Xcode Simulator how to remove older unneeded devices

Question

I m running Xcode 4 3 1 iOS-Simulator which originally only supports iOS 5 1   I need to test my code with iOS 4 3  so I used Xcode s  Install  feature to install it as described in  Installing Xcode with iOS 4 3 device simulator    Now I m finished with testing but cannot find a way to uninstall the 4 3 portions   iPhone 4 3 Simulator  and  iPad 4 3 Simulator    I want to reduce the clutter in the Scheme menu   No one on Apple s Xcode listserv knew the answer   EDIT  note that much has changed since Xcode 4 3  so suggest anyone reading this look at all the answers  The newest ones such as Steve Moser s may be of more use to you   EDIT 10 2017  Posted on Twitter by Julio Carrettoni       If you are an iOS developer  execute this      xcrun simctl delete unavailable   It removes old simulators Xcode no longer use  For me it was 6Gb   Did not try it myself       Also  I just saw Russ Bishop mentioned this in a comment below already

Xcode 4 6 will prompt you to reinstall any older versions of the iOS Simulator if you just delete the SDK  To avoid that  you must also delete the Xcode cache  Then you won t be forced to reinstall the older SDK on launch   To remove the iOS 5 0 simulator  delete these and then restart Xcode     Applications Xcode app Contents Developer Platforms iPhoneSimulator platform Developer SDKs PhoneSimulator5 0 sdk   Library Caches com apple dt Xcode   For example  after doing a clean install of Xcode  I installed the iOS 5 0 simulator from Xcode preferences  Later  I decided that 5 1 was enough but couldn t remove the 5 0 version  Xcode kept forcing me to reinstall it on launch  After removing both the cache file and the SDK  it no longer asked

I wrote up one-line bash script that would delete ALL your simulators   xcrun simctl list devices   grep -E -o -i    0-9a-f  8 -  0-9a-f  4 -  3  0-9a-f  12      xargs -L1 xcrun simctl delete    xcrun simctl list devices will list all the simulators installed on your machine grep -E -o -i    0-9a-f  8 -  0-9a-f  4 -  3  0-9a-f  12    will grab the device UUID xargs -L1 xcrun simctl delete will attempt to delete the device for each UUID it found   If you want to see everything it ll execute  you can add echo before xcrun  i e   xcrun simctl list devices   grep -E -o -i    0-9a-f  8 -  0-9a-f  4 -  3  0-9a-f  12      xargs -L1 echo xcrun simctl delete

I had the same problem   I was running out of space  Deleting old device simulators did NOT help  My space issue was caused by xCode   It kept a copy of every iOS version on my macOS since I had installed xCode  Delete the iOS version you don t want and free up disk space   I saved 50GB  of space     NOTE - gt  can t you see   Library inside Finder   It is hidden by default   Use Terminal and type cd   Library Developer Xcode iOS  DeviceSupport  or google how to see hidden folders    NOTE - gt  if you have multiple users on a single macOS machine  make sure to find the directory ONLY with the user account that originally installed xCode

The problem with these answers is that  with every Xcode update  menus and locations will change    Just go to  Applications Xcode app Contents Developer Platforms and delete what you don t need  Xcode will start fine  If you re at all concerned then you can simply restore from Trash

In addition to  childno de answer  your Mac directory       private var db receipts     may still contains obsolete iPhoneSimulatorSDK  bom and  plist files like this       private var db receipts com apple pkg iPhoneSimulatorSDK8 4 bom    private var db receipts com apple pkg iPhoneSimulatorSDK8 4 plist   These could make your Downloads tab of Xcode s preferences show a tick  v  for that obsolete simulator version   To purge the unwanted simulators  you can do a search using this bash command from your Mac terminal      sudo find   -name   PhoneSimulator     Then go to corresponding directories to manually delete unwanted SimulatorSDKs

Some people try to fix it using one way  some the second  Basically  there are 2 issues  which if you check them out  amp  solve both - in 99  it should fix this issue    Old device simulators located at YOUR MAC NAME  e g  Macintosh  -  Users -  YOUR USERNAME  daniel  -  Library -  Developer -  Xcode -  iOS Device Support  Leave there  the newest one  as of today this is 13 2 3  17B111   but in future it ll change  The highest number  here 13 2 3  of the iOS version indicates that it s newer  After this list your devices in Terminal by running xcrun simctl list devices  Many of them might be unavailable  therefore delete them by running xcrun simctl delete unavailable  It ll free some space as well  To be sure that everything is fine check it again by running xcrun simctl list devices  You should see devices only from the newest version  here 13 2 3  like the screenshot below shows      As a bonus which is slightly less relevant to this question  but still free s some space  Go to YOUR MAC NAME  e g  Macintosh  -  Users -  YOUR USERNAME  e g  daniel  -  Library -  Developer -  Xcode -  Archives  You ll see many archived deployed application  most probably you don t need all of them  Try to delete these ones  which are not being used anymore   Using these 2 methods and the bonus method I was able to get extra 15 GB of space on my Mac   PS  Simply deleting simulators from Xcode by going to Xcode -  Window -  Devices and Simulators -  Simulators  or simply CMD   SHIFT   2 when using keyboard shortcut  and deleting it there won t help  You really need to go for the described steps

I tried all answers  None of them worked for me    What worked for me on Sierra   Xcode 8 2 was going to    Library Developer CoreSimulator Devices and deleting all devices     Maybe this won t work for you  maybe this is a solution as a standalone  or maybe you have to do this in addition to other answers  but I did all solutions here and so not sure what did the deed   Just be aware that some of the answers here are old and the location of simulator has changed  Snowcrash s answer seems to be most recent
