Recommended Xcode versions

For the most up to date information on Xcode, go here.

General rule - you should always use latest minor (.x) release of Unity.

Unity 3.4.x - was tested with Xcode 3.2.6 and Xcode 4.2. Unity 3.4.x won't receive any updates.
Unity 3.5.x - should work fine with Xcode 4.2 / 4.3 / 4.4 / 4.5 / 4.5.2 / 4.6 / 5.0 (except Build&Run). We strongly recommend upgrading to Unity 3.5.7.
Unity 4.5.x - should work fine with Xcode 5.0. Xcode 5.1
Unity 4.5.4p1 - adds support for Xcode 6 and iPhone6/6+. Build can be downloaded at (http://forum.unity3d.com/threads/unity-patch-releases.246198/#post-1778651)
Unity 5.3.x - Xcode 7.2 / 7.3 / 8.0
Unity 5.4.x - Xcode 7.2 / 7.3 / 8.0
Unity 5.5.x - Xcode 7.3 / 8.3 / 9.0
Unity 5.6.x - Xcode 7.3 / 8.3 / 9.0
Unity 2017.x - Xcode 7.3 / 8.3 / 9.0

 

Nice thanks for that list, I was wondering if it was safe for me to update xcode.

It would be really useful if the release note contained the version of xcode that the release was tested on.

 

These kind of 'don't update' posts need a seperate forum section and to be stickied.

 

I agree

 

Hello Mantas,

This basic license issue with Xcode 4.5 is a technical or legal problem? Can you give any additional details?

Thanks

 

It's a technical problem. Unity runtime will falsely detect standard splashscreen modification. You can work around it by setting Xcode project option "Compress PNG files" to "NO".

 

Thanks! Just to confirm, this problem doesn't happens when using the Pro license?

 

Pro should work fine.

 

So, its safe to run all versions of Unity Pro with Xcode 4.5?

 

.
It is safe to use Unity 3.5.5 with iOS Pro with Xcode 4.5. Older versions might not work (like might need to change compiler version to LLVM GCC).

 

I hope to don't be offtopic, but with XCode4.5 I've weird orientation issues when the application requires to work on landscape mode.
Anyone else is experiment the same issue?
Any quick-fix for that?

 

I'm also having this problem. The application wont actually build through xcode as it complains about an error relating to the "ConvertToUnityScreenOrientation" method.

 

After upgrading to xcode 4.5 with unity 3.5, all my GUI.Button have disappeared ! Any clue ?

 

Why wasn't this thread locked? It should be for information only, and not a free for all.

 

There's some useful information being discussed, so no thanks.

 

I agree too.

 

Hi Everyone,
Unity 3.5.6f4 was just released. It fixes most of the known problems with Xcode 4.5 / iOS 6.0 / iPhone 5. Of course it also adds iPhone 5 resolution support. First post was updated accordingly.

 

Unity 4 hasn't been updated though, right?

 

Do I have to install Xcode 4.5 to use Unity 3.5.6 just for native iPhone 5 support? (I don't need any other iOS 6 features). Will Xcode 4.3 be enough for that? thanks.

 

iOS6 requires XCode 4.5 or at least 4.4 + http://www.jonathanhogervorst.com/p...6-device-for-testing-with-xcode-4-4-and-ios-5
but then you can no longer send in your applications. building against iOS6 sdk for store is only possible with xcode 4.5

 

My game use armv6 build to xcode 4.4 can be normal use iphone to test, but joined the armv7 after that, only a small number of model can see, and other models are black, I want to know that this should be how to solve?
...unity 3.56

 

I'm sorry, but I did not understand one bit of what you tried to say. What problem exactly are you having?

 

Is there a problem with Unity4 basic + iOS basic + XCode4.5.2 = Splash Screen Error?
Setting png to not compress in XCode did not help.

 

Solution: Delete App from iPad (compiled with old Unity). Install newly compiled App.

 

This does not work..at least for me. I've tried all variations.

Is there a solution for this?

 

This is what I did additionally:
1) Use newest Version of Xcode
2) Clear cash in Xcode
3) Delete Unity project output folder

 

Hi Rolf,
I'm on XCode 4.5.2, and I deleted the original project output.
By cash (cache?) do you mean Clean Project?

Edit: Success! That seems to work doing a clean project. Thanks Rolf!

 

Hi I am currently using Unity 3.5.6f4 as you recommended but when i build for iOS (Xcode 4.3), it creates the Xcode project but then when i try to build for Device i get this error. and i never used to get this before and cannot find anything about this error anywhere.

/Users/standardaccount/Desktop/Project Urenco/Urenco/Build/iOS/Richie1.3.8/Libraries/Assembly-CSharp.dll.s:unknown:FATAL:Section too large, can't encode r_address (0x1031118) into 24-bits of scattered relocation entry
clang: error: assembler command failed with exit code 1 (use -v to see invocation)
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

Can someone please help me out i have been on forums and google for 3 days and haven't found a solution for this.

Thanks
Abz

 

You are hitting Xcode linker bug, which typically is hit when too much code is being linked as single module. You might try updating Xcode to newer one or split your script code into multiple .NET assemblies. One of easy ways to split code into multiple assemblies - move some to Plugins folder.

 

I'm using Unity 4.0.0f7 and using Xcode 4.5.2 and am getting the following 3 errors when I try to build in Xcode:

These are all contained in the "AppController.mm" file

1. "No member named 'w' in 'EAGLSurfaceDesc'
2. Use of undeclared identifier '_curOrientation'; did you mean 'orientation'?
3. Cannot initialize a parameter of type 'int' with an lvalue of type 'NSString *'

Any thoughts?

 

Most likely you are using 3rd party native plugin, which is not compatible with Unity 4.0.

 

Thanks! Turns out I was using an older version of Vuforia

 

I'm suddenly having a problem with not being able to script debug (posted as a question here: http://forum.unity3d.com/threads/16...land-when-trying-to-activate-Script-Debugging)

The error is "Unable to insert branch island"

I'm using:

* Mountain Lion 10.8.2
* XCode 4.5.2
* Unity 4.0.0f7
* Scaleform IOS
* Vuforia 2.0
* Run target: iPhone 5 IOS 6.0.2

I've tried:

* Fiddling with OS settings
* Rebuilding to a completely blank project
* Reinstalling XCode
* Re provisioning the iPhone

 

I've just upgraded to Xcode 4.6 with the iOS 6.1 SDK and it seems to be fine with Unity 4.0.1f2 (w/ non-Pro iOS license).

 

Has anyone used Xcode 4.6 specifically with Unity 4.0.0f7? I made the mistake of upgrading my iOS to 6.1 which requires Xcode 4.6, but am in the middle of a unity project and don't want to upgrade unity.

 

thanks for your update..

 

Does Unity 3.5.7f6 work with Xcode 4.6 and iOS 6.1?

--Roy

 

I'm waiting for the first post to be updated with this info too.

 

updated

 

I just updated to XCode 4.6 (which is required if you updated your iOS device to 6.1) and it works great with iOS 6.1 with a Unity v3.5.6f4 build.

 

Hi, I need to upgrade XCode to 4.6 in order to deploy to my iOS6 iPhone, but I understand XCode 4.6 requires Lion.
Lion is no longer available and Mountain Lion system requirements is beyond my machine! (I'm on a late 2006 MBP)
Does anyone know if I have any options here? (Beside buying a new mac, which I can't afford)

 

I believe you can still purchase Lion directly from Apple by calling them.

 

I did just that and I've purchased Lion. I got round the fact that my phone tech support has expired by telling them I'm a paid member of the iOS Development Program. I believe I'll make a Dual Boot Snow Leopard/Lion system at least to start, just in case Lion breaks anything important.

Thank you very much JJC1138! Sterling advice!

 

I second that. This kind of information is critical to most developers.

 

Hi,

I see xcode has been updated to 4.6.1 on the 14th March, anyone tried it yet?

What are the dangers of upgrading? Is it easy to roll back?

I need to update from xcode 4.5.2 as I need to support 6.1. I guess I could find xcode 4.6.0 and install that, but it would be much easier to just let OSX update straight to 4.6.1.

 

On 4.6.1 at the moment and there appears to be no problems for me.

 

Thanks for replying, i'll update xcode a bit later.

Wish the forum had a simple thanks button though, so I didn't have to waste space with an actual reply.

 

We have had serious problems after upgrading to Unity 4.1 and Xcode 4.6.1. We get crashes on iPads that are intermittent and occurring in varied places. Also, after working most of the night to track down the problem, this morning Unity 4.6.1 would crash on startup reading the project that was fine last night.

We are currently going back to 4.0.1 and Xcode 4.5.2. :-(

 

Can someone please explain the issues we'll have with using Unity 3.5.7 once iOS 7 and Xcode 5 are released? Will there be another 3.5 release to cover iOS 7?

Thank you.

 

"We strongly recommend upgrading to Unity 3.5.7" Can upgrade to just 3.5.7? From what I can see my license is only an upgrade to 4.0 ... which will cost me $2400 US.
I currently have an older version of unity ios 1.7
Is it possible to upgrade at a lesser cost to 3.5.7?

Thanks
