Caution

WARNING: There are known critical issues with iOS 26.4 Developer Beta 1. The lockdownd service appears to be dropping connections, which interferes with how the device connects to itself (loopback/pairing issues) and prevents JIT from functioning. DO NOT UPDATE if you rely on StikDebug. These issues and possible fixes are currently being investigated.

How to Enable JIT

StikDebug enables JIT for sideloaded apps on iOS 17.4+ without needing a computer after the initial pairing setup.

Requirements

• StikDebug installed (via AltSource, direct .ipa, or self-built)
• A valid pairing file (.plist / .mobiledevicepairing) for your device
• SideStore / AltStore / similar sideload tool (for app refreshing)
• A loopback vpn such as LocalDevVPN

Steps

1. Obtain a pairing file

   • Detailed guide: Pairing File Instructions (or ask in Discord).

2. Set up VPN

   • Launch LocalDevVPN and enable the vpn.

3. Enable JIT for an app

   • Launch StikDebug and press the Enable JIT button.
   • Select your sideloaded app from the list in StikDebug.

Troubleshooting

• "Connection dropped" or loopback errors → Check iOS version compatibility / beta warnings.
• Heartbeat erros → Ensure that the vpn is on and that you are connecected to Wi-Fi.
• Pairing file issues → Regenerate file with device unlocked & trusted.
• Still stuck? Join the Discord with logs/screenshots.

Building from Source

Note

StikDebug is an open-source Xcode project written mostly in Swift. Building yourself lets you modify code, debug, or create custom versions. Requires a Mac with Xcode.

Requirements

• macOS (latest recommended)
• Xcode 16+ (Xcode 26+ preferred for iOS 26+ support)
• iOS device on iOS 17.4+ (for testing)
• Git
• Basic Xcode/Swift knowledge

Steps

1. Clone the repo

   git clone https://github.com/StephenDev0/StikDebug.git
   cd StikDebug

2. Open in Xcode

   • Launch Xcode
   • Open StikDebug.xcodeproj

3. Configure signing

   • Select the StikDebug target
   • Go to Signing & Capabilities
   • Sign in with your Apple ID (free or paid developer account)
   • Set a unique Bundle Identifier (e.g., com.yourname.StikDebug)

4. Build & install

   • Select your connected device
   • Press Cmd + R (or Product → Run)
   • Trust the certificate on device: Settings → General → VPN & Device Management

After install, follow the JIT setup steps above (pairing import, etc.).
