Two Years of Switch Emulation on iPhone: From Apple's Emulator Rules to the iOS 26 JIT Problem (2024–2026)

As of November 2026, you can run a Switch emulator on iPhone and iPad, but only by sideloading it and enabling JIT separately. Apple opened the App Store to emulators in April 2024, but App Store apps still can't use JIT, so Switch-class emulators that need just-in-time compilation have never gotten in. iOS 26 then added TXM, which broke the old ways of turning JIT on. Here's how the last two years played out.

Why it all comes down to JIT

A Switch emulator translates the game's ARM machine code into native code while it runs. That's JIT, just-in-time compilation. iOS blocks normal apps from creating executable memory unless a debugger is attached. Apps from the App Store and TestFlight can't get that permission, which is why MeloNX's documentation says flatly that it won't run without JIT.

Timeline

iOS 26 and TXM: back to square one

The day after WWDC 2025, LiveContainer developer Duy Tran said Apple had effectively killed JIT in iOS 26. The reason was TXM (Trusted Execution Monitor) on A15/M2 and newer chips: a memory page an app writes code into must first be written by a debugger before it can execute.

The community found a way through. StikDebug acts as the debugger and runs a script (the general-purpose universal.js) that prepares executable regions when the app launches. But the emulator has to change how it allocates memory, so on iOS 26 only apps their developers have adapted can get JIT. Quit the app fully and you have to authorize it again. SideStore's documentation says iOS 26 broke JIT once again and that only a handful of apps work on 26.6 and 27. MeloNX is on that list.

StikDebug: on the App Store, off again, still sideloaded

StikDebug is an on-device debugger. After the first pairing it doesn't need a computer, but it does need a pairing file and a local loopback VPN. It briefly reached the US App Store in May 2025, and 9to5Mac suggested that could free iOS Switch emulation from the computer. In December, Apple terminated the developer's account and the app was pulled. Distribution moved to sideloading and development continued. Version 3.2.0 on October 30, 2026 can create pairing files right on the device, which could remove the computer from the process entirely. Users still need to confirm how well it works.

Alternative app stores don't help

Users in the EU (under the Digital Markets Act) and in Japan (under its smartphone software competition law, in force since December 18, 2025) can use stores such as AltStore PAL. heise reported that the JIT ban covers apps in those stores too, so Switch emulators there still need StikDebug.

What this means for players

• For iPhone and iPad, start with MeloNX. An iPhone 15 Pro or newer is recommended; the system caps app memory at 6 GB. Follow the iPhone / iPad setup guide and enabling JIT with StikDebug.
• If you depend on JIT, don't rush iOS updates. Both 26.4 and 27.0 caused problems. Wait for StikDebug and MeloNX to confirm support.
• nxnative is a different route: each game becomes its own native app. It needs a Mac with Xcode and only supports A17 Pro / M1 or newer on iOS 26+. It isn't an emulator and works very differently.
• The iOS builds of Sudachi and Pomelo are dead, and Eden has no working iOS version, so treat any "Eden iOS download" with suspicion. More on the iOS platform page.
