Extension to a generic class in Swift, where the generic parameter is also generic
It’s easier to explain the problem on an example. For instance, consider this simple generic class:
Conformance to generic constraint seems impossible with subclass
I’ve cut my code down to the following simplest version to show the problem. I’m not sure why Swift is complaining.
Cannot convert value of type ‘Container’ to expected argument type ‘Container’
Container is a generic class that accepts UIView type. VideoContainer and TitleContainer inherit Container respectively. I want to add titleContainer to the subContainer array of VideoContainer, but an error is reported.
Why would Generic Type return something other than the none generic type?
extension Data { //generic method func value<T>(from byteOffset: Int, as: T) -> T { self.withUnsafeBytes { $0.load(fromByteOffset: byteOffset, as: T.self) } } //none-generic method func uint16Value(from byteOffset: Int) -> UInt16 { self.withUnsafeBytes { $0.load(fromByteOffset: byteOffset, as: UInt16.self) } } } When I output the following: let a = data.withUnsafeBytes { $0.load(fromByteOffset: 0, as: UInt16.self) } […]
Swift Generic vs Non-Generic Function Call Precedence
Here is my code:
Make a Swift generic method take optional or unwrapped associated types
I have the following code that basically converts strings to Enums where applicable:
Embrace Swift generics question, someany keywoard. Protocol associatedtype with func
In wwdc2022 apple used static func to create model, which used later in type(of: )..
Create interface with generic types
I’m trying to create public interface for my class operating on generics.
