Would appreciate any suggestions, using SDK6.1 with Xcode 5 on OS 10.8

The app crashes right after the splash and does not get to the debugger at all. this happens on the TestFlight released version as well. Tried on another computer with same results. Even tried to create a new sample Monotouch app and same results.

    could you paste the full crash log? you can find it by using the Organizer in Xcode. – Stefan Fisk Jan 28 '14 at 13:36
  • this is everything that is added to the log since launching the app. there is a LOT of stuff before. but every time I try launch I get this part. – Uri Maimon - Nominal Jan 28 '14 at 13:44
  • Also noticed on the configuration that simulator has SDK6.0 and SDK7.0 while the iphone has 6.1 and 7.0 = not sure how that happened or if it related – Uri Maimon - Nominal Jan 28 '14 at 13:45
  • Xcode 5 ships with several simulator SDK (e.g. 6.0, 6.1 and 7.0) but only **one** SDK for devices (7.0). Along with the (symbolicated) crash report asked (by Stephan) a full build log (included extra `-v -v -v -v`) could give more clues. – poupou Jan 28 '14 at 13:47

Unbelievable... the solution was to install the Xcode command line tools.

This is (easily!) done from the Xcode->Preference->Downloads menu.

I have spent hours on this today, I hope this helps some other poor fellow.

  • For those that might think this isn't your issue, try it anyway. Debugging was working for me the previous day, but then broke the next. I didn't uninstall or reinstall Xcode, but when I went into the Downloads center, the Command Line tools were not installed. Not sure what uninstalled them, but this fixed my issue. – Ryan Alford Mar 07 '14 at 13:30
  • I can confirm that this worked for me. I had the exact same issue where the app crash after splash screen either in debug or testflight build on device but worked on simulator. My logs are almost the same as the above. Installing command line tools fixed it. – Dror 'Yitzhakov Jul 06 '14 at 23:06

    A million thank yous. Just had the same problem on Xcode 61.1/Yosemite and spent hours trying to solve it. Was working a few days ago, then just broke for no apparent reason. Installing the command line tools as suggested here worked, but they didn't actually show for me in the downloads center in Xcode. I had to run a terminal command to install them (xcode-select --install). I am so sick of this stuff with Xamarin. Either all the tooling runs so slowly you think it's broken, it is just broken when it worked yesterday (using VS integration anyway - I don't use XS). – Yort Feb 10 '15 at 00:42

I discovered my problem was actually something else. This will happen if your app 'takes too long to start'. I was kind of aware of this, but my app had always started fine previously and I didn't realise this was the issue.

It seems I had turned on 'break on all exceptions' and a number of components I am now using (such as Xamarin Insights, the Initialize method) throw exceptions internally which cause the debugger to break (even though you can continue from the harmless exception).

The process of capturing the exceptions and marshalling them back to VS can take quite a while (seconds sometimes), and in my case two or three of these on start-up was enough to have iOS kill the app process for misbehaving. I never actually saw the errors because the process terminated too soon for the data to come back to VS, so I didn't know what was going on.

Turning off break on all exceptions, at least until after the app starts, works around this.
