XCode 5 app crashes in 10.7

Woggledog · October 22, 2013, 10:22am

This app does nothing. And I mean: NOTHING

Created a new project in XCode 5.0. Changed the size of the window, removed resize, close options, etc

Deployment target is 10.7

copy the app over to my 10.7 VM and I get:

22/10/2013 11:06:28.579 talagent: kCGErrorIllegalArgument: CGSBindSurface: Invalid window 0x22

This, incidentally, is what I get for an existing app that, prior to XCode 5, was working just fine.

Any ideas?

What OS are you building it on? Are you using ARC or garbage collection?

Woggledog · October 23, 2013, 8:48am

XCode 5.0
Mac OS 10.8.4

Just to check my sanity, I’ve gone to file > new > project

changed the deployment target to 10.7

built the project : it whines:

copy the resulting app over to 10.7.5 VM

run

it crashes and I get:

With regards to your last question:

Apple LLVM 5.0 - Language - Objective C
Setting
Objective C Automatic Reference Counting Yes Yes Yes No (for OS X default)

Shane_Stanley · October 23, 2013, 10:38am

You can’t use ARC for ASObjC apps you want to run under anything earlier than 10.8 – you have to use garbage collection.

StefanK · October 23, 2013, 10:46am

I’d like to add:

the first whining error message indicates, that Base Localization “ a comfortable new feature to localize apps in cooperation with Autolayout - is not available in Lion

Woggledog · October 23, 2013, 11:03am

But you have to use ARC for 10.9, correct?

Shane_Stanley · October 23, 2013, 11:05am

No. You may have to use ARC to use some of the (unspecified) new-to-Mavericks APIs – but that would mean a 10.9-only app anyway.

Woggledog · October 23, 2013, 11:10am

However, I could have a conditional build setting, that, theoretically uses Garbage Collection for 10.7 and ARC for 10.8+ ?

Shane_Stanley · October 23, 2013, 12:16pm

No. There are theoretical methods using fat binaries, one version 32-bit, and some Info.plist fiddling, but I’ve never tried it.

How do I switch an existing project? I just wrote mine with the default settings and it won’t run on 10.7; I expect for the reasons you mentioned.

I went into Project → basic. Under Apple LLVM 5.1 Language Object C. I changed Objective-C Automatic Reference Counting from Yes to No.

Something else I need to do?

Shane_Stanley · June 26, 2014, 11:59pm

Yes, there are several other steps. You need to use Xcode 5.0.2 or earlier. You also need to change the deployment version, and add a new manual build setting to enable garbage collection. And you have to make sure the build settings for the .xibs is correct, Base Localization is off, and Auto Layout is off.

Shameless plug: there’s a full checklist in the the latest edition of my book.
