For Loop Swift With Code Examples

This article will present you, by way of a sequence of examples, find out how to repair the For Loop Swift drawback that happens in code.

```for i in 0...10 {
print(i)
}

let array = Array(0...10) //identical as [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

for worth in array {
print(worth)
}
```

The resolution to the beforehand talked about drawback, For Loop Swift, can be present in a distinct technique, which will probably be mentioned additional down with some illustrative code.

```for n in 1...5 {
print(n)
}

// Output: 1 2 3 4 5
```
```var someInts:[Int] = [10, 20, 30]

for index in someInts {
print( "Value of index is (index)")
}```
```for val in sequence{
// statements
}```
```// create a loop assertion
for i in 1...3 {
print("Hello, World!")
}```

With quite a few examples, we have now seen find out how to resolve the For Loop Swift drawback.
