• Checked array indexing (substandard library?) https://gist.github.com/erica/5abc26762d0b9c4876ba59950417b24b

• Keypath initialization: code sample exploration

• Raw Strings

Vested Interest

• Dave's setprotocol
• Making endian a conditional compilation thing?
• Steven Celis' automatically derive properties for enum cases

Sort of Dead

• John H's Raw Mode string literals (see forum thread)
• Flexible access control scoping: proposal, branch
• Rearchitecting if/guard case: branch
• Platform configuration tests: branch
• Checked array

Quick notes:

Death to enumerated, throwing subscripts, rehydrating labels for use at call sites and closures, extending swift literals, with/rebinding self, more platform config (https://gist.github.com/erica/c9c11b540a2439696b2f514c2ffc6298), extending range operators for lhs open/closed, macros, decimal numbers, self rebinding (evan m's proposal, which is merged), result type, version numbers for canImport, de-init stacks (like defer), prebuilt stderr/stdout, stored values in extensions, better pattern matching

Newish

• guard let value = try throwingFunction() catch let error { print (error); return },
• Promises, promises, Lenses,Method cascades

Phase II

• Symbology Update. Discussions on-list.
• Removing enumerated() draft See previous: Introducing indexed() collections

Starter proposals here

Alive and Active

• Unwrap
• Unwrappable
• Index
• Boolean raw enumeration type
• Warning/Error
• Throwing subscripts

To do

• SE-????: Promoting _isDebugAssertConfiguration, _isReleaseAssertConfiguration, and _isFastAssertConfiguration Pitched 5/29
• Better optional comparison Old pitch
• Simplifying if-case/guard-case, pitched 10/24

Watch this space / Out of Scope for Swift 3

• Rehydrating Labels: Re-introducing labels for use at call sites and closures once they've been removed from the type system.
• SE-YYYY: Extending Swift Literals Pitched 7/10
• SE-YYYY Introducing with to the Standard Library: Pull request here Out of scope for Swift 3
• SE-YYYY Enhancing the Platform Configuration Test Suite for Conditional Compilation Blocks Chris L: "I think that this is a fine proposal, but will need to wait for Swift 3.x where x > 0, since it is an additive proposal. We'd like the community to stay as focused as possible on Swift 3.0 related work. Thanks!" Pull request here
• SE-YYYY: Boolean Raw Value Enumerations "@ericasadun @clattner_llvm In seriousness, extending the set of enum raw value literals to include bools seems reasonable, albeit additive. (Joe G)"

Unlikely to go far

• SE-YYYY: Extending Swift Switch Statements with Continue Pitched 7/10 Lattner: deliberately removed
• if case/guard case with ~= or :

Thoughts

• Switch expressions and if expressions vs statements.

Just for fun

• SE-M00F
• SE-0666

Back burner and On My Radar

• Len/loc operator?
• That newtype thing that's been brought up a few times.
• Possible to establish requirement external to protocol, e.g. this type can be initialized by Double?
• SE-XXXX Range Operators, ditto
• Expanding Cocoa and Cocoa Touch Defaults / Would have to go through as radar requests, not sure which ones mattter.
• Brent's string format stuff
• CoreError, NilError, DefaultError: github also, attempt?
• import as to enable modules to import with different names (primarily to disambiguate conflicts and simplify access to multi-level
• macros, Better option sets, Decimal numbers (Joe Groff/Ranier Brockerhoff)
• Method Cascades and older submitted as bug report for now
• The strong/weak dance: proposed by Evan M: optional binding to upgrade self
• Enumerated members: PR
• Result type
• Lenses: see http://twitter.com/mbrandonw/status/739538002641358848
• Version Numbers for canImport
• Swift tuples for bytes of arb length/type for c interop with = 0x0
• Graham Perks' de-init/defer: http://thread.gmane.org/gmane.comp.lang.swift.evolution/20019
• Stderr, stdout prebuilt
• Sequence with "until"/"while"
• Failable literal initializers
• Enums with stored properties (for it)
• curried argument labels and SE-0111 - is there a future way forward
• Joe Groff: array/dict (string) pattern matching
• John McCall / Manual Memory Management in Swift
• Newtype
