[swift-users] More Swift-like initializers and enums in UIKit

I've been using `UIViewControllerAnimatedTransitioning` recently and the associated APIs are usable but decidedly not very Swifty. Lots of the main UIKit APIs got a Swift makeover as we've progressed through releases but there are still a few such as this one that could use some touching up. I

[swift-users] Failed to resolve REPL breakpoint

I have compiled from the latest Swift source and built a package for my system using the install to destination. However, after installing the package and running `swift` to test the REPL it dies with the following error: `error: failed to resolve REPL breakpoint for 'repl_main'`. Not really sure

Re: [swift-users] C/FFI interop

I think the OP was asking not about importing C symbols into Swift but rather exporting Swift to C. On Wed, 23 Dec 2015 at 15:18 Brent Royal-Gordon via swift-users < swift-users@swift.org> wrote: > > What are the current facilities planned or in development for FFI? Just > as Swift functions can

The relevant bit is in there: open("/home/dorsatum/swift/usr/lib/swift/linux/x86_64/SwiftShims.swiftmodule", O_RDONLY) = -1 ENOENT (No such file or directory) I am not sure what it should be loading but this file does not exist in the distribution so I wonder why it is searching for it. I had

[swift-users] error: value of type 'Self.SubSequence' has no member 'Distance'

I have an array of String and need to call withCString on each one and then pass the resulting array of UnsafePointer to a C api. The unsafe pointer is only valid within the scope of withCString. So I built the following, but the compiler doesn’t like it: % swift scopedReduceAndApply.swift

Option 1. Export your Swift to Obj-C. Write Obj-C that exports C. Compile to a library. Option 2. Use this syntax and swift-demangle to figure out the symbols: public var badfood:@convention(c)(Int) -> Void = { (i:Int) in print(i) } -david On 12/23/15, Thomas Catterall via swift-users

[swift-users] _swift_abortRetainUnowned when capturing @objc class as unowned

Hey, I am experiencing this strange crashing when capturing an instance of a @objc class (written in swift, but annotated with @objc and subclass of NSObject). It happens when the closure is being assigned and not when called, so the problem is not that the captured value would get deallocated

This contains a part of the strace output. The entire output is quite large ~ 7k LoC, Would that be required? On Wed, Dec 23, 2015 at 2:52 PM, Jason Dusek wrote: > It would be helpful if you provided strace output. > > On Wed, 23 Dec
