@chensisi0730,

We are already aware of this issue, and we are diligently working towards a resolution. Kindly consider employing the officially supported Bazel version 6.1.1, as indicated in the .bazelversion file.

Furthermore, We recommend making adjustments to the configuration in the "Configs/MediaPipe.tulsigen" file located under the "MediaPipe.tulsiproj" folder.

As a temporary solution, Prepend an "@" symbol before each buildTargets path starting from Line 26, as illustrated below:

"buildTargets" : [
"@//mediapipe/examples/ios/facedetectioncpu:FaceDetectionCpuApp",
"@//mediapipe/examples/ios/facedetectiongpu:FaceDetectionGpuApp",
"@//mediapipe/examples/ios/faceeffect:FaceEffectApp",
"@//mediapipe/examples/ios/facemeshgpu:FaceMeshGpuApp",
"@//mediapipe/examples/ios/handdetectiongpu:HandDetectionGpuApp",
"@//mediapipe/examples/ios/handtrackinggpu:HandTrackingGpuApp",
"@//mediapipe/examples/ios/helloworld:HelloWorldApp",

Bazel version 6.1.1

Bazel version 6.1.1 have bug , #4296 Because I modified the source code of bazel during command line build , it was successful. Should I use custom bazel in Xcode ?
