I don't think there was a crash, that I could tell. I went around and around with this on Saturday - eventually just made a brand new Xcode project and added the code into it. I found the culptrit that way. When I added the build phase step to copy the executable to the directory I wanted, it failed when the copy was run. There's a checkbox in the copy phase that says 'code sign on copy' or something like that. When I checked that, it started working again. I never had that checked before, or maybe the checkbox wasn't even there before, and it was fine until yesterday.

This morning I started getting this after recompiling a little terminal program I use when making my game. This is so annoying - we can't even compile and run simple apps made with Xcode on our own machines?

What I had to do to solve this was create a Launch Screen storyboard and hook it up in my targets settings and specify it as the initial storyboard. That gave it whatever information it needed to know it was a full-screen app.

Ugh I cannot even explain the solution because of this forum's HTTP rules.  Hence the spaces in these URLs... And even once I correct them, the buggy forum software doesn't recognize I've done it. I have to start over. So for anyone else getting this, I managed to fumble through it.  Using the 'ptv2' site I was able to send my POST without problem.  That made me think the problem was on the server side.  Then I read online about how people were seeing POSTs converted to GETs when the data was empty - or when there was a redirect.  What solved it for some people was changing 'www .mysite.com' to 'mysite.com'.  I tried this, but it did not work for me.  However, it may have been one step in the solution, something I needed to do. I confirmed on the PHP side that it did indeed think it was getting a GET and not a POST.  But why though... I noticed that when I went to 'http : //mysite.com', in the browser it was being converted to 'https : //mysite.com'. That was the solution. I needed to change 'http' to 'https' (and probably, " www .blah.com" to "blah.com").

Did you find the answer to this? I have the same issue.

Did you ever find the answer to this? I have the same problem.

Contacted Apple Developer Support and they helped. I needed the updated Apple Worldwide Developer Relations Intermediate Certificate.

To follow up on this. If I run the product outside of XCode and then look at the crash report, it shows this: Crashed Thread: 0 Exception Type: EXC_CRASH (Code Signature Invalid) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Termination Reason: Namespace CODESIGNING, Code 0x1 So seems like a code-signing thing. But I regenerated my profiles from the new certificate and it isn't showing my any kind of signing warnings or errors in XCode?
