You can’t simply use to compare your date to today’s date: let today = Date() let datePredicate = NSPredicate(format: “%K == %@”, #keyPath(ModelType.date), today) It will show you nothing since it’s unlikely that your date is the EXACT comparison date (it includes seconds & milliseconds too) The solution is this: // Get the current calendar … Read more
You just keep advancing the search range until you can’t find any more instances of the substring: extension String { func indicesOf(string: String) -> [Int] { var indices = [Int]() var searchStartIndex = self.startIndex while searchStartIndex < self.endIndex, let range = self.range(of: string, range: searchStartIndex..<self.endIndex), !range.isEmpty { let index = distance(from: self.startIndex, to: range.lowerBound) indices.append(index) … Read more
You can use FileManager property homeDirectoryForCurrentUser let homeDirURL = FileManager.default.homeDirectoryForCurrentUser If you need it to work with earlier OS versions than 10.12 you can use let homeDirURL = URL(fileURLWithPath: NSHomeDirectory()) print(homeDirURL.path)
Swift-3 override var prefersStatusBarHidden: Bool { return true } I got the Information From Here Change func to var Delete () Change -> to : This works because a computed variable has a getter function, so the function you were implementing before simply turns into the getter function 2016 onwards: simple Thing like On your … Read more
Please use this code: Swift 5.0, Swift 4.0 And Swift 3.0 let DocumentDirectory = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]) let DirPath = DocumentDirectory.appendingPathComponent(“FOLDER_NAME”) do { try FileManager.default.createDirectory(atPath: DirPath!.path, withIntermediateDirectories: true, attributes: nil) } catch let error as NSError { print(“Unable to create directory \(error.debugDescription)”) } print(“Dir Path = \(DirPath!)”)
As of Swift 4, there are no methods in the standard library to enumerate the elements of an OptionSetType (Swift 2) resp. OptionSet (Swift 3, 4). Here is a possible implementation which simply checks each bit of the underlying raw value, and for each bit which is set, the corresponding element is returned. The “overflow … Read more
If you’re in a Navigation Controller: ViewController *viewController = [[ViewController alloc] init]; [self.navigationController pushViewController:viewController animated:YES]; or if you just want to present a new view: ViewController *viewController = [[ViewController alloc] init]; [self presentViewController:viewController animated:YES completion:nil];
The “terminated due to signal 9” message just means your app was terminated by a SIGKILL signal. The OS sends that signal whenever your app is terminated involuntarily, whether it’s because of memory pressure (or several other reasons not relevant to this discussion), or the user explicitly killing your app by double tapping the Home … Read more
A function/variable declared as @objc is accessible from Objective-C, but Swift will continue to access it directly via static or virtual dispatch. This means if the function/variable is swizzled via the Objective-C framework, like what happens when using Key-Value Observing or the various Objective-C APIs to modify classes, calling the method from Swift and Objective-C … Read more
The type can be disambiguated using the little-known import (class|struct|func|protocol|enum) Module.Symbol syntax. import struct BTree.OrderedSet From this point on, OrderedSet unambiguously refers to the one in BTree. If this would still be ambiguous or sub-optimal in some files, you can create a Swift file to rename imports using typealiases: // a.swift import struct BTree.OrderedSet typealias … Read more
