Encountering the Xcode warning “The Copy Bundle Resources build phase contains this target’s Info.plist file” can be perplexing for iOS developers. This seemingly innocuous message can sometimes lead to unexpected app behavior, including crashes or rejected app submissions. Understanding why this warning appears and how to resolve it is crucial for a smooth development process. This article dives deep into the intricacies of this warning, providing actionable solutions and best practices to ensure your Xcode projects remain clean and error-free.
Understanding the Info.plist File
The Info.plist (Information Property List) file is a structured XML file that contains essential configuration data for your iOS app. This includes details like your app’s name, bundle identifier, version number, supported device orientations, and required system frameworks. It acts as a bridge between your app and the operating system, providing critical information needed for proper execution. Mishandling this file can have significant consequences.
The Info.plist file plays a vital role in various aspects of app development, from defining app capabilities to managing app icons and launch screens. Its correct placement and configuration are essential for ensuring a seamless user experience.
Why the Warning Appears
The “Copy Bundle Resources” build phase is designed to copy necessary resources into your app bundle. Including the Info.plist file here is redundant and can lead to conflicts. Xcode detects this redundancy and issues the warning. While the warning itself might not always cause immediate problems, it indicates a potential misconfiguration that can manifest as unexpected issues later on, especially when dealing with complex project setups or multiple targets.
One common scenario that triggers this warning is accidentally adding the Info.plist file to the “Copy Bundle Resources” build phase. This can happen when dragging and dropping files or when configuring build phases manually. Another potential cause is using outdated project templates or migrating projects between different Xcode versions.
Resolving the Warning
Fixing the warning is generally straightforward. Open your project’s build phases, locate the “Copy Bundle Resources” phase, and remove the Info.plist file from the list. Xcode automatically handles the inclusion of the Info.plist file in the app bundle, so manually adding it is unnecessary. This simple step ensures your project adheres to best practices and prevents potential conflicts.
- Select your project in the Project navigator.
- Choose your target.
- Navigate to the “Build Phases” tab.
- Expand the “Copy Bundle Resources” phase.
- Select the Info.plist file.
- Click the minus (-) button to remove it.
Best Practices for Managing Info.plist
Beyond simply removing the file from the “Copy Bundle Resources” phase, understanding best practices for managing your Info.plist file is essential. Avoid manually editing the file directly unless absolutely necessary. Instead, leverage Xcode’s built-in capabilities to modify settings like app version or supported orientations through the project editor. This minimizes the risk of introducing errors and ensures consistency.
Consider using configuration files (xcconfig) to manage build settings and environment variables across different build configurations (debug, release, etc.). This helps streamline the build process and reduces the chance of inconsistencies across different environments. Furthermore, thoroughly document any custom modifications made to the Info.plist file to ensure maintainability and facilitate collaboration among team members.
Preventing Future Issues
Regularly reviewing your project’s build phases and ensuring the Info.plist file isn’t inadvertently added back to the “Copy Bundle Resources” section is a good preventative measure. Incorporating automated build checks or linters can help catch such issues early in the development cycle. Staying updated with the latest Xcode releases and best practices further minimizes the risk of encountering this or similar build warnings.
- Regularly review build phases.
- Utilize automated build checks.

Question & Answer :
I’ve separated a project into two builds and given each of them a plist file. Everything works fine, but I keep getting this build warning:
Warning: The Copy Bundle Resources build phase contains this target’s Info.plist file ‘MyApp-Info.plist’
I get this when I try to build MyApp. Building for the second target gives the same error (with SecondTarget-Info.plist in the warning). I’m not sure why it’s a warning, since I want the build to contain that .plist file. Each of the .plist files have one target membership (for their own build).
What does this warning mean? Is there any way to make it go away?

Excerpt:
You are getting this warning because you probably added your Info.plist file to your Copy Bundle Resources build phase as shown in Figure
The INFOPLIST_FILE build setting specifies the name of the Info.plist associated with your target. When building a target, Xcode reads this build setting and copies the referenced Info.plist into your application bundle. Because Xcode automatically processes the Info.plist, you should not add it to your Copy Bundle Resources build phase or make it a target member.
To resolve this warning, select your Info.plist from the Copy Bundle Resource build phase as shown in Figure 1, then click the Remove (–) button to delete it from the phase.
