### iOS Simulator (arm64 + x86_64) Architecture Details

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/framework-structure.md

Details for the iOS simulator binary, which is a universal binary containing both x86_64 and arm64 architectures.

```text
Universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64:Mach-O 64-bit dynamically linked shared library arm64]
```

--------------------------------

### Objective-C: Import WebRTC and Initialize Factory

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/installation-guide.md

Import the WebRTC framework in your Objective-C code and initialize the RTCPeerConnectionFactory for creating peer connections.

```objectivec
@import WebRTC;

@interface VideoCallViewController : UIViewController
@property (nonatomic, strong) RTCPeerConnection *peerConnection;
@end

@implementation VideoCallViewController
- (void)setupPeerConnection {
    RTCPeerConnectionFactory *factory = [[RTCPeerConnectionFactory alloc] init];
    // Use factory to create connections
}
@end
```

--------------------------------

### Check WebRTC Framework Architecture Slices

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Verifies that the WebRTC.xcframework includes the necessary architecture slices for both physical devices (e.g., `ios-arm64`) and simulators (e.g., `ios-x86_64_arm64-simulator`). This is important for apps that build on the simulator but crash on a device.

```bash
ls WebRTC.xcframework/
# Should contain: ios-arm64/ (device)
#                ios-x86_64_arm64-simulator/ (simulator)
```

--------------------------------

### Conditional WebRTC Initialization for Previews

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

This Swift code demonstrates how to conditionally initialize WebRTC only when the application is running, not during SwiftUI Previews. This prevents 'Unable to instantiate RTCPeerConnectionFactory' errors in previews.

```swift
#if DEBUG
// Only initialize WebRTC in actual app, not preview
@main
struct MyApp: App {
    @State var callManager: CallManager?
    
    init() {
        #if !PREVIEW_MODE
        self.callManager = CallManager()
        #endif
    }
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}
#endif
```

--------------------------------

### Clean and Build Project

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Perform a clean build after resetting caches to ensure a fresh project state.

```Xcode
Cmd+Shift+K (Clean)
Cmd+B (Build)
```

--------------------------------

### Objective-C Usage of WebRTC

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/framework-structure.md

```objc
@import WebRTC;
// or
#import <WebRTC/WebRTC.h>

RTCPeerConnectionFactory *factory = [[RTCPeerConnectionFactory alloc] init];
```

--------------------------------

### Add Carthage Build Phase in Xcode

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/installation-guide.md

Configure your Xcode project to include the WebRTC framework. This can be done via the 'Frameworks, Libraries, and Embedded Content' section or a 'Copy Files' build phase.

```bash
/usr/local/bin/carthage copy-frameworks

# Input files
$(SRCROOT)/Carthage/Build/WebRTC.xcframework

# Output files
$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/WebRTC.xcframework
```

--------------------------------

### Check Disk Space

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Verify available disk space on the root partition, ensuring at least 5GB is free for builds and archives.

```bash
df -h /
# Ensure at least 5GB free
```

--------------------------------

### CocoaPods: Development from Source

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/installation-guide.md

For testing or development purposes, specify the 'WebRTC-lib' pod to be fetched directly from its Git repository and branch.

```ruby
pod 'WebRTC-lib', :git => 'https://github.com/stasel/WebRTC.git', :branch => 'latest'
```

--------------------------------

### Verify xcframework Architecture

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/platform-support.md

Use `xcframework info` to check if the WebRTC xcframework includes the necessary architecture slices, particularly for Apple Silicon compatibility.

```bash
xcframework info WebRTC.xcframework
```

--------------------------------

### Check Binary Architecture

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/platform-support.md

Use `lipo -info` to inspect the architecture information of a binary, useful for diagnosing issues related to architecture mismatches.

```bash
lipo -info WebRTC.framework/WebRTC
```

--------------------------------

### Verify WebRTC Framework Architecture Compatibility

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Check if the WebRTC framework contains the necessary architectures for the target platform (simulator or device). This helps diagnose 'dyld: Symbol not found' errors.

```bash
# For simulator, verify xcframework contains architectures:
file Pods/WebRTC-lib/WebRTC.xcframework/ios-*/WebRTC.framework/WebRTC
# Should show: arm64, x86_64 (depending on platform)
```

--------------------------------

### Pin WebRTC Version for Legacy Projects (Swift)

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/README.md

Use `.exact()` to pin a specific version of the WebRTC package for legacy projects, ensuring stability.

```swift
.package(url: "https://github.com/stasel/WebRTC.git", .exact("140.0.0"))
```

--------------------------------

### Swift Package Manager Dependency Usage

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/package-configuration.md

// In your Package.swift dependencies:
dependencies: [
    .package(url: "https://github.com/stasel/WebRTC.git", .upToNextMajor("149.0.0"))
]

// In your target dependencies:
.target(
    name: "YourTarget",
    dependencies: ["WebRTC"])

```

--------------------------------

```

--------------------------------

### Configure SPM Deployment Target

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/platform-support.md

Ensure the `platforms` declaration in your `Package.swift` file specifies the minimum deployment version for each platform to resolve SPM issues.

```swift
platforms: [.iOS(.v12), .macOS(.v10_11)]
```

--------------------------------

### Verify Network Connectivity to Binary Repository

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Check if you can reach the remote repository hosting the binary frameworks. This helps diagnose network-related download failures.

```bash
curl -I https://raw.githubusercontent.com/stasel/WebRTC/latest/WebRTC.json
```

--------------------------------

### Correct and Incorrect Cartfile Syntax

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Ensure your Cartfile uses the correct 'binary' keyword for specifying remote binary frameworks. Incorrect syntax can lead to build failures.

```shell
# ✅ Correct
binary "https://raw.githubusercontent.com/stasel/WebRTC/latest/WebRTC.json"
```

```shell
# ❌ Incorrect (missing binary keyword)
"https://raw.githubusercontent.com/stasel/WebRTC/latest/WebRTC.json"
```

--------------------------------

### Objective-C: Import WebRTC and Initialize Factory (CocoaPods)

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/installation-guide.md

Import the WebRTC header file and initialize the RTCPeerConnectionFactory within your Objective-C class when using CocoaPods.

```objectivec
#import <WebRTC/WebRTC.h>

@interface VideoCallViewController : UIViewController
@end

@implementation VideoCallViewController
- (void)setupRTC {
    RTCPeerConnectionFactory *factory = [[RTCPeerConnectionFactory alloc] init];
}
@end
```

--------------------------------

### List Available WebRTC Releases via GitHub API

Source: https://github.com/stasel/webrtc/blob/latest/_autodocs/troubleshooting.md

Query the GitHub API to retrieve a list of all available release tag names for the WebRTC repository. This is useful for verifying version existence.

```bash
curl -s https://api.github.com/repos/stasel/WebRTC/releases | jq '.[].tag_name'
```

--------------------------------

### Add Swift Package Manager Dependency (Latest Branch)

Source: https://github.com/stasel/webrtc/blob/latest/README.md

Use this to add the WebRTC package from the 'latest' branch for the most up-to-date binary.

```swift
dependencies: [
    .package(url: "https://github.com/stasel/WebRTC.git", branch: "latest")
]
```
