There are 2 overloads of print (2 different functions with the same name) – this one and this one. If you just say print, it is ambiguous which overload you mean. Therefore, you also specify the parameter labels of the functions, so the first overload is called print(_:separator:terminator:) and the second is called print(_:separator:terminator:to:). Let’s … Read more
You can simply call switch.isOn to get the state of the UISwitch, but you should rather create an IBAction for your UISwitch, which will be called every time the state of the Switch changes. You can store the switch state in a computed property if you don’t need to be notified every time the state … Read more
You can’t get NSArray with UInt16 elements because NSArray can contain only NSObjects, so you have to wrap UInt16 to NSNumber or use some other container (for example, simple c array). The closest code will be something like this: // Just preparing some test data NSMutableData *data = [NSMutableData new]; for (int i = 0; … Read more
As @SeyyedParsaNeshaei says, there is another answer that gives a “marquee” type scrolling, however, if what you want (as you say) is one word at a time, consider the following little sketch, which will run in Playground. It basically sets up a timer that changes the text of a UILabel one word at a time. … Read more
class Point { let x: Int let y: Int init(x: Int, y: Int) { self.x = x self.y = y } } class Rectangle { let nw: Point let se: Point init(nw: Point, se: Point) { self.nw = nw self.se = se } func area() -> Int { return (se.y – nw.y) * (se.x – … Read more
I believe you could set a local notifications that will fire each 24 hour then display any quote. So a day contains 86400 seconds, we could use a timer that will count down from 86400 seconds to zero, when it hits zero we reset the timer and remind them a quote @IBOutlet weak var label:UILabel! … Read more
func pieChart(pieChart:XYPieChart!,index:Int!) ->CGFloat { let value:NSNumber = self.values[index] as NSNumber return value.doubleValue } 2 solved How do I re-write this code in Swift? [closed]
Use this : //Define your function like this func initWithAnnotation(annotation:MKAnnotation, reuseIdentifier:String, completion: ()->Void) { //Your implementation goes here //for call back completion() } //call above function by this: self.initWithAnnotation(Your_MKProtocol, reuseIdentifier: “identifier”, completion: { //Your call back implementations //Similar to delegate callback }) solved How to write following method in swift?

Here is a possible way: var letters: [Character] = [“a”, “b”, “c”, “d”] let insertionIndex = newArray[0] .index(newArray[0].startIndex, offsetBy: 5) for index in newArray.indices { newArray[index].insert(letters[index], at: insertionIndex) } And you could check the result this way: newArray.forEach { print($0) } Which prints: self.aButton.setTitle(“?”, for: .normal) self.bButton.setTitle(“?”, for: .normal) self.cButton.setTitle(“?”, for: .normal) self.dButton.setTitle(“?”, for: .normal) … Read more
As per my comment, this is a task for DateFormatter rather than RegeX. I threw this together in a playground quickly to demonstrate what I mean. let inFormatter = DateFormatter() inFormatter.locale = Locale(identifier: “en_US_POSIX”) inFormatter.dateFormat = “yyyy-MM-dd’T’HH:mm:ssZZZZZ” let input = “2019-03-11T17:04:00+0100” let dateFromInput = inFormatter.date(from: input)! // This should be unwrapped properly in your code. … Read more
then you can make a loop to make a dictionary that later will be appended to arrayDictionary let array = [[String:Any]]() for item in data { let dictionary = [String:Any]() dictionary[“object1”] = item.id dictionary[“object2”] = item.name dictionary[“object3”] = item.address array.append(dictionary) } 2 solved How to write nested dictionary in Swift 4 [closed]
You need to check whether an array has an element or not. if addonCategory.count > 0 { // array has element } else { // array hasn’t element } Alternatively you can use guard let or if let to check. Using if let if let addonCategory = subCategoryModel[tappedIndex.section].items[tappedIndex.row].addonCategory, addonCategory.isEmpty { print(addonCategory) print(“Hello”) } else { … Read more
Try this : NSSortDescriptor * sortDescriptors = [[NSSortDescriptor alloc] initWithKey:@”name” ascending:YES]; // change your key here NSArray * arrSortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSArray * sortedArray = [yourArray sortedArrayUsingDescriptors:arrSortDescriptors]; NSLog(@”sortedArray %@”,sortedArray); 0 solved Sort a dictionary array when the key is given as the parameter
I found the answer I was looking for on this apple site. Here is how I managed to get it work: first you transform the filepath string into NSURL(and make CFURL of that) like this: let path : NSString = filepath as NSString let thePath = path.stringByExpandingTildeInPath let url = NSURL.fileURLWithPath(thePath) let CFUrl = url … Read more
This is rough translation to Swift…no tested. // Define some colors. var darkGray: UIColor = UIColor.darkGrayColor() var lightGray: UIColor = UIColor.lightGrayColor() // Navigation bar background. UINavigationBar.appearance().barTintColor = darkGray UINavigationBar.appearance().tintColor = lightGray // Color of typed text in the search bar. var searchBarTextAttributes: [NSObject : AnyObject] = [NSForegroundColorAttributeName: lightGray, NSFontAttributeName: UIFont.systemFontOfSize(UIFont.systemFontSize())] UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).defaultTextAttributes = searchBarTextAttributes // Color … Read more
