License

The licensing of these crates is a bit complicated:

• The crates objc2, block2, objc2-foundation and objc2-encode are currently licensed under the MIT license.
• All other crates are trio-licensed under the Zlib, Apache-2.0 or MIT license, at your option.

Furthermore, the crates are (usually automatically) derived from Apple SDKs, and that may have implications for licensing, see below for details.

Apple SDKs

These crates are derived from Apple SDKs shipped with Xcode. You can obtain a copy of the Xcode license at:

https://www.apple.com/legal/sla/docs/xcode.pdf

Or by typing xcodebuild -license in your terminal.

From reading the license, it is unclear whether distributing derived works such as these crates are allowed?

But in any case, to practically use these crates, you will have to link, and that only works when you have the correct Xcode SDK available to provide the required .tbd files, which is why we choose to still use the normal SPDX identifiers in the crates (Xcode is required to use the crates, and when using Xcode you have already agreed to the Xcode license).
