Check if an object is the last in the array

Question

I have an array of [myObject] called myArray and an myObject object.

I want to check if myObject is the last object in myArray.

What is the best way to do it?

I've tried:

if myObject == myArray.last!

but it gives me this error:

Binary operator '==' cannot be applied to two 'myObject' operands

Any idea? Thanks!

Have you tried "isEqualTo:"? Have you debugged that both the object are of same type/class? — Bharat Modi, Jul 13 '16 at 12:27
Your object has to conform to Equatable. I have an example here: http://stackoverflow.com/a/32953118/2227743 — Eric Aya, Jul 13 '16 at 12:28
if you need to compare custom objects then those should conform to equatable protocal. Please see http://nshipster.com/swift-comparison-protocols/ — Saikiran Komirishetty, Jul 13 '16 at 12:29
Try the operator === This operator compare reference in memory — Adolfo, Jul 13 '16 at 12:29
You need your `myObject` class to implement the `Equatable` protocol. Also the class name should be `MyObject` — Paulw11, Jul 13 '16 at 12:30
question is similar to http://stackoverflow.com/questions/24467960/swift-equatable-protocol — Saikiran Komirishetty, Jul 13 '16 at 12:31
Please study the answer in the duplicate link. There's also other examples on SO, of course, if you still struggle with the concept. You should also read the Swift manual, where protocols are explained. — Eric Aya, Jul 13 '16 at 12:34

Try this one may be work for you.

let ary = ["1","2","3"]

if ary[0].isEqual(ary.last!){
    print("Is last object")
}else{
    print("Is Not last object")
}

Your output should be:Is Not last object

let ary = ["1"]

if ary[0].isEqual(ary.last!){
    print("Is last object")
}else{
    print("Is Not last object")
}

Your output should be:Is last object

OP has an array of *objects* (class or struct instances for example), not an array of strings. – Eric Aya Jul 13 '16 at 12:35
Here you can try compare any type of object. – Hitesh Surani Jul 13 '16 at 12:36
No. It doesn't work for class/structs instances if they do not conform to Equatable. You should read the link I've given to OP... – Eric Aya Jul 13 '16 at 12:37
