xcode-instruments

When watching the debug graph in xcode 6 (and probably 5 too), when running my application the memory use continues to rise as I place more of a certain object on the screen and animate it's movement. It does not seem to decrease when I remove it. Once removed I believe there are no more references to them. See screenshot: http://i.stack.imgur.com/SnhbK.png However when I use Instruments to try to identify what's going on, there's only around 12mb persisting, and Total Bytes continues to rise, as expected. See screenshot: http://i.stack.imgur.com/VBwce.png Is this normal behaviour? What

Xcode Instruments: Leaks - App crashes on launch The app crashes on both, a device and in a Simulator. What could cause the app to crash with the Instruments attached, while working correctly when installed using the cable or over the air via Fabric. Update: Launching the "Allocations" instrument with the "Leaks" tab helps: Actually I think this is a bug of Instruments. Try to use the Allocations template instead, then click + and add the Leaks tool. 来源： https://stackoverflow.com/questions/49940506/xcode-instruments-leaks-app-crashes-on-launch

I am trying to use Instruments to find leaks within my app. I do it in the same way as I did before updating to Xcode 6.x. Since updating, it won't take any snapshots: the leaks instrument status displays "Analyzing process" and will never change. Both Xcode 6.0.1 and 6.1 GM 2 exhibit this problem. Any workaround? Seems like is a bug on iOS8 and not on Xcode. I have Xcode6.1 and the memory leak profiler seems to work on iOS7. As a workaround until Apple fix this (already reported the bug and was marked as duplicate) you can profile your memory leaks using a simulator. This issue seems to occur

Using hackintosh (i7-4790K 4GHz, 16GB DDR3, GF980Ti) for developing on Xcode (both Swift and Objective-C) about an year, never get any errors. But now I need to use Instruments apps (such Leaks, Allocations, Energy Log, System Trace, etc.) - but I can not! When I start ANY of these apps I see just transparent window without any visible information. Nax EDIT: as @Eike said in his answer, Instruments and other apps facing this issue work out of the box from 10.13 onwards. For 10.12, the NVWebDriverLibValFix kext is a better/less intrusive fix and avoid some permissions issues. This answer should

I've just started playing with Xcode 4, and found that, no matter how I setup debugging symbols in the project, Instruments refuses to display source lines for stack trace items that correspond to my code. In only shows hex offsets and identifies my executable as the owning module. Turning on "Source Location" draws a blank too. This occurs even for the skeleton OpenGL ES project generated by Xcode (File → New → New Project... → iOS → Application → OpenGL ES Application). This problem only occurs in Instruments (I've tried CPU and OpenGL tracing so far). Gdb picks up debug symbols just fine.

I'm trying to measure the energy usage level from my ipod when I run my application. I import the data from my device to Instruments app and the Energy usage level displays a bar graph. However, in the detail pane of Instruments the energy usage level don't show any number that indicate the level of energy used by the app in my device. Do you know how to get this energy usage level? I'm followed the steps stated in the Instruments Documentation to get the Energy Usage report from the iOS device; My iOS device is an ipod touch 3G and I'm using Xcode 3.0. Thanks!
