Facing this issue while working on appium. couldnt able to launch the app in the simulator as appium server is throwing the above error. In my case I had installed appium from a different user and the owner of the Appium.app was other user than the user I was trying to run from. Changing the owner to the current user resolved the issue. I resolved this error by running ps aux | grep appium from command line, kill all appium and node processes and then restart appium. 来源： https://stackoverflow.com/questions/22248328/a-new-session-could-not-be-created-original-error-instruments-crashed-on-star

I am having problem on memory leak tracking, i did try profiling but the instrument shows firapb_decode_repeated_user_attribute as as responsible object. And while i try to track code it takes me to assembly code which is more painful. Do anybody have similar issue or have some clue to track this issue, It will be a lot for me. Leaked Object # Address Size Responsible Library Responsible Frame Malloc 32 Bytes 1 0x600000231ba0 32 Bytes appName firapb_decode_repeated_user_attribute The Assembly code Yes as Larme said it was the Firebase leaking the memory. I am still not knowing the exact cause

When I run the following code (a simplified example, created to demonstrate the crash), it executes as expected when I choose Run (both os_log messages print in Console). However, when I open it in Instruments from the Memory Debug Navigator - by pressing Restart - it crashes (only the first os_log message prints in Console). The crash occurs at observe(...). import os import UIKit class ObserverCrashingExample: NSObject { @objc private var animation: UIViewPropertyAnimator? private var observer: NSKeyValueObservation? override init() { super.init() animation = UIViewPropertyAnimator( duration

Sometimes when I load a table view, and I'm performing no activity intentionally except letting the table view show, I'll wait a few seconds and then my CPU usage shoots up. How can I find the cause? Why might this thread be sucking up 99.9% CPU? I don't know. But here are some thoughts: The responsible library is UIKit . So it seems that some user interface code is broken. A function named FreeContextStack is running for a long time. pthread_once and pthread_getspecific take a considerable amount of time. These functions are fast, so they have to run very often. They are part of

Recently I have not been able to test for leaks with Instruments when running apps on a device. Instruments will attempt to take a snapshot but the status will freeze at "Analyzing Process". At first I thought it was just taking it's time but I have waited over 20 minutes for it and had no luck. It does still work fine on the simulator though. So far I have tried: - Using other devices with different ios versions - Restarting all devices - Updating Xcode to latest version - Running a number of different apps - Turning automatic snapshots off and trying manually Unfortunately none of the above
