EXC_BAD_ACCESS KERN_INVALID_ADDRESS ios < 9.3 xcode 10

Question

with latest xcode I'm having a crash only on ios 9.0>9.2.x

13 UIKit                          0x27199959 -[UIViewController view] + 24

The crash happens in this code: (Inside viewDidLoad)

[super setDelegate:self];
[super viewDidLoad];
[self backgroundImageView];

if (!_backgroundImage)
    [self setBackgroundImage:[UIImage imageNamed:@"BkImage"]];

the [self backgroundImageView] just initialize a UIImageView with the frame as the self.view and the setBackgroundImage just set an image taken from the XCAsset folder.

-(UIImageView *)backgroundImageView {
    if (!_backgroundImageView)
    {
        _backgroundImageView = [[UIImageView alloc] initWithImage:self.backgroundImage];
        [self.view insertSubview:_backgroundImageView atIndex:0];
        [_backgroundImageView setFrame:self.view.bounds];
        [_backgroundImageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
    }
    return _backgroundImageView;
}

-(void)setBackgroundImage:(UIImage *)backgroundImage {
    _backgroundImage = backgroundImage;
    if (self.forceNoBackground)
    {
        [self.backgroundImageView setHidden:YES];
        return;
    }
    else if (_backgroundImageView) [self.backgroundImageView setImage:backgroundImage];
}

As you can see from the log the crash happens right after the uiimage is set.

I have other crashes only on ios 9 always for a Bad Access.

The target is set to deployment target to 9.0, but the project was set to 8.3 Project deployment target

could this be the cause? Should i move the image out of the XCasset folder?

Thank you very much.

Show the contents of `backgroundImageView` and `setBackgroundImage` methods — mag_zbc, Oct 04 '18 at 09:21
The contents are irrelevant, the crash does not happen inside the methods, the crash happens in `viewDidLoad` and then directly inside in `imageNamed:`. There does not seem to be anything wrong with your code in this situation but with the image / asset itself. — luk2302, Oct 04 '18 at 09:25
Thank you for the answer: i edited the question. As luk2302 said i don't think the problem is here. — MajinDageta, Oct 04 '18 at 09:33
According to Xcode 10.1 changelog, this is a known issue: "*[Resolves an issue that affected app compatibility with iOS 9.0, 9.1 and 9.2. Apps containing asset catalogs built with Xcode 10 whose deployment target was set to iOS 9.0, 9.1 or 9.2 would produce content incompatible with the runtimes of those iOS versions. Rebuilding the application with Xcode 10.1 resolves this issue. (44535967)](https://developer.apple.com/go/?id=xcode-10.1-beta-rn)*" — Cœur, Oct 08 '18 at 07:43
