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 In XCode 12, if I create a new SwiftUI App and check the "Use Core Data" button, the resulting application (with no changes) shows a blank screen in simulator (as well as on a device). In preview it shows the example timestamps as expected. Why are the simulator/device not showing the example timestamps? 回答1: If you want to see the sample inputs from the template (10 rows with timestamp) in your simulator, you need to change in App.swift: let persistenceController = PersistenceController

问题 Anyone else having issues with the GM release with ML models and has a solution for this? I get the following error: Type 'MLModel' has no member '__loadContents' I have cleaned the Project + deleted derived data (this is a generated file that is put into the derived data folder) I notice that the method should not be there for mac OS 10.15 which I use, but it there for some reason. I also noticed that this API is still in beta while the GM is a production build? https://developer.apple.com

问题 I decided to switch from wrapping MKMapView into a UIViewRepresentable to the new Map() in SwiftUI. I was able to display correctly a MKMapRect into the Map() but I am unable to display two MKPointAnnotation there. Also my route between these annotation is not showing It is requiring me to provide an RandomAccessCollection and a (Identifiable) -> MapAnnotationProtocol> but I do not know what to put there. Any idea what should I put in (Identifiable) -> MapAnnotationProtocol ? import SwiftUI
