Speed up route preparation for long routes 
Long routes took minutes to prepare (or appeared stuck) because of three
compounding costs, each now fixed:

- Overpass fetch: the query covered the route's whole bounding box, so a
  long or diagonal route pulled every speed-limited road in a huge
  rectangle. Replace it with an 'around' corridor query over a
  downsampled route line (75 m spacing, capped at 700 points), so the
  payload scales with route length, not bounding area. POST the query
  (corridor strings outgrow GET URLs) with an explicit 30 s timeout so a
  slow server can no longer stall route prep indefinitely — failures
  fall back to profile/ETA pacing as before.

- Speed-limit matching: nearestSpeedLimit rescanned every OSM way
  segment for every route segment (O(route x ways), tens of millions of
  distance checks on long routes). Add RouteSpeedIndex, a grid-bucketed
  spatial index (~440 m cells) probed via its 3x3 neighborhood; every
  search radius is well below one cell, so results are unchanged. The
  bus-stop approach check and the dwell snapping pass (previously
  O(stops x samples)) use the same bucketing.

- Route densification: 10 m sampling made a 300 km route produce 30k+
  points on the main thread. Sampling now widens adaptively past a 25k
  point cap; playback interpolates per tick within segments anyway, so
  smoothness is unaffected.

StikDebug

An on-device debugger/JIT enabler for iOS versions 17.4+ powered by idevice.


Features

  • JIT: Enable Just In Time compilation for sideloaded apps that have the get-task-allow entitlement.
  • App Launching: Launch every app installed on your device.
  • Console: Live app and system logs.
  • Scripts: Manage automation scripts (mainly used for iOS 26 JIT).
  • App Expiry: See when apps will expire and install/remove profiles.
  • Device Info: View detailed device metadata.
  • Processes: Inspect running apps/processes and terminate them.
  • Location Simulator: Simulate the GPS location of your device.

Download

Note

Notice: StikDebug is no longer available on the App Store. Please use the official download methods below.

Compatibility

iOS Version Status Notes
1.0 – 17.3.X Not supported Uses Different Connection Protocols
17.4 – 18.x Fully supported Stable
26.0+ Supported Limited App Availability (Developers need to update their apps to work.)

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

  2. Set up VPN

    • Launch LocalDevVPN and enable the VPN.

  3. Enable JIT for an app

    • Launch StikDebug and tapp 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 errors → Ensure that the VPN is on and that you are connecected to Wi-Fi. It may be a pairing file issue.
  • Pairing file issues → Replace file with device unlocked & trusted.
  • Still stuck? Join the Discord with logs/screenshots.

Building from Source

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.).
