Xcode is Apple's integrated development environment for macOS. A .pbxbtree file contains internal data used by Xcode's auto-complete feature, rather than source code intended for direct editing.
The file is generated and maintained by Xcode as part of its project support data. It is normally used only on the Mac where Xcode is installed and can generally be recreated by Xcode if it is removed. The format is not intended for exchange or manual conversion.
Open a .pbxbtree file with Apple Xcode on macOS. It is an internal support file, so Xcode normally opens and manages it as needed rather than displaying it as a standalone document.
A .pbxbtree file does not have a useful standalone conversion format. If the file is needed by a project, allow Xcode to recreate it instead of converting it manually.
