Description anton.tropashko 2015-06-12 06:55:22 UTC
app crashes shortly after splash screen on ios7 device.

I'm on beta cause you stable trips some watchdog and I'm getting off breakpoints on ios

It looks like https://bugzilla.xamarin.com/show_bug.cgi?id=22750
re-breakage
Comment 1 Sebastien Pouliot 2015-06-16 15:53:24 UTC
Bug #22750 was a simulator only issue.

If this crash on a device then we'll need to have:

1. the full versions* you're using (all products);

2. a build (one done with `-v -v -v -v`) log so we can see what and how the build was done (e.g. all options); and 

3. the symbolicated crash report to see what's going on the device


* The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).

Look, I can't even select an ios simulator target other than 8.3!

which executable do you want me to run
Comment 4 Sebastien Pouliot 2015-06-22 08:25:46 UTC
> I can't even select an ios simulator target other than 8.3!

That's either an Xcode issue [1] (our tool request the list of available simulators from Xcode) or you set up your project to require iOS 8.3 (or later) version (our tools filters the simulator based on the minimum requirement for the app bundle).

> which executable do you want me to run

Please re-build the executable that crashed.
Comment 5 anton.tropashko 2015-06-22 08:37:05 UTC
ok. you are right I'm downloading 7.1 simulator in xcode


 ./client/ConsumerApp/ConsumerApp/ConsumerApp.iOS/bin/iPhoneSimulator/Debug/ConsumerAppiOS.exe -v -v -v -v

required .Net I'm pulling it now but I wonder if that's the app you needed the build info for
Comment 6 Sebastien Pouliot 2015-06-22 08:43:23 UTC
No, I want to build logs that create the ConsumerAppiOS.exe app bundle (#2 from comment #1).

In your project options you should see a place where you can add "Additional mtouch arguments", that's where you add the "-v -v -v -v". Those will augment the verbosity of the build to show more details.
Comment 7 anton.tropashko 2015-06-23 05:31:07 UTC
not sure that additional -v -v -v -v in mtouch arguments for ios
had provided you with any additional info

Comment 8 anton.tropashko 2015-06-23 05:33:31 UTC
forgot to mention: it starts fine on 7.1 simulator
(but not on the real device)

it seems that you are using UIAlertAction which was added in ios 8.0
the Xamarin Forms control needs to check first if that functionality is available
Here's some pseudocode that could get you started on a 7.x fallback
for the xamarin forms alert control
http://stackoverflow.com/questions/24058543/alert-that-can-work-on-ios-7-0-and-8-0
Comment 10 Sebastien Pouliot 2015-06-23 08:23:01 UTC
Note: you build log is incomplete (maybe you did not clean before ?).

Anyway you're right, UIAlertAction is only available on iOS 8+ IIRC that's not a new issue, are you using the latest X.Forms ?

I'm updating the bug's component so the Forms team can have a look at it - and tell you how to work around it.
Comment 11 anton.tropashko 2015-06-23 10:05:57 UTC
I'm on beta channel since "stable" was tripping ios watchdogs
debugging was not possinle

"Anyway you're right, UIAlertAction is only available on iOS 8+ IIRC that's not
a new issue"

could you point me at the duplicate bugzilla bugreport for UIAlertAction
erroneously used by xforms on ios versions prior to 8.0?
It could very well be not a new issue but its blocking
deployment to 7.x devices
I'd love to see the ETA in that dup bug report tracking the issue

The build log was only for the ios section

Thank you for taking the time to submit the bug. I'm unable to reproduce the issue you are having given the comments. Please attach the project you are trying to compile and we'll try to compile it on our latest iOS builds. 

Warm regards,
Xamarin Forms Team
