Hey there!

It seems you’ve already found the ticket describing the issue and the workaround. Were you able to follow the steps inside?

Hi There,

I tried the same steps but i got some error related to pods files.

Command which we tried :-

xcodebuild clean build -workspace projectName.xcworkspace -scheme ProjectName OTHER_CFLAGS=“$(inherited) -gen-cdb-fragment-path $(/Users/XYZ/Documents/projectName)/CompilationDatabase”

pushd ~/CompilationDatabase

sed -e ‘1s/^/['$’\n’‘/’ -e ‘$s/,$/'$’\n’‘]/’ *.json > …/compile_commands.json

popd

Error we got :-

PhaseScriptExecution [CP]\ Copy\ XCFrameworks /Users/xyz/Library/Developer/Xcode/DerivedData/xyz-gzdhdfrodipelobkclgbsiutvqvh/Build/Intermediates.noindex/Pods.build/Dev-iphoneos/ABCPOD.build/Script-BAD188F2B3A0595A7525F4143A5D921D.sh (in target ‘ABCPOD’ from project ‘Pods’)
ExtractAppIntentsMetadata (in target ‘ABCPOD2’ from project ‘Pods’)

and we can’t try to disable SIP beacuse we are using our organisation assets.

So do we have any other solution for this?

4

Which step gave you the error?

5

We got the Error when we run below command :-

xcodebuild clean build -workspace projectName.xcworkspace -scheme ProjectName OTHER_CFLAGS=“$(inherited) -gen-cdb-fragment-path $(/Users/XYZ/Documents/projectName)/CompilationDatabase”

pushd ~/CompilationDatabase

sed -e ‘1s/^/[‘$’\n’‘/’ -e ‘$s/,$/’$’\n’‘]/’ *.json > …/compile_commands.json

popd

6

Those are 4 seperate commands. Have you tried running them one at a time?

7

We tried all the comands one by one.

first we hit
xcodebuild clean build -workspace projectName.xcworkspace -scheme ProjectName OTHER_CFLAGS=“$(inherited) -gen-cdb-fragment-path $(/Users/XYZ/Documents/projectName)/CompilationDatabase”

then
pushd ~/CompilationDatabase

8

So pushd gave the error, not xcodebuild? xcodeBuild completed successfully?

9

No Its failing in first command itself :-

xcodebuild clean build -workspace projectName.xcworkspace -scheme ProjectName OTHER_CFLAGS=“$(inherited) -gen-cdb-fragment-path $(/Users/XYZ/Documents/projectName)/CompilationDatabase”
