iOS 9 beta 3 crash on startup

marius — Wed, 15 Jul 2015 01:39:02 GMT

Hello,

Apps build with the latest iOS SDK (10.2.4) crash on iOS 9 beta 3 (new built apps but also apps already in the store).

I've created a small test app bamse16/TestEsriiOS9 · GitHub so you can have a look.

I am aware that we're talking about iOS beta, and that is not a priority, but I'm worried that if this bug is not addressed (by Esri or Apple), we'll all be sad when iOS 9 will be released to the public.

Thank you,

Marius

Does this happen in the simulator or just on a device?

We're aware of the on-device issue and are investigating.

My recommendation from my own experience, for now, is to revert to iOS 9 Beta 2 and Xcode 7 beta 2 if you're using a device.

The crash happens with both Collector, Exporer and AppStudioPlayer in iOS 9 public beta.

Good to know. I'll pass that on to the team, thanks.

The bug happens only on the device (iPad mini retina 1) and it works fine on the simulator. But as Hector says, I believe it affects all the apps using the ESRI SDK.

I can confirm here at WSDOT that our app, using the latest ESRI iOS SDK, crashes on iOS 9 beta 3, but only on device. Have tested on a iPad Mini 2 and an Air 2. Works fine in simulator so we can continue to make changes and test for IOS 9 support for now.

I also had added a bug report to apple on this issue. They asked the following, may be worth to pass on to development:

We need more information to investigate this issue.  It looks like the pointer is being passed directly from the app to pthread_mutex_init  (nothing changes x0 before this stlr) and is misaligned (because it contains a pointer it should be 64-bit aligned, but it’s not: 0x12cd07564 == 4 (mod 8))  That address looks like it might be somewhere in the heap to us. How are you obtaining the pthread_mutex_t pointer that you pass in?

This crash bug appears to be fixed by apple in Beta 4, which was released today.

Hey Joshua,

That's great. I just tested this and yeah, my apps are working again in Beta 4.

Note that in the app I'm working on I had to modify my info.plist to allow arbitrary loads for the appropriate target(s):

(For more details, see Networking with NSURLSession - WWDC 2015 - Videos - Apple Developer)

That's way too broad, but I just wanted get moving again

Thanks for posting the update!

Nick.

Hi Nick,

I can confirm that apps already in the store load the maps properly, and do not crash on iOS 9 beta4 anymore.

Regards,

Marius
