    PowerVR SDK 3.5 using XCode 7, targeting iOS 6.1 (and others).

    The sample(s) build, but on execution the following happens:

    InitApplication() succeeded
    InitView() succeeded
    2015-09-11 18:59:27.340 OGLES2Water[1863:58149] *** Assertion failure in -[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3505.16/UIApplication.m:3294
    2015-09-11 18:59:27.351 OGLES2Water[1863:58149] *** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Application windows are expected to have a root view controller at the end of application launch’

    That explains it well enough, the code in AppController.mm has:

    [_window addSubview:_glView];

    Other threads on this related error state that a call to setRootViewController is required, but I’m not sure what complies. _glView doesn’t appear to be acceptable (doesn’t compile if I change the line to

    [_window setRootViewController:_glView];

    The compiler says EAGLView can’t be the lvalue,

    It SEEMS this just requires a simple adjustment – thought someone here might know what qualifies as the UIViewController object in the typical examples provided in PowerVR SDK 3.5 (like Water)



    Update, of a kind:

    It seems this may be an iOS 9 issue, not an Xcode 7 issue. Similar inquiry, but at least if we target and build for an iOS 8.x device, the software works. An iOS 9 simulator will crash, even if the build targets older (say, 6.1) versions.



    At the risk of talking to myself ( 😉 ) I found AN answer, not sure if it’s really the RIGHT answer, but here’s what worked:

    In AppController.h of the sample, the following objective-C interface is declared

    @interface AppController : NSObject <UIAccelerometerDelegate>

    So, I changed that to:

    @interface AppController : UIViewController<UIAccelerometerDelegate>

    Then, in AppController.mm, at comment “Create a full-screen window”, where it allocates the _window member, I added:

    _window.rootViewController = self;

    Now, it launches without complaint or incident.

    The reason I think it’s not the RIGHT answer is that it is incomplete. Now, when rotating a device, the display orients in inappropriate ways, probably because it’s not controlled so as to ignore the orientation.

    At least it’s a good start.

    Thanks for reporting the issue. I’ll discuss it with the SDK team

    Apologies for the delayed response. We’ve reproduced the issue. I’ve filed a P1 bug against the SDK (BRN57583) to make sure this is fixed in our upcoming 4.0 SDK release.
