问题 Xcode: 11.2.1 The code below is for a simple form with two components; a Picker (to select a letter) and a Text (to display the selected letter). The code compiles and runs but, when a letter is selected it does not appear in the "Selected..." text. In addition, Xcode displays a (spurious?) run time warning the first time (only) a letter is selected.. struct ContentView: View { @State private var letter = "" private let letters = ["Alpha", "Bravo", "Charlie"] var body: some View {

问题 All, I have XML in the following format: <linked-list> <Description> <desc></desc> <IP></IP> </Description> </linked-list> This XML statement could have an infinite number of <Description></Description> inside of the <linked-list></linked-list>. How should I parse this using NSXMLParser? My current code is as follows, but it parses incorrectly. @implementation XMLParser @synthesize response; - (XMLParser *) initXMLParser { self = [super init]; // init dictionary of response data response = [

问题 My project always runs correctly on all devices using Xcode 11, but after I installed Xcode 12 beta 4, it is failing to build on the simulator. I compared the build logs of Xcode 11 and Xcode 12 and it seems in Xcode 12 that my main target is being built before the cocoa pods target, and so the link will fail because the cocoapods library will not be found. How to fix the order of the build target? In Xcode 11, everything is fine. My own target is built after the cocoapods target . In Xcode

问题 Today I downloaded the release of Xcode 12.3, and I went running the iOS 14.3 simulators and it seems like there is a graphic glitch that all translucent views are yellow, dock included. I redownloaded iOS 14.2 and those seem fine. It just seems really odd. I've submitted feedback, but I was curious if anyone else has seen this? I'm on macOS v10.15.7 (Catalina) and am curious of if it's just Catalina or also macOS v11 (Big Sur). 回答1: I think it is a bug related to the discrete GPU. In
