Developing an Ionic iOS application on macOS Sonoma 14.4.1 with Xcode 15.3 may lead to a sandbox error that hinders the build process.Xcode's User Script Sandboxing restricts file system access of build scripts, causing issues with legitimate operations involving CocoaPods.Common failed solutions include cleaning the build folder, running CocoaPods commands, and upgrading CocoaPods.To resolve the sandbox issue, developers need to disable User Script Sandboxing for both the target and project settings in Xcode.
