UNUserNotificationCenter.current().getPendingNotificationRequests { DispatchQueue.main.async{//Contextual closure type '() -> Void' expects 0 arguments, but 1 was used in closure body let str:String = "" self.finalresulter.text = str self.finalresulter.text = "\($0.map{$0.content.title})" } } You are using $0 inside async { } closure. This closure expects no arguments, which means using $0 argument shortcut is invalid. You are evidently attempting to refer to requests array from getPendingNotificationRequests callback. The reason you can't by using $0 is that it's screened by DispatchQueue

I put Navigation bar inside UICollectionView in swift 4. When I scroll the collectionView, it does not goes to back layer and it overlaps to Navigation Bar. self.collectionview.contentInset = UIEdgeInsetsMake(40, 0, 0, 0) I also write this code but it does not work. I also unselect the "Under Top Bars" in Extend Edges in Attributes Inspector. All the ways do not work. Can anyone help me please? 来源： https://stackoverflow.com/questions/46376475/uinavigationbar-does-not-overlap-to-uicollectionview-in-swift-4

I'm having an issue in my cellForItemAtIndexPath where I am setting an image to my cell's UIButton but every time I scroll the collectionView's cells, it's placing the image on top of the already set image again and again. I can tell because the shadow of the image is getting thicker and thicker. I'm pulling the images from an array that I created of image literals in that swift file and the correct images are loading so there's no problem there. I'm sure this is a simple fix for most but I can't seem to find an answer anywhere. Image of my cellForItemAtIndexPath function My app running before

As of the release of iOS11 it has been a pain (if not impossible) testing in-app purchases. While I've found a great workaround for testing on iOS here: https://stackoverflow.com/a/46467498/4514671 I could not find anything for macOS apps. So here is what I did that kind of does the same as with the iOS workaround: In the App Store app Sign Out of your account (Store/Sign Out) In iTunes Connect create a brand new Tester Restart your computer Open your Xcode project Build & run Click on your Buy button to start a purchase Sign in with your newly created test account When prompted to Change the

I am trying to pass data BACK to the previous viewController using delegates. Does anyone know how to pass data back from ViewController B to ViewController A ? So I want to pass data from SecondVC to FirstVC and update custom table view cells with the data from SecondVC 4 address text fields but for some reason, it's not updating at all. Any help will be much appreciated as I'm just at the beginning level so tried all sorts of things but not able to get it to work. FirstVC import UIKit class MainVC: UIViewController, UITableViewDelegate, UITableViewDataSource, DataSentDelegate { @IBOutlet

I've just added a new RichNotification Extension to my project. Now I've got "myApp" target and two targets for: "RichNotification" and "RichNotificationContent" When I archive the main target for the App Store works fine but I get this error while trying to upload to the App Store: ERROR ITMS-90700: "Incorrect Platform. You included the iOS arm64 executable “myAPP.app/PlugIns/myAPPRichNotifications.appex/myAPPRichNotifications” in your iOS bundle. Only iOS executables can be included." Is there any special procedure to archive an app with multiple extensions / targets? Special build config?

The new HIG for iPhone X available here , specify: "Provide a full-screen experience. Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom." Now I'd like to understand how to accomplish that with Xcode 9 GM, since it seems to me that the only view allowed to extend to the whole screen is the UIViewController root view, and that whenever I try to drag constraints for a view above that, i.e. WKWebView to the root view, the constraints get actually connected to the safe area, leaving both

Xcode 9 seems to be reporting a lot of Main thread calls to UIApplication properties. Even though the UI is not being updated this is particularly cumbersome due to the extension of logs it produces a default environment. 4 TestApp 0x0000000101c262e0 __39-[ViewController viewDidLoad]_block_invoke + 196 5 libdispatch.dylib 0x0000000102279654 _dispatch_call_block_and_release + 24 6 libdispatch.dylib 0x0000000102279614 _dispatch_client_callout + 16 7 libdispatch.dylib 0x0000000102289008 _dispatch_queue_serial_drain + 716 8 libdispatch.dylib 0x000000010227ce58 _dispatch_queue_invoke + 340 9
