As answered by Rob, I’ve moved the code from viewDidLoad to viewDidAppear and the problem is fixed. OR Adding self.view.layoutIfNeeded() before your code in viewDidLoad also solves the issue. In case of UITableViewCell, Inside awakeFromNib add [self layoutIfNeeded]; before updating the corner radius should solve all the issues.
It looks like there is a components(separatedBy:) on String: import Foundation let words = “apple binary cat delta echo”.components(separatedBy: ” “) print(words) IBM Playground link: http://swiftlang.ng.bluemix.net/#/repl/57868332b4e4e9971bf9f4e8
You can simply follow the diagnostic message: let randomIndex = Int(drand48().truncatingRemainder(dividingBy: Double(alphabetColors.count))) Or using arc4random_uniform(_:) would be a better alternative. let randomIndex = Int(arc4random_uniform(UInt32(alphabetColors.count)))

It consists of a predefined error domain, a domain-specific error code, and a user info dictionary containing application-specific information. Error is a Swift protocol which classes, structs and enums can and NSError does conform to. A … Read more
The easiest way to get a string’s prefix is with // Swift 3 String(string.characters.prefix(4)) // Swift 4 and up string.prefix(4) // Objective-C NSString *firstFour = [string substringToIndex:4];
Try below code let image = UIImage.init(named: “myImage”) let imgData = UIImageJPEGRepresentation(image!, 0.2)! let parameters = [“name”: rname] //Optional for extra parameter Alamofire.upload(multipartFormData: { multipartFormData in multipartFormData.append(imgData, withName: “fileset”,fileName: “file.jpg”, mimeType: “image/jpg”) for (key, value) in parameters { multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) } //Optional for extra parameters }, to:”mysite/upload.php”) { (result) in switch result { … Read more
Found this link which suggested that “The global constant was moved into a static property, and the Swift 3 migrator, as you’ve discovered, failed to correct for that. ” and that you can simply change the code to : toView.transform = CGAffineTransform.identity EDIT or even simpler: toView.transform = .identity
Here the solution for the issue. Create a new header file and name it like “your project name-Bridging-Header.h“. The file must be saved to your project folder Select your xcode project -> select your build target -> select build settings -> click the “all” option at the top -> search for Swift Compiler – General … Read more
In iOS 10, preferredStatusBarStyle is a property, not a method. So instead of overriding it with a func declaration as you’ve done, you override the getter with a var declaration: override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent } The Swift compiler’s error message here could probably be better — since it seems to know your … Read more
The syntax preferred by your swiftlint configuration is: for settingsKeys in searchResults where settingsKeys.key == settingsObject.key { settingsKeys.value = settingsObject.value try context.save() } Which is the similar to for settingsKeys in (searchResults.filter { $0.key == settingsObject.key }) { settingsKeys.value = settingsObject.value try context.save() } If you know there is only one result with the same … Read more
