Another day, another Xcode beta.
IDE & Playgrounds
- You can now set Swift Error breakpoints, including restricting the breakpoint to specific error types.
- The in-playground API has been revamped.
XCPlaygroundPage.currentPagenow grants a reference to the current page.
- The playground live view support has been . . .
If you thought Apple was slowing down with Swift, think again. Xcode 7.1 Beta 2 includes Swift 2.1. As always you can check the release notes for yourself because I don't necessarily address everything here.
Interop & Types
- Enums imported from C automatically conform to
Equatableso now they work in pattern . . .
Some highlights from Beta 6:
Compiler & Tools
- A new
try?keyword has been added. This attempts an operation that may throw (fail). If it succeeds the result is wrapped in an optional. If it fails the error is ignored and
nilis returned. This seems like a pragmatic compromise but I have to imagine someone lost a . . .
Way too meta
What about Swift? If you've looked closely at the Swift Language Reference you'll see two short paragraphs describing
SomeClass.Type, a short example (that doesn't address
Type at all), and that's it.
In Swift, all . . .
Here is a quick rundown of some of the changes in Beta 5 posted today. For the full details as always check out the release notes
- Structs and classes can conform to
- Non-failable initializers can now chain to failable initializers by using
- Debug builds should have better performance due to using . . .
Mirror struct now has a
children property that you can indeed iterate over so this isn't really applicable anymore but the sequence stuff is still relevant. You can check out Rob Napier's post about AnySequence for more info.
I've been playing with the new reflection API in Swift 2 and found one constant . . .
Single Instruction, Multiple Awesome
Swift 2 brings updated support for SIMD (Single Instruction Multiple Data). What exactly does that mean?
Each CPU vendor has their own unique snowflake versionº but the premise is the same: process data in parallel chunks. Each SIMD instruction operates on a group of values organized into what are . . .
