“Expected ';' after top level declarator” under Swift

问题

I'm trying to set all my colours in one Swift file that can be used throughout my application.

The following code below results in...

import Foundation
import UIKit

class DotColors {

let tsblueColor = UIColor(red:58/255.0, green: 125/255.0, blue: 208/255.0, alpha: 1.0)

}

... Expected ';' after top level declarator

回答1:

The same error occurred to me after I've added the first swift file to my objc project. That's how I fixed it:

1. Make sure you use an "iOS Source" file (not "OS X Source") when you've added the file.
2. Don't import the swift file in your objc file like: #import "ExampleFile.swift" but use #import "ProjectName-Swift.h"
3. Make sure you use @objc statements in your swift code that you want to import to objc

You forgot to import UIKit.

import UIKit

You can try this,

import Foundation
import UIKit

class DotColors {

  let tsblueColor = UIColor(red:58/255.0, green: 125/255.0, blue: 208/255.0, alpha: 1.0)

}

Try putting

import UIKit

In the top. Think that will solve your problem!

回答4:

I got this error, persisting even once i made the appropriate code changes, after accidentally selecting an OS X Source Cocoa Class in the new file prompt, instead of an iOS Source Cocoa Touch Class.

Try creating a new swift file that you're sure is kicked off as iOS.
