Using UAT 1.3.1

Pffff... wondering if next iOS updates will continue to break existing apps or...

[radek_ne]

It does not look too good This may be temporary problems. The same SDK 5.1 still has bugs. So it was with 5.0.

[giggsy]

The good thing is, it only happens when reopening the app a few times, so for our case it's not thaaaat crucial

Can you build and install your game on your device. I upgraded to iOs 5.1 and get an clang error...
How did you work around this!?

Kind regards,

Markus

I'll ask our human build server tomorrow ... PM me or bump this thread in case I forget

I upgraded so i could use iOS 5.1, but now my compiler has the following error: ...
Do I need a new UAT?? How did you get it to work on the device?
What to do? Did you get this error?

For us it works this way:
- We upgraded the iOS SDK + xCode and the device (4s) to iOS 5.1.
- We use UAT 1.3.1.
- Don't forget to clean your solution
- Our project has some non "out of the box" settings, but can't tell which they are and if they are relevant.

The only thing that occurs is the multiple open -> resume bug.

Set Optimization Level to O1. Higher Optimization Level crashes clang.

I tried several things in the compiler settings. I have it working now for the iPhone, but the same settings lead to unresponsive game on the iPad...

I am going to wait until the new UAT. Several things seem to be broken. Should have waited with the upgrade

I've posted the problem in the official Apple Dev forums:

I had the same issue with clang crashing when using updated iOS/Xcode, but your suggestion solved my problem. Thanks for the tip!
