Swift Wish List

Features I would like to see from Swift and its core ecosystem, to make it a robust and ergonomic language for all use cases.

• ❌ = Unimplemented
• 📜 = Manifesto
• ⚾️ = Pitch
• 💍 = Proposal
• ⛔️ = Partially Implemented / Awaiting Implementation
• ⚠️ = In Active Review

Catfish-Man

As of iOS 11/macOS High Sierra, and only including ones in Foundation and CoreFoundation

Strings:

_NSCFString - a CFStringRef or CFMutableStringRef. This is the most common type of string object currently.
    - May have 8 bit (ASCII) or 16 bit (UTF-16) backing store
_NSCFConstantString - a compile time constant CFStringRef, like you'd get with @"foo"
    - May also be generated by dynamic string creation if matches a string in a pre-baked table of common strings called the StringROM
NSBigMutableString - an NSString backed by a CFStorage (https://github.com/opensource-apple/CF/blob/master/CFStorage.h) for faster handling of very large strings
NSCheapMutableString - a very limited NSMutableString that allows for zero-copy initialization. Used in NSFileManager for temporarily wrapping stack buffers.

It's possible to use create an MCP installation for versions of Minecraft where there hasn't been a full MCP release. It takes a little bit of manual setup, but the end result is highly useful.

1. Download and extract the most recent MCP build from http://www.modcoderpack.com/. (Currently, the latest build is http://www.modcoderpack.com/files/mcp940.zip)

2. Edit version.cfg in the conf folder, and change ClientVersion and ServerVersion to the version you want (for instance, 1.12.2).

3. Download the SRG zip for the version you want; these can generally be found at http://mcpbot.bspk.rs/mcp/<version>/mcp-<version>-srg.zip (for example, http://mcpbot.bspk.rs/mcp/1.11.2/mcp-1.11.2-srg.zip) or at http://files.minecraftforge.net/maven/de/oceanlabs/mcp/mcp/<version>/mcp-<version>-srg.zip (for example, http://files.minecraftforge.net/maven/de/oceanlabs/mcp/mcp/1.12.2/mcp-1.12.2-srg.zip). (For 1.12.1 and 1.12.2, only the minecraftforge link works)

4. Extract that zip into the MCP conf folder, over

Exporting (iCloud) Keychain and Safari credentials to a CSV file

Update (October 2021)

Exporting password + one-time code data from iCloud Keychain is now officially supported in macOS Monterey and Safari 15 (for Monterey, Big Sur, and Catalina). You can access it in the Password Manager’s “gear” icon (System Preferences > Passwords on Monterey, and Safari > Passwords everywhere else), or via the File > Export > Passwords... menu item). You shouldn't need to hack up your own exporter anymore.

Original, Obsolete Content (2014)

After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.
