I want to enumerate my array of Any objects, with access to index of element. However, swift throw an error:
Type '() -> EnumeratedSequence<[Any]>' does not conform to protocol 'Sequence'`
My code is:
var arrValues : [Any]!
for (index, ob) in arrValues.enumerated() {
print("\(index): '\(ob)'")
}
How to fix that?
You need to follow correct syntax, I thought you are doing like below image,
But, the actual code is,
for (index, ob) in arrValues.enumerated(){
//.....
}
Also, you need a Optional var for check it has value or not.
var arrValues : [Any]?
if arrValues?.count != nil{
for (index, ob) in (arrValues?.enumerated())! {
print("\(index): '\(ob)'")
}
}else{
print("Array is Empty")
}
Output:

This is the way you go
var arrValues = [Any]()
for var i in 0..<arrValues.count {
print("\(i): '\(arrValues[i])'")
}
This will also work
var arrValues = [Any]()
for (index, ob) in arrValues.enumerated() {
print("\(index): '\(ob)'")
}
0 ..< arrValues.count manually. You can just use the indices property of your collection: for i in arrValues.indices. Also, why are you manually incrementing i? Swift will do that automatically.Looks like you are declaring an array without creating its instance.
You can use below snippet:
var arrValues = [Any]()
for (index, ob) in arrValues.enumerated() {
print("\(index): '\(ob)'")
}
