Xcode High Sierra Install Xcode 10

Apparently, open all your code inside 8 and let it update everything. 2) You cannot go from Xcode 7 directly to 10.2.1 or 10.3 doesnt matter if you have existing code or not, you must install Xcode 10.1 first, let it load all the supporting files. 3) Follow the instructions EXACTLY as Chris has written them to upgrade from 10.1 to 10.2.1. Skip a step and it wont work.

This is not in anyway supported by Apple as they have specifically set the new version of Xcode 10.2.1 for the latest OS only.

We found that these steps work for us and we cannot guarantee if it will work for you.

And your done you can now use xcode 10.2.1 in your your Mac You will notice that the error icon is gone and you can now launch and use xcode10.2.1 for app development (Now working) Xcode 10.2.1 Share Tweet Pin Share Buffer Have you teamed up with a partner to develop an app Make sure your shared codebase is always building and get notified of errors as soon as they happen.

Comments Scott December 2, 2019 at 6:26 pm Thank you so much I am a Mac newbie, so this was a bit intimidating, but I wanted to share that not only does following these instructions verbatim work fine on High Sierra for me, but it worked to the latest Xcode of 10.3.

The only thing I must point out that the instructions omitted (assumed we would know) is how to edit the Info.plist files.

Presumably this is the second reason we needed to have 10.1 installed first, I learned you need to use Xcode to edit the Info.plist files.

No save button, just edit the value and quit out.

Rebooted. When I ran the 10.3 app it complained it needed to download more updates, which scared me, but it did this and then Xcode 10.3 opened up without any complaints Didnt try to use it yet, assume it works.

Thank you Reply Harie Venad November 23, 2019 at 6:43 am Thanks you saved my time and money.

Reply rick October 24, 2019 at 4:01 am hi what are.xim files and are they different to.xip files Reply Aabbcc November 23, 2019 at 12:28 pm No, it seems to be a mistake.

The file extension is.xip, its right in the screenshot Reply SARAH October 21, 2019 at 5:57 pm HOW DID YOU EVEN EDIT THE INFO.PLIST LIKE ITS ALL MESSED UP WHEN OPENED WITH TEXT EDIT PEOPLE Reply Aabbcc November 23, 2019 at 12:28 pm You open it with your previous Xcode version Reply Princess Dawn Milly Mills November 25, 2019 at 10:03 pm See answer originally posted Dec 24 2010 Reply pps November 29, 2019 at 10:15 pm I not leaving my name and I might be late but I recommend using the existing Xcode 10.1 for editing the plist file.

Also, check out dosdude1 patcher, check the all tabs before downloading as I know my Mac and its use case wouldnt run without full graphics acceleration.

Reply unix November 1, 2019 at 11:16 pm This disables SIP (System Integrity Protection), is only to be done when its really necessary (modifying Library things does not count) and could expose your Mac to dangers.

Reply Bob October 12, 2019 at 8:22 pm I had to rename the Xcode Application name once more to remove the cannot run image.

Xcode High Sierra Simulator Is Working

This made the trick Reply paul September 29, 2019 at 9:38 pm the simulator is working too now.

Have to do the same for simulator info.plist.

ApplicationsXcode1021.appContentsDeveloperApplicationsSimulator.appContentsinfo.plist).

Reply paul September 29, 2019 at 7:41 am Hi, Thanks for putting this up.

Does anyone experiencing with the simulator greyed out Please let me know if you have an idea on how to get it to work.

Steve Reply vike September 10, 2019 at 8:28 pm As some seem to fail Ill share my success: Using hardware: iMac (21.5-inch, Mid 2010), 3.06 GHz.

GB. I only worked off of an Xcode10.2.1.xip from developer.apple.com.

Unpacked by open -a Archive Utility.

Edited like cp -pi ApplicationsXcode10.1,10.2.appContentsDeveloperusrbinxcodebuildfor bundle in ApplicationsXcode10.2.app,ContentsDeveloperApplicationsSimulator.app;do defaults write bundleContentsInfo LSMinimumSystemVersion -string 10.13.6;done.

No restart needed.

Admin access needed first run (to complete install).

Finally Ill add my local date, afaics otherwise wholly lacking on this page: September 2019.

Reply Chunga September 28, 2019 at 3:44 pm Thanks a lot Xcode 10.3 worked like a charm on iMac mid 2011 running High Sierra Reply JLMcB September 9, 2019 at 10:40 pm Like Jurie, I was also able to get this working for 10.3 on High Sierra.

Note: For some reason the plist files were cached before I edited them, so after editing and rebooting I was still blocked.

So, I had to force a re-cache of the plist files (there are multiple ways to do this) to be able to start xcode 10.3.

Reply Bruno August 28, 2019 at 8:22 am Thanks man I had been searching this solution many daysits saved me Reply Mike LeGault August 26, 2019 at 8:04 pm Hi, So Ive posted a couple times with issues I was having.

Machine:Macbook Pro 13 mid 2010 running OS 10.13.6, Xcode 7.

OS 10.13.6 is max for this machine Apple wont let it go any further.

Xcode stopped updating a long time ago I dont know why.

If you have Xcode prior to 8 and you want to keep your program code you must install Xcode 8 to bring your code up to date.

Apparently, open all your code inside 8 and let it update everything.

You cannot go from Xcode 7 directly to 10.2.1 or 10.3 doesnt matter if you have existing code or not, you must install Xcode 10.1 first, let it load all the supporting files.

Follow the instructions EXACTLY as Chris has written them to upgrade from 10.1 to 10.2.1.

Skip a step and it wont work.
