#warning: C-style for statement is deprecated and will be removed in a future version of Swift

I just download a new Xcode (7.3) with swift 2.2.

It has a warning:

> C-style for statement is deprecated and will be removed in a future version of Swift.

How can I fix this warning?

Removing `for init; comparison; increment {}` and also remove `++` and `--` easily. and use Swift's pretty for-in loop



// WARNING: C-style for statement is deprecated and will be removed in a future version of Swift
for var i = 1; i <= 10; i += 1 {
print("I'm number \(i)")
}
------------
**Swift 2.2:**

// new swift style works well
for i in 1...10 {
print("I'm number \(i)")
}
------------
**For decrement index**

for index in 10.stride(to: 0, by: -1) {
print(index)
}

Or you can use `reverse()` like

for index in (0 ..< 10).reverse() { ... }


------------
**for float type `(there is no need to define any types to index)`**

for index in 0.stride(to: 0.6, by: 0.1) {
print(index) //0.0 ,0.1, 0.2,0.3,0.4,0.5
}

--------------
**Swift 3.0:**

**From `Swift3.0`, The `stride(to:by:)` method on Strideable has been replaced with a free function, `stride(from:to:by:)`**

for i in stride(from: 0, to: 10, by: 1){
print(i)
}

For decrement index in `Swift 3.0`, you can use `reversed()`

for i in (0 ..< 5).reversed() {
print(i) // 4,3,2,1,0
}

-------------------
Other then `for each` and `stride()`, you can use `While Loops`

var i = 0
while i < 10 {
i += 1
print(i)
}

*`Repeat-While Loop:`*

var a = 0
repeat {
a += 1
print(a)
} while a < 10

For this kind "for" loop:

for var i = 10; i >= 0; --i {
print(i)
}

You can write:

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

> Blockquote

Use this instead

if(myarr.count)
{
for i in 1...myarr?.count {
print(" number is \(i)")
}
}

I got the same error with this code:

for (var i = 1; i != video.getAll().count; i++) {
print("show number \(i)")
}

When you try to fix it with Xcode you get no luck... So you need to use the new swift style (for in loop):

for i in 1...video.getAll().count {
print("show number \(i)")
}
