## Discussion

Discussion Use the fileProviderErrorForCollision(with:) method to create properly formatted filenameCollision errors. You have two options for resolving file name collisions: Your file provider extension can return this error. In this case the system renames the new item. You can rename the new item yourself. This gives you complete control over the process.
