Script integrating OCLint into XCode. Put it in "Run script" build phase.

gistfile1.sh

source ~/.bash_profile
cd ${SRCROOT}
xcodebuild clean
xcodebuild | xcpretty -r json-compilation-database
oclint-json-compilation-database -- -report-type xcode

I was recently having some trouble getting this working on a project using Xcode 10 and OCLint 0.13.1. Here's a summary of some of the errors I saw and how I resolved them:

• error: accessing build database "/Users/tyler.milner/Library/Developer/Xcode/DerivedData/<project_name>/Build/Intermediates.noindex/XCBuildData/build.db": disk I/O error
  • Solved by switching from the New Build System to the Legacy Build System (File --> Workspace Settings in Xcode).
• oclint: error: one compiler command contains multiple jobs:
  • Solved by adding the COMPILER_INDEX_STORE_ENABLE=NO build flag to my main xcodebuild step.
• oclint: Not enough positional command line arguments specified!
  • Solved by adding unset LLVM_TARGET_TRIPLE_SUFFIX to the top of the script.

I've got a working version of the script that contains the above fixes in my fork. Also including it below (again, you will need to replace <project_name> with appropriate values and likely tweak the -exclude flags):

source ~/.bash_profile

unset LLVM_TARGET_TRIPLE_SUFFIX

xcodebuild -scheme <project_name> -workspace <project_name>.xcworkspace clean
xcodebuild -scheme <project_name> -workspace <project_name>.xcworkspace COMPILER_INDEX_STORE_ENABLE=NO | xcpretty -r json-compilation-database --output compile_commands.json

maxPriority=15000
oclint-json-compilation-database -exclude Pods -exclude build -- -report-type xcode -max-priority-1=$maxPriority -max-priority-2=$maxPriority -max-priority-3=$maxPriority

worked with Xcode 11.2.1

source ~/.bash_profile

unset LLVM_TARGET_TRIPLE_SUFFIX

xcodebuild clean
xcodebuild COMPILER_INDEX_STORE_ENABLE=NO | xcpretty -r json-compilation-database --output compile_commands.json
