It changed a bit, here is the new syntax: 0.stride(to: 10, by: 2) and Array(0.stride(to: 10, by: 2)) // is [0, 2, 4, 6, 8] if you take a look at here, you can see what types conform to the Strideable protocol. As @RichFox pointed out, in Swift 3.0 the syntax changed back to the … Read more
Add background and apply shadow to it, like in below example VStack { … } .background(Color.white // any non-transparent background .shadow(color: Color.red, radius: 10, x: 0, y: 0) ) .frame(width: geometry.size.width, height: geometry.size.height)
You can use NSPredicate to filter elements. let searchText = “the content of the staticText” let predicate = NSPredicate(format: “label CONTAINS[c] %@”, searchText) let elementQuery = app.staticTexts.containing(predicate) if elementQuery.count > 0 { // the element exists } With CONTAINS[c] you specify that the search is case insensitive. Have a look at Apples Predicate Programming Guide
You don’t have to pass an argument at all. All you have to do is to specify enum type as generic argument and ObjectMapper will take care for all enum initialization procedures. typeEnum <- (map[“type”],EnumTransform<LevelType>())
You can simply use hasher.combine and call it with the values you want to use for hashing: func hash(into hasher: inout Hasher) { hasher.combine(index) hasher.combine(title) }
The initializers expect named arguments. extension UIFont { func sizeOfString (string: String, constrainedToWidth width: Double) -> CGSize { return NSString(string: string).boundingRectWithSize(CGSize(width: width, height: DBL_MAX), options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: self], context: nil).size } } Note: Strings can be cast to NSStrings. extension UIFont { func sizeOfString (string: String, constrainedToWidth width: Double) -> CGSize { return (string … Read more
I have created a UIResponder extension with a recursive method that you can use in any UIView (which inherits from UIResponder) to find a parent view of a specific type. import UIKit extension UIResponder { /** * Returns the next responder in the responder chain cast to the given type, or * if nil, recurses … Read more
You can use the .updating modifier like this: struct TapTestView: View { @GestureState private var isTapped = false var body: some View { let tap = DragGesture(minimumDistance: 0) .updating($isTapped) { (_, isTapped, _) in isTapped = true } return Text(“Tap me!”) .foregroundColor(isTapped ? .red: .black) .gesture(tap) } } Some notes: The zero minimum distance makes … Read more
That’s not a workaround, it’s how you do it in SwiftUI. Two things: There used to be a cornerRadius modifier that became deprecated in… beta 4? beta 5? Yes, it’s been a moving target. With a great amount of thanks to @kontiki (blog post), here’s an extension that nicely returns what you want: extension View … Read more
Using this protocol, KeyboardReadable, you can conform to any View and get keyboard updates from it. KeyboardReadable protocol: import Combine import UIKit /// Publisher to read keyboard changes. protocol KeyboardReadable { var keyboardPublisher: AnyPublisher<Bool, Never> { get } } extension KeyboardReadable { var keyboardPublisher: AnyPublisher<Bool, Never> { Publishers.Merge( NotificationCenter.default .publisher(for: UIResponder.keyboardWillShowNotification) .map { _ in … Read more
