Projects that are alternatives of or similar to Xcode Defaults
Xcode defaults
Backup Xcode defaults
defaults read com.apple.dt.Xcode > ~/Desktop/XcodeDefaults.plist
Restore Xcode vanilla defaults
If you delete/move the current plist, Xcode will write a fresh one next time you run it.
killall Xcode
mv ~/Library/Preferences/com.apple.dt.Xcode.plist ~/Desktop/XcodeDefaults.plist
open -b com.apple.dt.Xcode
Enable project build time
defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES
Enable parallel builds for Swift
defaults write com.apple.dt.Xcode BuildSystemScheduleInherentlyParallelCommandsExclusively -bool YES
Disable parallel builds for Swift
Xcode 9.3 now runs more Swift build tasks in parallel with other commands. This may improve build times for Swift projects, but may also increase memory use during the build. This feature can be disabled from Terminal by setting a user default with
defaults write com.apple.dt.Xcode BuildSystemScheduleInherentlyParallelCommandsSerially -bool YES
Enable multi-cursor editing
defaults write com.apple.dt.Xcode PegasusMultipleCursorsEnabled -bool YES
Enable maximum number of concurrent compile tasks
defaults write com.apple.dt.Xcode IDEBuildOperationMaxNumberOfConcurrentCompileTasks `sysctl -n hw.ncpu`
Enable/Disable indexing
Enable indexing
defaults delete com.apple.dt.Xcode IDEIndexDisable
defaults write com.apple.dt.Xcode IDEIndexEnable -bool YES
Disable indexing
defaults delete com.apple.dt.Xcode IDEIndexEnable
defaults write com.apple.dt.Xcode IDEIndexDisable -bool YES
Show Indexing numeric progress
defaults write com.apple.dt.Xcode IDEIndexerActivityShowNumericProgress -bool YES
Show Indexing logging
This will show you why a particular file is having trouble being compiled for indexing.
defaults write com.apple.dt.Xcode IDEIndexShowLog -bool YES
Show prebuild step logs
defaults write com.apple.dt.Xcode IDEShowPrebuildLogs -bool YES
Set SourceKit log level
If set to SourceKit will write a log to /tmp with all the details of what it is doing while indexing. A lot of people find they have header hygiene problems or module problems that happen to work while building in certain configurations but aren't actually correct, resulting in missing modules or broken headers from the indexer's point of view. May not work anymore.
defaults write com.apple.dt.Xcode IDESourceKitServiceLogLevel -int 3
Disable Main Thread Checker
Deactivates the Main Thread Checker. Found in Xcode 12 release notes
defaults write com.apple.dt.Xcode DVTDisableMainThreadChecker 1
Enable internal Xcode (debug) menu
defaults write com.apple.dt.Xcode ShowDVTDebugMenu -bool YES
Disable automatic reopening of last project
Prevents Xcode from automatically restoring the last open project. This enables running multiple Xcode versions for different projects.
defaults write com.apple.dt.Xcode ApplePersistenceIgnoreState -bool YES
Some minimal additional logging
defaults write com.apple.dt.XCBuild EnableDebugActivityLogs -bool YES
Enable build debugging mode
This slows down the build system & litters DerivedData//Build/Intermediates.noindex), generally should only be enabled when trying to capture a trace for incremental build debugging purposes.
defaults write com.apple.dt.XCBuild EnableBuildDebugging -bool YES
Make Assistant aware of more companion files
Make Xcode's Assistant aware of your ViewModels, Views, etc. Found by @peterfriese
defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View" "Screen"
Disable move files on restructure
Do not move files when you restructure things in an Xcode project. Found by @steinpete
defaults write com.apple.dt.Xcode IDEDisableStructureEditingCoordinator -bool YES
Disable state restoration
Stop Xcode from reopening files on launch. Found by @SmileyKeith
defaults write com.apple.dt.Xcode IDEDisableStateRestoration -bool YES
📱 Simulator
Enable Simulator fullscreen mode
defaults write com.apple.iphonesimulator AllowFullscreenMode -bool YES
🏗️ XCBuild
Enable Build Debugging
Creates an XCBuildData folder in ~/Library/Developer/Xcode/DerivedData/<your target>/Build/Intermediates.noindex/
which contains debugging info for xcodebuild.
defaults write com.apple.dt.XCBuild -bool YES
🗑️ Xcode Cleanups
Remove all Xcode DerivedData
... provided Xcode is set to default folder locations. This is a quick win and helps to get back gigabytes of storage space. Do this regularly.
rm -rdf ~/Library/Developer/Xcode/DerivedData/*
Remove all Xcode DeveloperTools cache files
... provided Xcode is set to default folder locations.
CACHE=$(getconf DARWIN_USER_CACHE_DIR)
rm -rdf ${CACHE}com.apple.DeveloperTools
rm -rdf ${CACHE}org.llvm.clang.$(whoami)/ModuleCache
rm -rdf ${CACHE}org.llvm.clang/ModuleCache
rm -rdf ~/Library/Caches/com.apple.dt.*/*
Remove all Xcode / Swift temporary files.
TMP=$(getconf DARWIN_USER_TEMP_DIR)
rm -rdf ${TMP}*.swift
rm -rdf ${TMP}ibtool*
rm -rdf ${TMP}*IBTOOLD*
rm -rdf ${TMP}supplementaryOutputs-*
rm -rdf ${TMP}xcrun_db
rm -rdf ${TMP}sources-*
rm -rdf ${TMP}com.apple.dt.*
rm -rdf ${TMP}com.apple.test.*
