The .isSubset()
method returns true
if all elements of a set are present in another set (passed as an argument), false
otherwise.
Syntax
setName.isSubset(of: otherSetName)
The isSubset()
method returns true
if setName
is a subset of otherSetName
, false
otherwise.
Example
let set1: Set = [2, 4, 6, 8, 10]let set2: Set = [4, 10]if set2.isSubset(of: set1) {print("set2 is a subset of set1.")} else {print("set2 is not a subset of set1.")}
In the example above, the first block after the if
statement will run if set2
is a subset of set1
. This will output:
set2 is a subset of set1.
