Hey Kotlin fam!
I'm sure there must be a more efficient way to do this, can't quite think of what though...

Determine whether a list of objects contains an object with a specified property value?
Example (bad):

data class Objects(
    val objects: List<MyObject>
) {

    fun containsFirstProperty(value: String): Boolean {
        var itDoes = false
        objects.forEach {
            if (it.firstProperty == value)
                itDoes = true
        }
        return itDoes
    }
}

data class MyObject(
    val firstProperty: String,
    val secondProperty: String
)

Thanks!

objects.any { it.firstProperty == value }

EXACTLY! 🙂

I do this with an extension function on List, at least for your specific example that would be better than creating a whole Objects class.
