Just convert it to a date using NSDateFormatter and the “h:mm a” format and convert it back to a string using the “HH:mm” format. Check out this date formatting guide to familiarize yourself with this material. let dateAsString = “6:35 PM” let dateFormatter = NSDateFormatter() dateFormatter.dateFormat = “h:mm a” dateFormatter.locale = Locale(identifier: “en_US_POSIX”) // fixes … Read more
Object Reconstruction 10 October 2023, Apple released iOS Reality Composer 1.6 app that is capable of capturing a real world model’s mesh with texture in realtime using the LiDAR scanning process. But at the moment there’s still no native programmatic API for that (but we are all looking forward to it). Also, there’s a methodology … Read more
To prevent data races you must use synchronized access to variables from concurrent operations and the compiler doesn’t allow you to change your array directly. To avoid the issue you can implement isolated access to your data with an actor instance e.g.: actor Store { var reviewIds: [Int] = [] func append(ids: [Int]) { reviewIds.append(contentsOf: … Read more
You can do this with a generic class using a where clause: A where clause enables you to require that an associated type conforms to a certain protocol, and/or that certain type parameters and associated types be the same. To use it, make the class your property is defined in a generic class with a … Read more
You can see that the contents of the array are dictionaries with String keys and unknown values. Therefore declare the array more specific var inputsOutputs = [[String:AnyObject]]() In Swift 3 for JSON collection types or if the dictionary / array contains only value types use var inputsOutputs = [[String:Any]]()
This message appears if a continuation you created via withCheckedContinuation, or withCheckedThrowingContinuation doesn’t report success or failure before being discarded. This is will lead to resource leaking: Resuming from a continuation more than once is undefined behavior. Never resuming leaves the task in a suspended state indefinitely, and leaks any associated resources. CheckedContinuation logs a … Read more
The only difference between them is that NSRange(location: 0, length: 5) is an initializer for NSRange while NSMakeRange(0, 5) is a function which creates a new NSRange instance (by using the same initializer inside most likely) and actually is redundant in Swift. Swift has simply inherited it from Objective-C. I would stick to the former
This is just how protocols currently dispatch methods. A protocol witness table (see this WWDC talk for more info) is used in order to dynamically dispatch to implementations of protocol requirements upon being called on a protocol-typed instance. All it is, is really just a listing of the function implementations to call for each requirement … Read more
You have to limit the frame size of the out-of-bounds Image before it is being picked up by the ZStack to avoid the ZStack to grow and so the Overlay to go out of position. edit: aheze shows with his answer a way around using GeometryReader by putting the Image into the background of Overlay() … Read more
Why Xcode Yelling? Maybe the message text seems a little bit self-explanatory but because Xcode does not precisely point to the parameter itself, a little bit hard to figure out the first time. Xcode is yelling because the method wants to see exact parameter types on the method call, that is easy. Solution for the … Read more
