Function
exists(_:_:)
Tests whether at least one element in the collection satisfies the given predicate.
func exists(_ collection: any EcoreValue, _ predicate: (any EcoreValue) throws -> Bool) throws -> BoolParameters
collection-
The collection to test
predicate-
A closure that takes an element and returns a Boolean value
Return Value
true if any element satisfies the predicate, false otherwise
Discussion
The exists operation returns true if any element in the collection satisfies the predicate. If the collection is empty, it returns false.
Examples
let numbers = [1, 2, 3, 4, 5] as [EInt]
let hasEven = try exists(numbers) { ($0 as? EInt ?? 0) % 2 == 0 }
// Result: true
