Answer 1

To start, I recommend you read this post, which provides some general background to

EXC_BAD_INSTRUCTION

.

In your case,

_Description

is an implicitly unwrapped option, so it’s likely that the crash within

Description

is caused by it being nil.

btw Some suggestions:

Swift has strong naming conventions and I recommend you follow them. To me
```
Description
```
looks like a type; a property would be called
```
description
```
. Read the API Design Guidelines for the details.
When you post code, it’s a good idea to put it in a code block (like the
```
<>
```
icon). That way it’ll be easier to read and have line numbers that you can refer to.
