lipo。

問題：

構建腳本「自動」建立你的目標兩次，一次設備和一次模擬。之後，它使用lipo將兩個構建文物合併到一個胖文庫（make_fat_library）。

然後它會將結果周圍：

#Ensure that the framework is present in both platform's build directories

其結果是，你有一個脂肪LIB框架，建立兩者的目錄。

現在你正試圖合併這兩個（已經合併）脂肪庫。由於兩者都包含相同的切片，因此會出現錯誤。
