In order to test something for another AppGameKit user, I allowed my iPad to update to iOS 6.

Then it was not recognized by Xcode 4.

Then I got offered the Xcode update and installed it. It took an hour for it to download. After installation, it no longer allowed the selection of iOS 5.1 SDK. And a built app will not run on my iOS 5.1 device.

I finally discovered how to be able to build and test for both, at least in theory.

Use Xcode->Preferences->Downloads to add the iOS 5.1 Simulator. This lets you use the iPad/iPhone simulators for both iOS 5.1 and iOS 6. You can install other simulators as well.

It also let me build/install for my iOS 5.1 iPod Touch. To build/run for iOS 5.1, set the iOS Deployment Target to 5.1 in the Info panel for the project (not the target info panel).

However, I'm having difficulty getting my previously working app to install on my iOS 6 iPad. Further testing/investigation needed.

I got it!

Make these changes for both the PROJECT and TARGETS -

Set Build Settings->Architectures->Base SDK to 'Latest iOS(x)' in ('x' is now 6.0 on mine).

Set Build Settings->Architectures->Valid Architectures to only 'armv7'. (It was allowing armv6 that was messing up my iPad iOS 6).

Set Build Settings->Deployment->iOS Deployment Target to 'iOS 5.1' (we probably can assume that everyone has updated to that, if you prefer not to, use one of the other values).

Oh yes i knew this thing cause it happened to me the last time ehehe...
Anyway i also re install all the old simulators too.

I must also test if the simulator now didn't fire all that errors on frameworks.

Long life to Steve!

Hmmm well, i'm testing it now, but as i see Apple need 4.3 minimum.
When you archive the code and send it to apple it will be rejected i think.
I got this error while updating the CB Radio Box app and i did the 4.3 options as they asked.

Long life to Steve!

I know that you can use iOS 4.3 as a target and it builds properly and installs via Xcode 4 on iOS 5.1 devices.

I just tested using iOS 4.3 as a deployment target on my iOS 6 device and it worked fine.

Quote: "can you also build for ios 4.x ?"

So, the answer is 'Yes'.

i am planing to update to mountain lion and the latest xcode as soon as i finish the project i am working on.

most games don't use any specific 5.x or 6.x features so making them only 5.x up restricts how many people can play your game

Building something for 4.3 still works on an iOS 6.0 device. So we can program to the lower end, nice.

Any time Apple comes out with a new major iOS release, they also come out with Xcode updates. Fortunately, it turns out that the Xcode updates are backwards compatible.

I haven't upgraded my core Mac OS, yet. But I might.

Hi all,

IPad updated to version 6.0 and installed XCode 4.5 and now I can not run anything. Help solve the problem.

XCode 4.4.1 the same code compiles and runs in Simulator 5.1

First, when you say you cannot run anything, are you referring only to apps you built with AppGameKit?

Next, what happens when you try to run stuff?

Did you try the various things discussed in this thread?

Yes

XCode 4.4.1 the same code compiles, but runs in Simulator 5.1 now. XCode 4.5 - not compile.

What errors are you getting?

Do you see both iPhone/iPad 5.1 and 6.0 simulators in the template selection drop down at the top/left of Xcode?

After you updated your Xcode, did you clean your project and rebuild it?

Or did you just tell it to run?

What version of the Apple OS are you running?

Have you updated your core Apple OS? (I haven't and won't for a while, so I'm not suggesting that you do.)

Compilation stops on different files.

Make sure that all your .cpp/.c files are set to compile as 'File Type' = 'Objective-C++ Source'. This is set in the column on the right.

It is not impossible that this might fix the issue. But it might not. It is a way to avoid some other issues that some times pop up.

Quote: "Compilation stops on different files."

Do mean the compiling the same project fails in different files at different times when there has been no changes in the files?

If so, this indicates an issue not necessarily having to do with your project.

Have you tried cleaning and then compiling in Release mode?

And, while one wouldn't normally do this with anything but a Windows machine, have you tried shutting down all applications, closing down your Mac and restarting it? I actually had to do that after the updates to let everything 'settle'.

Found a solution: XCode 4.4.1 compiles all the encoding *.cpp files, but XCode 4.5 only UT8. If the *.cpp file actually ANSI, then 4.5 defines it as UT8 and not compiles it! Need an external editor to rewrite it in UT8
