![]() But without fixing that, we could still make straightforward additive changes to the compiler, standard library, and Foundation. That's a higher-level problem with the APIs that I can't speak to. Use the self-check below to refresh your memory about problem framing and to check your assumptions. Java utility methods Learn how Modelio can automatically generate Java utility methods and keep them up-to-date when the model is modified. These steps depend a lot on how you’ve framed your ML problem. Find out how Modelio can reverse Java code to build a UML architectural view, and how Modelio can improve existing Javadocs by inserting browsable UML architecture diagrams. The basic problem with your example is that Foundation.Data has erased all your element types. To construct your dataset (and before doing data transformation), you should: Collect the raw data. ![]() Pointers to uninhabited types, OpaquePointer (no bug?).Allow comparison of raw and typed pointers (no bug filed).API for "load from contiguous as: T" (no bug yet).Provide a RawPointer version of ManagedBuffer.Add a closure taking API: UnsafeRawPointer.withMemoryRebound(to:).Add UnsafePointer API that applies the field's offset.Add withUnsafeElements(to: variable) where variable is any homogenous aggregate.Support withMemoryRebound(to:) with mismatched sizes.Add an UnsafeRawPointer API for loading and storing unaligned/packed data.Don't require & to pass value to UnsafeRawPointer.Support limited implicit pointer conversion when calling C functions.Here's a list of what can be fixed immediately, roughly in decreasing priority: I think fixing those issues should have a fairly high priority. Memory Binding APIs: If you need to use bindMemory or assumingMemoryBound to work with regular memory that just holds one type, then that's a major usability bug. ![]() So, yeah it's painful, but not nearly as painful as it should be. Swift's goal is absolutely to stop people from doing this. Type-casting pointers: Whether you're doing this in C or Swift, there are some serious pitfalls that most programmers are blissfully unaware of because their code will run fine, until one day when it doesn't. Much better compiler diagnostics with educational notes that point programmers directly to that guide, particularly when they unnecessarily use a "memory binding" API. I want to have:Ī basic Swift pointer programming guide that steers programmers away from casting pointers and toward proper use of the UnsafeRawPointer API.
