我在我的一個混合 iOS 專案中運行推斷。以下是命令，
infer --keep-going -o ./Infer --skip-analysis-in-path Pods -- xcodebuild clean build -workspace Codes/Project/Project.xcworkspace -scheme Main -configuration Release SWIFT_OPTIMIZATION_LEVEL=-Onone
在構建日志的末尾出現以下錯誤。

如何解決？
infer version = 1.1.0_1
Xcode: 12.4
MacBook Pro, 2012 model
macOS: Catalina, 10.15.7
uj5u.com熱心網友回復：
以下步驟解決了我的問題，
第 1 步：使用以下命令升級推斷版本，
brew upgrade infer #worked with version 1.1.0_1
第 2 步：compile_commands.json使用以下命令從正確的專案目錄創建檔案，
xcodebuild -workspace Codes/Project/Project.xcworkspace -scheme Main -sdk iphoneos14.4 COMPILER_INDEX_STORE_ENABLE=NO OTHER_CFLAGS="-DNS_FORMAT_ARGUMENT(A)= -D_Nullable_result=_Nullable" | tee xcodebuild.log | /usr/local/bin/xcpretty -r json-compilation-database -o compile_commands.json
這里你要根據你自己的改變workspace、scheme、sdk、xcpretty location值。如果未安裝 xcpretty，則必須先使用sudo gem install xcpretty.
第 3 步：在實際的推斷命令中使用創建的檔案，例如，
infer run --keep-going --skip-analysis-in-path Pods --compilation-database-escaped compile_commands.json
