xcodebuild failed with code 65

Why this happens

• Testing on a real device without a valid signing team (`xcodeOrgId`) and signing identity (`xcodeSigningId`) set
• WebDriverAgent's bundle ID clashes with one already registered to another Apple team
• The device isn't trusted, Developer Mode is turned off, or the provisioning profile has expired
• Xcode was updated and the WebDriverAgent build cache is stale

How to fix it

1. Set `appium:xcodeOrgId`, `appium:xcodeSigningId` (usually `Apple Development`), and a unique `appium:updatedWDABundleId`
2. Open WebDriverAgent.xcodeproj in Xcode once, pick your team, and build it to the device manually. Xcode's error message is far clearer than Appium's
3. Enable Developer Mode on the device and trust the developer certificate under Settings > General > VPN & Device Management
4. Clear Xcode's DerivedData after an Xcode upgrade

Example

              {
  "platformName": "iOS",
  "appium:automationName": "XCUITest",
  "appium:udid": "<device-udid>",
  "appium:xcodeOrgId": "<TEAM_ID>",
  "appium:xcodeSigningId": "Apple Development",
  "appium:updatedWDABundleId": "com.yourcompany.WebDriverAgentRunner"
