How can i use XCTAssertTrue to check it an Array is sorted – Ios swift

i want to check if a collection is sorted in my UnitTest using XCTest, does swift iOS provide any such framework or method.

let countrieds = ["Alabama","Benin","Alaska","Togo"]
    XCTAssertTrue(countrieds.sorted())

The above is just a sample and ofcourse i get the error below

Cannot convert value of type ‘[String]’ to expected argument type ‘Bool’

i will be glad to be educated on how to use XCTest to determine if a collection is sorted.

    Use

    XCTAssertTrue(countrieds == countrieds.sorted())

    or

    XCTAssertEqual(countrieds, countrieds.sorted())

    A simple way to test that is to do an assertEqual with your array.
    For exemple:

    let countries = ["Alabama","Benin","Alaska","Togo"]
XCTAssertEqual(countries, countries.sorted())

    (In this exemple the test will return false obviously)
