Hi guys what's the most concise way to write this Swift code in Kotlin?
```        guard let type = model.type, let value = model.value, value != 5 else {
            return
        }```

Maybe you should exlain what the code does.
I for example have no idea about swift

`guard let type = model.type`  defines a new immutable variable called type if `model.type` is not null - if it is then the `else` block gets executed. Basically any statement separated by comma (acts as &amp;&amp;) after guard that is null or false will execute the `else` block.

If no guard statements are null or false then it will skip the else block.

I would probably simply do
```val type = model.type
val value = model.value
if (type == null || value == null || value != 5) {
    return
}```


But that might not be the most concise way

I guess that would be the way. I guess the difference is that in the guard statement, you can define multiple variables in a one-liner at the same time guarding from null values.

you can use early return
```val type = model.type ?: return
val value = model.value ?: return```


for this particular case it probably just should be:
```val type = model.type ?: return
val value = model.value.takeIf { it != 5 } ?: return```
