[Appium][Issue] 讓 Appium 1.2.x 支援 Xcode 6

昇級到 Xcode 6 之後，Appium (1.2.x) 在啟動 instrument 時會丟出下面的錯誤：

error: Could not find Automation.tracetemplate in /Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate

[Appium][Issue] Invalid Instruments Service (iOS)

第一次遇到 Appium 無法啟動 instruments 的問題，Appium server 吐出下面的錯誤：

Appium 1.2.0 + iPod touch (iOS 7.1)

debug: [INST STDERR] 2014-08-06 16:23:36.456 instruments[24518:1a03] Failed to start Instruments daemon for 'iOS' on '...' (The service is invalid.)
