An invalid depfile error in Xcode occurs when the dependency file specified in the build settings is incorrect or cannot be found. The dependency file is a list of files that are required to build a target, and it is used to determine whether a target needs to be recompiled or not.
To resolve this error, you need to make sure that the depfile specified in your Xcode project’s build settings is valid and points to the correct file. Here’s how you can do it:
- Open your Xcode project.
- Select your target in the project navigator.
- Go to the “Build Settings” tab.
- Search for the “Dependencies File” setting.
- Make sure the value of the “Dependencies File” setting is correct.
For example, if your depfile is named MyApp.d and it is located in the same directory as your Xcode project file, you should set the value of the “Dependencies File” setting to $(SRCROOT)/MyApp.d.
If the depfile specified in the build settings does not exist or is incorrect, you can either remove the depfile setting or update it with the correct path to resolve the error.
