In my tests, the failure to successfully install watchOS symbols broke down in step 7, where the package is supposed to successfully copy symbol files into my home folder. A macOS Installer package on the disk image is used to install symbol files directly into your home folder.The disk image is mounted at a temporary location on your Mac.The disk image file is copied to a Caches subfolder in your home directory.A disk image file containing the required materials is downloaded to a temporary folder.If symbols are not already installed, the symbol-installation process begins.Xcode looks for existing symbols in the suitable home directory location.A device suitable for development is connected.Symbol Installation Overviewįirst I want to give you a high level idea of how Xcode downloads and installs symbols. I’ll give an overview of how Xcode’s symbol installation process works, and walk you through one concrete method for working around the problem, getting those precious symbols installed, and breaking the cycle of perpetual failed installations. I’ve been to hell and back tracking down exactly how Xcode installs these symbols, where it fails, and how to work around the problem. This is no big deal on my home network, but when I’m roaming and tethered to my bandwidth-metered iPhone, it can lead to costly overage charges. The worst side-effect of this bug for me, and the problem that finally encouraged me to hunker down and solve the issue, is the fact that each attempt to “Install Symbols” is associated with a fresh download of a larger-than-200MB file from Apple to my Mac. However, for those of you who are actually doing Watch development, if you run into this problem, you’ll be perpetually greeted by this error when you try to debug on a real device: The bug doesn’t seem to affect the performance of my Mac, and other actions I perform in Xcode continue without delay. If I open Xcode, and my iPhone (paired with an Apple Watch) is attached to the Mac, I am greeted by a progress indicator such as this:īecause I don’t actually do any watchOS development, this has mostly been a mild annoyance. MacOS 10.For months I have been plagued by Xcode’s persistent failure to successfully install WatchOS device support on my Mac. Fixed a bug that could cause items not to extract correctly from Mac OS 9 Installation Tome archives.Fixed a bug that could cause excess memory usage in some cases.Added a Spanish localization by Óscar Hérnandez.Finally, Pacifist can examine the kernel extensions installed in your system to let you see what installer installed them, and whether the installer was made by Apple or a third-party. zip archive without waiting for the entire archive to download. Pacifist can also load some archive types over HTTP, in case you want to extract just a single file from a large. This is useful if you need to install just one file out of a package instead of the entire package (for example, if you deleted your Preview application and need to reinstall it, but not the whole operating system), or if you want to inspect a downloaded package to see what it will do before installing it. ![]() ![]() xar archives and more, and lets you extract or install individual files out of them.
