-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work

-![docs.rs](https://img.shields.io/docsrs/swift-rs?color=blue&style=flat-square)
-
-Call Swift functions from Rust with ease!
-
-## Setup
-
-Add `swift-rs` to your project's `dependencies` and `build-dependencies`:
-
-```toml
-[dependencies]
-swift-rs = "1.0.5"
-
-[build-dependencies]
-swift-rs = { version = "1.0.5", features = ["build"] }
-```
-
-Next, some setup work must be done:
-
-1. Ensure your swift code is organized into a Swift Package.
-This can be done in XCode by selecting File -> New -> Project -> Multiplatform -> Swift Package and importing your existing code.
-2. Add `SwiftRs` as a dependency to your Swift package and make the build type `.static`.
-```swift
-let package = Package(
-    dependencies: [
-        .package(url: "https://github.com/Brendonovich/swift-rs", from: "1.0.5")
-    ],
-    products: [
-        .library(
-            type: .static,
-        ),
-    ],
-    targets: [
-        .target(
-            // Must specify swift-rs as a dependency of your target
-            dependencies: [
-                .product(
-                    name: "SwiftRs",
-                    package: "swift-rs"
-                )
-            ],
-        )
-    ]
-)
-```
-3. Create a `build.rs` file in your project's root folder, if you don't have one already.
-4. Use `SwiftLinker` in your `build.rs` file to link both the Swift runtime and your Swift package.
-The package name should be the same as is specified in your `Package.swift` file,
-and the path should point to your Swift project's root folder relative to your crate's root folder.
-
-```rust
-use swift_rs::SwiftLinker;
-
-fn build() {
-    // swift-rs has a minimum of macOS 10.13
-    // Ensure the same minimum supported macOS version is specified as in your `Package.swift` file.
-    SwiftLinker::new("10.13")
-        // Only if you are also targetting iOS
-        // Ensure the same minimum supported iOS version is specified as in your `Package.swift` file
-        .with_ios("11")
-        .with_package(PACKAGE_NAME, PACKAGE_PATH)
-        .link();
-
-    // Other build steps
-}
-```
-
-With those steps completed, you should be ready to start using Swift code from Rust!
-
-If you experience the error `dyld[16008]: Library not loaded: @rpath/libswiftCore.dylib`
-when using `swift-rs` with [Tauri](https://tauri.app) ensure you have set your
-[Tauri minimum system version](https://tauri.app/v1/guides/building/macos#setting-a-minimum-system-version)
-to `10.15` or higher in your `tauri.config.json`. 
-
-## Calling basic functions
-
-To allow calling a Swift function from Rust, it must follow some rules:
-
-1. It must be global
-2. It must be annotated with `@_cdecl`, so that it is callable from C
-3. It must only use types that can be represented in Objective-C,
-so only classes that derive `NSObject`, as well as scalars such as Int and Bool.
-This excludes strings, arrays, generics (though all of these can be sent with workarounds)
-and structs (which are strictly forbidden).
-
-For this example we will use a function that simply squares a number:
-
-```swift
-public func squareNumber(number: Int) -> Int {
-	return number * number
-}
-```
-
-So far, this function meets requirements 1 and 3: it is global and public, and only uses the Int type, which is Objective-C compatible.
-However, it is not annotated with `@_cdecl`.
-To fix this, we must call `@_cdecl` before the function's declaration and specify the name that the function is exposed to Rust with as its only argument.
-To keep with Rust's naming conventions, we will export this function in snake case as `square_number`.
-
-```swift
-@_cdecl("square_number")
-public func squareNumber(number: Int) -> Int {
-    return number * number
-}
-```
-
-Now that `squareNumber` is properly exposed to Rust, we can start interfacing with it.
-This can be done using the `swift!` macro, with the `Int` type helping to provide a similar function signature:
-
-```rust
-use swift_rs::swift;
-
-swift!(fn square_number(number: Int) -> Int);
-```
-
-Lastly, you can call the function from regular Rust functions.
-Note that <b>all</b> calls to a Swift function are unsafe,
-and require wrapping in an `unsafe {}` block or `unsafe fn`.
-
-```rust
-fn main() {
-    let input: Int = 4;
-    let output = unsafe { square_number(input) };
-
-    println!("Input: {}, Squared: {}", input, output);
-    // Prints "Input: 4, Squared: 16"
-}
-```
-
-Check [the documentation](TODO) for all available helper types.
-
-## Returning objects from Swift
-
-Let's say that we want our `squareNumber` function to return not only the result, but also the original input.
-A standard way to do this in Swift would be with a struct:
-
-```swift
-struct SquareNumberResult {
-    var input: Int
-    var output: Int
-}
-```
-
-We are not allowed to do this, though, since structs cannot be represented in Objective-C.
-Instead, we must use a class that extends `NSObject`:
-
-```swift
-class SquareNumberResult: NSObject {
-    var input: Int
-    var output: Int
-
-    init(_ input: Int, _ output: Int) {
-        self.input = input;
-        self.output = output
-    }
-}
-```
-
-<sub><sup>Yes, this class could contain the squaring logic too, but that is irrelevant for this example
-
-An instance of this class can then be returned from `squareNumber`:
-
-```swift
-@_cdecl("square_number")
-public func squareNumber(input: Int) -> SquareNumberResult {
-    let output = input * input
-    return SquareNumberResult(input, output)
-}
-```
-
-As you can see, returning an `NSObject` from Swift isn't too difficult.
-The same can't be said for the Rust implementation, though.
-`squareNumber` doesn't actually return a struct containing `input` and `output`,
-but instead a pointer to a `SquareNumberResult` stored somewhere in memory.
-Additionally, this value contains more data than just `input` and `output`:
-Since it is an `NSObject`, it contains extra data that must be accounted for when using it in Rust.
-
-This may sound daunting, but it's not actually a problem thanks to `SRObject<T>`.
-This type manages the pointer internally, and takes a generic argument for a struct that we can access the data through.
-Let's see how we'd implement `SquareNumberResult` in Rust:
-
-```rust
-use swift_rs::{swift, Int, SRObject};
-
-// Any struct that is used in a C function must be annotated
-// with this, and since our Swift function is exposed as a
-// C function with @_cdecl, this is necessary here
-#[repr(C)]
-// Struct matches the class declaration in Swift
-struct SquareNumberResult {
-    input: Int,
-    output: Int 
-}
-
-// SRObject abstracts away the underlying pointer and will automatically deref to
-// &SquareNumberResult through the Deref trait
-swift!(fn square_number(input: Int) -> SRObject<SquareNumberResult>);
-```
-
-Then, using the new return value is just like using `SquareNumberResult` directly:
-
-```rust
-fn main() {
-    let input = 4;
-    let result = unsafe { square_number(input) };
-
-    let result_input = result.input; // 4
-    let result_output = result.output; // 16
-}
-```
-
-Creating objects in Rust and then passing them to Swift is not supported.
-
-## Optionals
-
-`swift-rs` also supports Swift's `nil` type, but only for functions that return optional `NSObject`s.
-Functions returning optional primitives cannot be represented in Objective C, and thus are not supported.
-
-Let's say we have a function returning an optional `SRString`:
-
-```swift
-@_cdecl("optional_string")
-func optionalString(returnNil: Bool) -> SRString? {
-    if (returnNil) return nil
-    else return SRString("lorem ipsum")
-}
-```
-
-Thanks to Rust's [null pointer optimisation](https://doc.rust-lang.org/std/option/index.html#representation),
-the optional nature of `SRString?` can be represented by wrapping `SRString` in Rust's `Option<T>` type!
-
-```rust
-use swift_rs::{swift, Bool, SRString};
-
-swift!(optional_string(return_nil: Bool) -> Option<SRString>)
-```
-
-Null pointers are actually the reason why a function that returns an optional primitive cannot be represented in C.
-If this were to be supported, how could a `nil` be differentiated from a number? It can't!
-
-## Complex types
-
-So far we have only looked at using primitive types and structs/classes,
-but this leaves out some of the most important data structures: arrays (`SRArray<T>`) and strings (`SRString`).
-These types must be treated with caution, however, and are not as flexible as their native Swift & Rust counterparts.
-
-### Strings
-
-Strings can be passed between Rust and Swift through `SRString`, which can be created from native strings in either language.
-
-**As an argument**
-
-```swift
-import SwiftRs
-
-@_cdecl("swift_print")
-public func swiftPrint(value: SRString) {
-    // .to_string() converts the SRString to a Swift String
-    print(value.to_string())
-}
-```
-
-```rust
-use swift_rs::{swift, SRString, SwiftRef};
-
-swift!(fn swift_print(value: &SRString));
-
-fn main() {
-    // SRString can be created by simply calling .into() on any string reference.
-    // This will allocate memory in Swift and copy the string
-    let value: SRString = "lorem ipsum".into();
-
-    unsafe { swift_print(&value) }; // Will print "lorem ipsum" to the console
-}
-```
-
-**As a return value**
-
-```swift
-import SwiftRs
-
-@_cdecl("get_string")
-public func getString() -> SRString {
-    let value = "lorem ipsum"
-
-    // SRString can be created from a regular String
-    return SRString(value)
-}
-```
-
-```rust
-use swift_rs::{swift, SRString};
-
-swift!(fn get_string() -> SRString);
-
-fn main() {
-    let value_srstring = unsafe { get_string() };
-
-    // SRString can be converted to an &str using as_str()...
-    let value_str: &str = value_srstring.as_str();
-    // or though the Deref trait
-    let value_str: &str = &*value_srstring;
-
-    // SRString also implements Display
-    println!("{}", value_srstring); // Will print "lorem ipsum" to the console
-}
-```
-
-### Arrays
-
-**Primitive Arrays**
-
-Representing arrays properly is tricky, since we cannot use generics as Swift arguments or return values according to rule 3.
-Instead, `swift-rs` provides a generic `SRArray<T>` that can be embedded inside another class that extends `NSObject` that is not generic,
-but is restricted to a single element type.
-
-```swift
-import SwiftRs
-
-// Argument/Return values can contain generic types, but cannot be generic themselves.
-// This includes extending generic types.
-class IntArray: NSObject {
-    var data: SRArray<Int>
-
-    init(_ data: [Int]) {
-        self.data = SRArray(data)
-    }
-}
-
-@_cdecl("get_numbers")
-public func getNumbers() -> IntArray {
-    let numbers = [1, 2, 3, 4]
-
-    return IntArray(numbers)
-}
-```
-
-```rust
-use swift_rs::{Int, SRArray, SRObject};
-
-#[repr(C)]
-struct IntArray {
-    data: SRArray<Int>
-}
-
-// Since IntArray extends NSObject in its Swift implementation,
-// it must be wrapped in SRObject on the Rust side
-swift!(fn get_numbers() -> SRObject<IntArray>);
-
-fn main() {
-    let numbers = unsafe { get_numbers() };
-
-    // SRArray can be accessed as a slice via as_slice
-    let numbers_slice: &[Int] = numbers.data.as_slice();
-
-    assert_eq!(numbers_slice, &[1, 2, 3, 4]);
-}
-```
-
-To simplify things on the rust side, we can actually do away with the `IntArray` struct.
-Since `IntArray` only has one field, its memory layout is identical to that of `SRArray<usize>`,
-so our Rust implementation can be simplified at the cost of equivalence with our Swift code:
-
-```rust
-// We still need to wrap the array in SRObject since
-// the wrapper class in Swift is an NSObject
-swift!(fn get_numbers() -> SRObject<SRArray<Int>>);
-```
-
-**NSObject Arrays**
-
-What if we want to return an `NSObject` array? There are two options on the Swift side:
-
-1. Continue using `SRArray` and a custom wrapper type, or
-2. Use `SRObjectArray`, a wrapper type provided by `swift-rs` that accepts any `NSObject` as its elements.
-This can be easier than continuing to create wrapper types, but sacrifices some type safety.
-
-There is also `SRObjectArray<T>` for Rust, which is compatible with any single-element Swift wrapper type (and of course `SRObjectArray` in Swift),
-and automatically wraps its elements in `SRObject<T>`, so there's very little reason to not use it unless you _really_ like custom wrapper types.
-
-Using `SRObjectArray` in both Swift and Rust with a basic custom class/struct can be done like this:
-
-```swift
-import SwiftRs
-
-class IntTuple: NSObject {
-    var item1: Int
-    var item2: Int
-
-    init(_ item1: Int, _ item2: Int) {
-       self.item1 = item1
-       self.item2 = item2
-    }
-}
-
-@_cdecl("get_tuples")
-public func getTuples() -> SRObjectArray {
-    let tuple1 = IntTuple(0,1),
-        tuple2 = IntTuple(2,3),
-        tuple3 = IntTuple(4,5)
-
-    let tupleArray: [IntTuple] = [
-        tuple1,
-        tuple2,
-        tuple3
-    ]
-
-    // Type safety is only lost when the Swift array is converted to an SRObjectArray
-    return SRObjectArray(tupleArray)
-}
-```
-
-```rust
-use swift_rs::{swift, Int, SRObjectArray};
-
-#[repr(C)]
-struct IntTuple {
-    item1: Int,
-    item2: Int
-}
-
-// No need to wrap IntTuple in SRObject<T> since
-// SRObjectArray<T> does it automatically
-swift!(fn get_tuples() -> SRObjectArray<IntTuple>);
-
-fn main() {
-    let tuples = unsafe { get_tuples() };
-
-    for tuple in tuples.as_slice() {
-        // Will print each tuple's contents to the console
-        println!("Item 1: {}, Item 2: {}", tuple.item1, tuple.item2);
-    }
-}
-```
-
-Complex types can contain whatever combination of primitives and `SRObject<T>` you like, just remember to follow the 3 rules!
-
-## Bonuses
-
-### SRData
-
-A wrapper type for `SRArray<T>` designed for storing `u8`s - essentially just a byte buffer.
-
-### Tighter Memory Control with `autoreleasepool!`
-
-If you've come to Swift from an Objective-C background, you likely know the utility of `@autoreleasepool` blocks.
-`swift-rs` has your back on this too, just wrap your block of code with a `autoreleasepool!`, and that block of code now executes with its own autorelease pool!
-
-```rust
-use swift_rs::autoreleasepool;
-
-for _ in 0..10000 {
-    autoreleasepool!({
-        // do some memory intensive thing here
-    });
-}
-```
-
-## Limitations
-
-Currently, the only types that can be created from Rust are number types, boolean, `SRString`, and `SRData`.
-This is because those types are easy to allocate memory for, either on the stack or on the heap via calling out to swift,
-whereas other types are not. This may be implemented in the future, though.
-
-Mutating values across Swift and Rust is not currently an aim for this library, it is purely for providing arguments and returning values.
-Besides, this would go against Rust's programming model, potentially allowing for multiple shared references to a value instead of interior mutability via something like a Mutex.
