Remove Specific Array Element, Equal to String - Swift

Question

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

Answer 1

You could use filter() in combination with operator overloading to produce an easily repeatable solution:

func -= (inout left: [String], right: String){
    left = left.filter{$0 != right}    
}

var myArrayOfStrings:[String] = ["Hello","Playground","World"]

myArrayOfStrings -= "Hello"

print(myArrayOfStrings)   // "[Playground, World]"

Answer 2

if you need to delete subArray from array then this is a perfect solution using Swift3:

var array = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j"]            
let subArrayToDelete = ["c", "d", "e", "ee"]
array = array.filter{ !subArrayToDelete.contains($0) }
print(array) // ["a", "b", "f", "g", "h", "i", "j"]

this is better for your performance rather than deleting one by one.

btw even faster solution is (but it will rearrange items in the final array):

array = Array(Set(array).subtracting(subArrayToDelete))
