Apple has disabled WebKit's JIT in Lockdown Mode, impacting JavaScript performance. Lockdown Mode is described as extreme protection for targeted individuals, blocking complex web technologies like JavaScriptCore's JIT interpreter. This move aligns with Apple's compliance efforts with the EU's DMA, allowing third-party browser engines while maintaining security. BrowserEngineKit was developed for this purpose, enabling JIT compilation in a secure manner. Apple's decision to use BrowserEngineKit reflects a balance between performance and security, requiring authorized developers to meet specific criteria for implementing alternative browser engines. While this approach adds complexity, it aims to enhance user safety online. The choice to create BrowserEngineKit demonstrates Apple's commitment to security in the face of the EU mandate for third-party browser engines.
