When I build my app with Xcode 8 (beta 6) and run it on an iOS 8.x device OR simulator, I get strange EXC_BAD_ACCESS crashes during app startup or a few seconds after the app launched. The crash always happens in a different spot (adding a subview, [UIImage imageNamed:], app delegate's main method etc). I don't get those crashes when I run it on iOS 9 or 10 and I don't get them when I **build** with Xcode 7 and run on iOS 8. I know this is a long shot, but has anyone else experiences something similar? Is this a known issue with Xcode 8?

Thank you very much!

I filed a radar on this issue:

Xcode 8 Produces Binary That Crashes on iOS 8 and 9 But Not 10

I reduced it to a new sample project that only prints a string literal in AppDelegate's didFinishLaunching, and it crashes on that line. It'll happen if you have also have a class in the target (but never call it at all) that references URLSessionTaskMetrics.

Having the same random crash issue on iOS 8.X with XCode 8 GM 😢, so we still submitted our latest binary that built by XCode 7 and its working fine.

Same here, compiling one of our projects with XCode 8.0 (8A218a) always crashes with EXC_BAD_ACCESS at semi-random places on an iOS 8.3 iPod while XCode 7 produces stable results. No idea how to fix this yet. We're using Swift 2.3 at the moment.

I got it fixed with the comments in the link: http://stackoverflow.com/a/39570973/6858828

One of the asset in my project has an incorrect color space "Adobe (1998)" while all other assets are RGB color space. Changing the asset to RGB color space fixed the issue for me. No more crashes in iOS 8.🙂

Awesome! The Stackoverflow post you linked to with the Bash script worked for us as well!

This solution worked for me too. I didn't use the script, but I found that I had one asset that was using an Adobe (1998) color space, so I manually converted it using GIMP & the app now seems to run fine on my test iPhone 4S running iOS 8.4.

any updates? same issue when building with latest official version of Xcode 8.

EXC_BAD_ACCESS can happen at any line of code, e.g. init a controller from storyboard or init a navigation controller.

Seems it's really related xcode asset catalog, I've fixed the crash issue by removing the P3 assets.

Just released fastlane plugin to workaround this issue.

Hi everybody,

I was under the impression that this bug was fixed in Xcode 8.1, but I still get crash reports that fit my original description. Are you guys still running into this with Xcode 8.1?

Thanks!

No longer meet this issue after XCode 8.1, I am using XCode 8.2 beta 2 now.

Make sure not to have any 16 bit or 24 bit images in your resource folders. For me it worked fine in simulator and when debugging on iOS9.0. However, the binary crashes in production! Serious XCode bug! Deleting the offending image fixes the binary, but waiting for approval of the new version is no fun.
