iOS Question Problem with debugging

[Filippo]

Hi,

the app is compiled without error in debug mode, but on startup it crashes with this error message.
How am I supposed to find an error when an error like this is displayed during debugging?
There should be some more information here.

Application_Start
Error occurred on line: 83 (Main)
Target is null. Method called: _initialize:::

or does the line 83 have to do with this file?

I think it should be something with Initialize keyword.

The error happens in the designer script.

The error happens in the designer script.

I have found the layout with the error.
With about 20 layouts it is not so easy to find the error, especially if you open the layouts with the disgner and no error message is displayed.
It would be nice if the compiler would display the layout name that causes the error.

In any case, thank you for the answer.
