This document describes the operating system versions, development platforms, UI frameworks, and third-party library compatibility supported by the iOS RUM SDK.

​
System Requirements

Flashduty RUM iOS SDK supports the following operating system versions:

​
Development Toolchain

​
Xcode

The SDK is built with the latest version of Xcode but is always backward compatible with the minimum supported Xcode version required for App Store submission.
Recommended Version: Xcode 14.0 and above

​
Dependency Management Tools

​
Programming Languages

​
Framework Compatibility

UIKit apps can be fully auto-tracked, SwiftUI apps require adding modifiers.
URLSession is recommended for fully automatic network request tracking.
UIWebView has been deprecated by Apple, please use WKWebView.

​
SDK Modules

Flashduty iOS SDK consists of the following modules:
Selectively integrate modules based on your needs. Only FlashcatCore and FlashcatRUM are required.

​
Third-party Dependencies

Flashduty iOS SDK depends on the following third-party libraries:

​
Known Limitations

  • SwiftUI views require manually adding .trackRUMView() modifier to be tracked
  • Using .trackRUMTapAction() inside List may affect default gesture behavior
  • For List elements, recommend using custom action API
SwiftUI apps are recommended to combine auto tracking and manual tracking for best monitoring results.
Unofficial Support Platforms:
  • macOS and visionOS are not officially supported platforms
  • Some features that depend on UIKit may not work properly on these platforms
  • Future version compatibility is not guaranteed
  • Catalyst mode only supports building, some runtime features may be limited
  • Recommend thorough testing before actual use
If your app primarily targets macOS Catalyst, recommend verifying all features in a test environment first.

​
Minimum Deployment Requirements

Requirements:
  • Minimum OS version: iOS 12.0 / iPadOS 12.0 / tvOS 12.0
  • Minimum Xcode version: Xcode 14.0
  • Minimum Swift version: Swift 5.0
  • Network permission: App needs network access permission to report data
  • Storage space: SDK needs small amount of local storage for caching offline data

​
Performance Impact

Flashduty iOS SDK is designed to be lightweight with minimal impact on app performance:
The SDK uses asynchronous batch processing and does not block the main thread, with minimal impact on user experience.

​
Version Update Strategy

The SDK follows Semantic Versioning:
We recommend regularly updating the SDK to the latest stable version for best performance and security.
