数组 – 在swift数组中删除对象的更好方法是什么

var testArray:[SomeObject]
let willRemoveObj:SomeObject
...

testArray = testArray.filter({ $0 != willRemoveObj })

要么

guard let index = testArray.indexOf(willRemoveObj) else {
  return
}
testArray.removeAtIndex(index)

extension Array where Element: Equatable {

    mutating func remove(object: Element) {

        if let index = index(of: object) {

            remove(at: index)
        }
    }
}

var testArray: Array<Int> = [1, 2]
let toBeRemoved: Int = 1

testArray.remove(object: toBeRemoved)

testArray

结果是

[2]
