问题 Today again one combine problem I currently run in and I hope that someone of you can help. How can normal unit tests be written for ObservableObjects classes which contain @Published attributes? How can I subscribe in my test to them to get the result object which I can assert? The injected mock for the web service works correctly, loadProducts() function set exactly the same elements from the mock in the fetchedProducts array. But I don't know currently how to access this array in my test

问题 I am trying to create a profile page, in which there is a form at the bottom with various options. However when I insert a Spacer( ) into the VStack , the form does not move to the bottom of the screen, as it should do. I tried replacing the Form with a Text and it worked fine, moving to the bottom of the screen. So I'm assuming it has something to do with the form. Here is my code struct Profile: View { @Environment(\.presentationMode) var mode: Binding<PresentationMode> var body: some View

问题 I'm trying to store a lot of images for a project in xcassets. Around 2,000. However, they are all very small/highly optimized at only around 3-5kB each, so the overall total will be maybe 6-10MB. Is this going to cause a memory problem? Is this not recommended? I know I could have the user download them from a server on a need basis, but it would be easier if I could include them all right from the app download. 回答1: How many images can you store in XCAssets? Well... As per Apple on Maximum

问题 I’m building an app which handles notifications pushed from Parse, and trying to create a notification history function. I’ve enabled the background modes successfully, so when the app is running in the background, the app can get the payload well via application:didReceiveRemoteNotification:fetchCompletionHandler even the banner/alert is not tapped. However, when force-quit / swipe up to kill the app, application:didReceiveRemoteNotification:fetchCompletionHandler is not called. Is there any

问题 So I have a dynamic link that is working in that it opens up the app when I click on it but the handling of the dynamic link doesn't happen. This is because application function seen below is never entered and I'm not sure why... func handleIncomingDynamicLink(_ dynamicLink: DynamicLink){ guard let url = dynamicLink.url else { print("That's weird. My dynamic link object has no url") return } print("Your incoming link parameter is \(url.absoluteString)") } func application(_ application:

问题 I have two NSDecimalNumbers and I need to apply one to the power of the other, originally this code was using doubles and I could compute this with the pow() function like this: double result = pow(value1, value2); The problem I have is I am converting the code to use NSDecimalNumbers and although they include the method toThePowerOf, it only accepts int values. At the moment the only solution I have to this problem is to convert the NSDecimalNumbers Temporarily but this results in a loss of

问题 While working in Swift project, I have two modules, let's say Base Feature Base has a SHService class from where I am calling a function of Feature module (of class SHCommon ). Feature module is building without error but Base raises error in linking phase. Snapshot of workspace: Base.SHService import Foundation import Feature class SHService { public func printMe(printString: String){ SHCommon().printMe(printString: printString) } } Feature.SHCommon import Foundation public class SHCommon {
