Question or problem with Swift language programming:
After upgrading Xcode to 7.3, I just found that some modules are stricken out while importing, like in this screenshot:
But after adding the module (so just pressing enter) everything is fine. What does that mean? The module here is written in Swift and works fine.
How to solve the problem:
This is a bug. We have fixed it in 218010af, which should be included in the Swift 2.2.1 release and is included in the 2016-04-12-a developer snapshot.
The strikethrough occurs if you try to import a module that has already been imported by your file or module:
In this case, I have already imported Foundation (which implicitly imports CoreFoundation), so Xcode is telling you that there is no need to import either module again.
It usually happens when a framework is already imported by any other framework you have already been imported.
For example, UIKit is already imported with Foundation so you don’t need to import it manually.
I changed the order of the imports
import Foundation import UIKit import LayerKit import Atlas < red line import Foundation import UIKit import Atlas import LayerKit
Some notes that may be causing it:
LayerKit importing Atlas even though LayerKit is the lower level API
Atlas is the UI layer
Both were Cocoapod imports
Error appeared when I created an 2nd Schema for App Store/Enteprise
releases and cleaned one and switch to the other.
- Deleting Derived
Data didnt clear it.
- So tried rearranging them and red line disappeared
