My Xamarin iOS app will build successfully, however, during launch it will flash a black screen and immediately return to my phones home screen exiting my app without an error. 
Upon reviewing Xamarin Studio, the status appears at top:

Waiting for debugger to connect to Phone on port 10000 view USB...

and simply hangs for ~90 seconds. Afterwards the message "Could not connect to the debugger" appears within Xamarin Studio

編譯沒問題，release也能運行，就是無法debug，app一運行就閃退，在debug log中沒有任何信息。換個iphone就好了。

Application output：

dyld: Library not loaded: @rpath/libmonosgen-2.0.dylib

今天發現解決方法了：

去掉iOS Build中Enable device-specific build，同時去掉incremental build就好了。??
