## Why?



XCFrameworks are a new way to bundle up multiple variants of your framework in a way that will work across Xcode Versions going forward.



After Xcode 11 now Xcode fully supports using and creating binary frameworks in Swift. Simultaneously support devices and Simulator with the new XCFramework bundle type. XCFrameworks support the binary distribution of Swift and C-based code. A single XCFramework can contain a variant for the simulator, and for the device. This means you can ship slices for any of the architectures, including simulator, any Apple OS and even separate slices for UIKit and AppKit apps. 



## Requirements



- macOS Version 11.2 and above

- Xcode 12 and above

- Swift 5.1 and above



# Installing surmagic



### Xcode command line tools (macOS)



*If you've already installed the command-line tools you can skip this step.*



Install the command line tools with the command below:



```bash

$ xcode-select --install

```



### Homebrew (macOS)



[Brew](https://brew.sh) is the Recommended way to install / uninstall the surmagic.



```bash

$ brew tap gurhub/surmagic

$ brew install surmagic

```



This command will install _surmagic_ to your desired bash.



## Manually Install



Or you can download the latest binary from [this directory](https://github.com/gurhub/surmagic/blob/master/bin/surmagic). And copy under your **/usr/local/bin** directory.



# Setting up surmagic



Open the desired terminal application and enter inside of your project directory's root: 



```bash

$ cd [path-on-your-disk]/your-project

```



Use the command below to create the necessary _surmagic_ directory and files.



```bash

$ surmagic init

``` 



This will create a surmagic directory and a Surfile like below:



- --- Your-Project-Directory         

- ------ SM                     : A directory created by You or by the init command

- --------- Surfile             : A Surfile created by You or by the init command



## How To Create an XCFramework



After [setting up your directory](#setting-up-surmagic), and filling mandatory parameters in the [Surfile](#what-is-the-surfile) you can simply use:



```bash

$ surmagic xcf

```

command to create an XCFramework. That's it. There are other commands too. Please keep reading.

# All Available Commands and Options



Use 'surmagic --help' to learn all available commands in the surmagic.



```bash

USAGE: surmagic 



OPTIONS:

  --version               Show the version.

  -h, --help              Show help information.



SUBCOMMANDS:

  init                    Creates the mandatory directory (surmagic) and files.

  xcf (default)           Creates an XCFramework via Surfile.

  env                     To use while creating an issue on Github, prints the

                          user's environment.



  See 'surmagic help ' for detailed help.

```



## Passing parameters to _surmagic_ command-line tools



Surmagic contains several command-line tools, e.g. **surmagic xcf** or **surmagic init**. To pass parameters to these tools, append the option names and values as you would for a normal shell command:



```bash

$ surmagic [tool] --[option] --[option] ...∞



$ surmagic init

$ surmagic xcf --verbose

```



# What is the Surfile



The Surfile is used to configure _surmagic_. Open it in your favorite text editor, and add desired targets.



It's a standard Plist (XML) file.



The Surfile has to be inside your ./SM directory.



The Surfile stores the automation configuration that can be run with _surmagic_.



```xml



  output_path

  _OUTPUT_DIRECTORY_NAME_HERE_

  framework

  _FRAMEWORK_NAME_HERE_

  targets

  

    

      sdk

      _TARGET_OS_HERE_

      workspace

      _WORKSPACE_NAME_HERE_.xcworkspace

      scheme

      _SCHEME_NAME_HERE_

    

     

  

  finalActions

  

    openDirectory

  



```



##### SDK Options 



| Key            	| Description     	|

|----------------	|-----------------	|

| iOS            	| iOS             	|

| iOSSimulator   	| iOS Simulator   	|

| macOS          	| macOS           	|

| macOSCatalyst  	| macOS Catalyst  	|

| tvOS           	| tvOS            	|

| tvOSSimulator  	| tvOS Simulator  	|

| watchOS        	| watchOS         	|

| watchSimulator 	| watch Simulator 	|

# Further Reading



## What is an XCFramework?



An XCFramework is a distributable binary package created by Xcode that contains variants of a framework or library so that it can be used on multiple platforms (iOS, macOS, tvOS, and watchOS), including Simulator builds. An XCFramework can be either static or dynamic and can include headers.



To use a prebuilt XCFramework, link the target to the XCFramework. Xcode ensures that the target can build against the XCFramework’s headers, link against its binary, and embed it for distribution. If your app has multiple targets (such as app extensions) that use the same XCFramework, you should pick one target (usually your app’s target) to embed the XCFramework and the others should link it without embedding.



Check in the [official Apple documentation](https://help.apple.com/xcode/mac/11.4/#/dev6f6ac218b).



## What is a Swift package?



A Swift package is a folder containing a manifest file and source files used to build software products.



The package manifest (a file named Package.swift at the top level of the package folder) defines the package’s name, products, targets, and dependencies on other packages. The manifest file is written in Swift using API from the Swift Package Manager's PackageDescription library



A package product defines the externally visible build artifact, such as libraries and executables, that are available to clients of a package. A package target defines a test or module from which the products in a package are built. Targets may have dependencies on targets in the same package and dependencies on products from its package dependencies.



A package dependency enables a package target, or Xcode project, to use a product in another package. A package dependency is specified by a URL to the remote Git repository containing the package, and the versions of the package that are supported by the client. The format of a package version uses the Semantic Versioning specification, which is typically a three period-separated integer, such as 2.1.4.



The source files for targets can be written in Swift, C/C++, Objective-C/C++, or assembler, and are located under the Sources folder in the package. Each target can either contain only Swift source code, or any combination of C, C++, Objective-C, Objective-C++, and assembler source code. The source files for Test targets are written using the [XCTest](https://developer.apple.com/documentation/xctest) framework, and are located under the Tests folder.



Check in the [official Apple documentation](https://help.apple.com/xcode/mac/11.4/#/dev5eb834795).



## Advantages of the XCFramework, comparison with the FAT Framework Approach:



* Packing dependencies under all target platforms and architectures into one single bundle from the box

* Connection of the bundle in the format of XCFramework, as a single dependency for all target platforms and architectures

* Missing the need of building fat/universal framework

* No need to get rid of x86_64 slices before uploading end applications to AppStore



Also, with surmagic, you won't need to be an expert on the questions listed below:



* How to create XCFramework in Xcode?

* How to build Universal iOS Frameworks using XCFramework

* XCFramework tutorial

* How do I use XCFramework? 

* What is XCFramework?

* How do I create a custom framework in Swift? 

* How to add XCFramework to Xcode project?

* How do I import framework into Xcode?

* What is Xcode framework? 

* Convert a Universal (FAT) Framework to an XCFramework

* Advances in XCFramework

* Automatic support for Apple Silicon via FAT binaries

* Built-in support for the BCSymbolMaps and dSYMs



## Why not the Swift Package Manager (SPM)?



Well, why not!🤓 It's the easiest! But, Swift PM only allows you to perform the delivery of libs in the form of *open source* code with the description of dependencies.



Apple presented XCFramework as **a new binary format of packing the libs**, considering it as an alternative for [Swift Packages](https://swift.org/package-manager/).
