Is there no easy way to remove a specific element from an array, if it is equal to a given string? The workarounds are to find the index of the element of the array you wish
It's not clear if by quicker you mean in terms of execution time or amount of code.
In the latter case you can easily create a copy using the filter method. For example, given the following array:
let array = ["1", "2", "3", "4", "5"]
you can create a copy with all elements but "2" as:
let filteredArray = array.filter { $0 != "2" }
